Electrical System Problems of Tesla Model Y - part 2

Hello, we have 46224 miles on the car currently. A couple of weeks back the whole battery died. Tesla replaced the battery and we picked up the car this past Friday, the xxx. After picking up the car the driver's seat does not slide. I looked it up online on the Tesla website as well as on the app and at both the places it was strongly recommended to bring the car back to Tesla as the problem was very very likely secondary to the battery replacement. The seat does not move at all. When I spoke to customer service at out local Tesla dealership in [xxx], the earliest date they could provide us was in the first week of August! this is an urgent issue. We happen to be away on vacation that week. So we were told to review the cost estimate and then find a date on the app to bring the car in. When I questioned the estimate price, I was told that this was the worst case scenario. But the invoice clearly states calibration, and 3 prices for a switch package all amounting to $364. 45 with tax!!! again I questioned this huge charge, considering the battery replacement and I was told almost rudely, "that does not seem to be the issue. " just not right!! information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The vehicle's indirect tpms showed a "pressure sensor fault (may clear next drive)" without issuing any "low tire pressure" alert. On July 20, 2026, while driving, the rear right tire lost pressure and disintegrated over a 10-minute drive. Despite severe tire failure that triggered multiple safety system alerts (traction control, stability control, automatic emergency braking, and lane departure avoidance disabled), the vehicle software failed to issue a critical "do not drive" command or explicit "flat tire" warning. Furthermore, the official Tesla app automated response advised that "most alerts may resolve automatically on your next drive," encouraging continued driving. This total absence of critical emergency alerts and misleading system guidance created an extreme, life-threatening road hazard and resulted in severe tire and wheel destruction.

My 2021 Tesla Model Y (VIN: 5yjygdee3mf231346) experienced a serious safety malfunction during a 12v low?voltage failure. When the vehicle displayed the 12v alert, it became non?functional. Upon entering, no systems were operating. When I pressed the brake pedal, the interior lights flashed and both front windows began moving up and down automatically without any input. This uncommanded movement caused both windows to shatter violently inside the cabin. The glass broke along the lower section of the window, consistent with internal mechanical stress caused by the window motor cycling during a fault. This was not external impact. I have photos documenting the breakage pattern. This is a safety defect. Automatic window movement during electrical failure poses a risk of injury. Additionally, even if a customer closes a door with the window raised, the glass should not shatter. Tesla vehicles are designed with automatic window indexing and motor resistance protection. The system should adjust the window position to prevent breakage. The fact that the glass shattered indicates a failure of Tesla’s safety logic and window indexing system. Tesla denied responsibility and claimed “misuse,” but could not provide system logs to support this claim. Tesla also stated customers must ensure windows are lowered before closing doors, but this requirement does not exist anywhere in Tesla’s manual. Tesla’s explanation does not address the automatic window movement that caused the breakage. This malfunction presents a clear safety hazard: unexpected window movement, glass shattering inside the cabin, and risk of injury to occupants. I request NHTSA investigate Tesla’s window indexing behavior during 12v failures, the failure of safety protections, and the risk of glass breakage caused by system?initiated movement.

Shortly after I purchased and activated Tesla full self-driving (supervised), my vehicle's driver-assistance system stopped functioning. Autopilot and fsd became unavailable, the vehicle cameras stopped functioning properly, gps/navigation positioning stopped functioning properly, and the vehicle could no longer communicate normally with the driver assistance system (das). Service mode testing showed das ethernet communication failure. I attempted multiple troubleshooting procedures, including vehicle reboots and resets. The low-voltage battery was also replaced, but the driver-assistance failure remained. I cancelled my fsd subscription on July 13, 2026 because the purchased feature was not functioning and sought assistance from Tesla. I subsequently had a Tesla service appointment on July 16, 2026. Tesla advised that the autopilot computer would need to be replaced and quoted approximately $3,000 for the repair/replacement. The failure occurred after the fsd purchase/activation and associated software changes. I am concerned that a Tesla software update or fsd-related software may have contributed to the hw3 autopilot computer failure, but I do not know the definitive technical cause. This is a safety concern because multiple driver-assistance and camera-dependent functions became unavailable simultaneously. The vehicle is available for inspection. I am requesting that NHTSA review this failure and compare it with similar hw3/autopilot computer failures reported by other Tesla owners.

Safety defect report: sudden power loss & falsified records 1. Incident & 5-hr towing (xxx): on xxx at ~16:30, while executing a low-speed (<10 mph) left turn in cambridge, MA, the vehicle had a sudden, total high-voltage failure mid-turn, losing all motive power and power steering without warning or error codes. Photos/videos were taken on-scene confirming zero physical impact or undercarriage collision. The dead vehicle stopped directly in the active lane, completely blocking traffic. With zero power, the driver and several helpful bystanders had to use extreme physical effort to manually push the dead car out of the road. Aaa arrived at 18:00 but could not tow because total power loss completely locked all 4 wheels/brakes (no tow mode). Aaa dispatched a 2nd specialized flatbed with dollies (arrived 21:00). Driver was stranded on-site for over 5 hours. Car reached Tesla dedham service at 22:00. On xxx at 10:00 am, driver reported the driving power loss in person at dedham, handed over key, and got a loaner. 2. Written notice (xxx): on xxx, explicit written notice was sent to Tesla service manager taso, re-confirming the exact mid-driving power loss hazard. 3. Tesla diagnosis & repairs: invoice #xxx confirms a severe high-voltage failure: "a hardware overcurrent event caused small high voltage battery brick imbalance and rear inverter failure. " Tesla replaced rear drive unit inverter (3du) and pyrotechnic battery disconnect (pyrofuse). 4. Falsification of safety issue: despite 5-hr towing from wheel lock-up, xxx in-person report, and xxx written notice detailing mid-turn power loss, Tesla falsely recorded on invoice: "customer states: vehicle will not charge. " this is deliberate falsification and deceptive practice by Tesla to downplay a critical road hazard into a benign charging issue. I request NHTSA to investigate this high-voltage overcurrent/inverter failure pattern and Tesla's practice of altering safe information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On July 10, 2026, my 2024 Tesla Model Y (approx. 22,440 miles) lost all power (main/12v battery) while parked next to a supercharger stall on level 3 of the harrah's ak-chin casino parking garage, maricopa, az. Ambient temperature was approximately 110f. My dog and cat were inside the vehicle. With the vehicle powered off, the key card, Tesla app, and interior door releases did not function, leaving no way to open the doors from outside or inside. Unable to find or access a working manual door release in time, we broke the rear quarter glass and damaged a door to physically extract the pets before they suffered heat-related harm. Maricopa police department and ak-chin fire department responded to the scene. This represents a serious safety defect: a loss of vehicle power should not eliminate all means of entry/egress, particularly when children or pets could be trapped in extreme heat. The vehicle, damaged door, and glass are available for inspection. Photos of the incident are available.

Fsd / vision system , no warnings , the vehicle is turning left and right on a straight road sunny conditions. I have a video that it wouldn’t let me attach to the case. I had Tesla service review this and they told me it’s standard behavior, this never occurred before and is dangerous and unusable. Autopilot has an issue that Tesla themself can’t detect and when I get into an accident it’ll be too late. I’ve been complaining about this for 3 months and Tesla keeps telling me it’s standard behavior, this never happened before the car used to drive straight, brand new tires front and back , blanket and aligned the car drives straight while not in autopilot, issue is directly related to fsd and Tesla autopilot.

Subject: urgent safety defect: post-disengagement touchscreen prompt causes acute driver distraction feature involved: full self-driving (supervised) post-takeover feedback modal safety concern: when a driver manually disengages fsd (supervised), it is almost always because the vehicle entered a complex, unexpected, or hazardous scenario that demanded immediate human intervention. At the exact second the driver assumes physical control of the vehicle—when 100% of driver visual attention and cognitive bandwidth must be on the roadway—the center display flashes a persistent multi-choice survey requesting feedback on why the disengagement occurred. The hazard: visual diversion during critical moments: presenting bright, interactive ui cards requiring glance time and manual touch interaction immediately after a takeover directly contradicts basic human-factors engineering and crash avoidance principles. Cognitive overload: instead of stabilizing the vehicle in manual control, the driver's attention is competed for by an on-screen prompt asking for data categorization. Ui contradiction: while the cabin camera actively penalizes drivers for split-second glances away from the road, the vehicle os simultaneously prompts the driver to look at and touch the center screen during the most dangerous phase of a driving sequence. Requested remediation: provide a toggle under controls > autopilot to disable post-disengagement prompts entirely (e. G. , "prompt for takeover feedback: off"), or suppress all on-screen interactive surveys until the vehicle is placed in park. Driver telemetry collection should never compromise active collision avoidance. --- this issues happens whenever disengaging fsd. Its not a one time thing. They have updated the software in my car multiple times but haven't fixed this. My location doesn't matter, speed doesn't matter. They added it in an update after more that two years of using the car and I cannot get rid of it.

On Saturday, [xxx] at around [xxx] going west on [xxx] toward [xxx] stopped at the intersection of [xxx]. While driving my 2022 Tesla Model Y, performance, I was stopped at a red light. When the light turned green and I began accelerating normally through the intersection, both passenger-side doors unexpectedly unlatched at the same time. The windows on both passenger doors lowered slightly, and the vehicle displayed a warning indicating the doors were open and to drive carefully. This created an immediate safety hazard, as the doors opened while the vehicle was in motion without any intentional action from the occupants(there were 0 occupants there). This is the second time this exact issue has occurred under similar circumstances, with the previous incident also happening as I accelerated from a red light. The vehicle should not allow multiple doors to unlatch while driving. I have reported the issue to Tesla for inspection and request that this incident be documented and investigated as a potential safety defect. I was going less that 10 mph when this occurred. Thankfully, my toddler was not sitting in the back seat and there were no passengers in the car. No injuries. No crash. *unable to upload any photos/screenshots at the moment, but can email or link a drive when need be. This website doesn't support any uploads at the moment. I'm on a mac using google chrome.

The high volatage heat pumps stopped working after 3 months and they left me without a loaner or credit for transportation.

On June 17, 2026, I experienced a severe and life-threatening entrapment inside my 2020 Tesla Model Y. The incident occurred immediately after I finished charging the vehicle for approximately two hours at a charging station under direct sunlight, which left the car extremely hot. After charging, I drove a short distance, parked, and left the vehicle for approximately 20 minutes. Upon my return, my card key failed to unlock the vehicle. After contacting my wife for assistance, I was briefly able to open the door, but I became securely locked inside the cabin as soon as the door closed. The 12v battery had completely failed without any advanced warning or vehicle alarm. All power was lost. The windows were fully rolled up, the climate control stopped, and there was no airflow. The cabin temperature was rapidly rising due to the earlier sun exposure. In a state of panic and facing a dangerously overheating cabin, I called my wife to inform her that I needed to break a window. I struck the windshield to draw the attention of passersby, which cracked the glass but did not shatter it. I then attempted to force a side window outward to establish ventilation and crawled into the back seat to try to open the trunk, but all electronic and external release mechanisms were unresponsive. After regaining composure, I used my phone to look up emergency solutions online and ultimately located the manual mechanical door release. I was able to escape.

While driving my 2026 Tesla Model Y in June 2026, the vehicle suddenly applied steering input on its own and began swerving left and right even though there were no obstacles in the road. I was driving on a straight section of roadway, centered in my lane, when the steering wheel started moving by itself as if the lane keeping system and steering were confused. I had to fight the wheel in both directions to keep the car from veering toward the curb and toward the adjacent lane. It felt like struggling against another person at the wheel. Fortunately there were no vehicles directly beside me at that moment, so I was able to avoid a collision, but this behavior could easily cause an accident for a typical driver. This incident is part of an ongoing pattern of safety issues with this vehicle. Since late 2025, I have experienced multiple events where the car fails to respond to the accelerator after shifting into drive and behaves as if it is in neutral until I shift back to park and then into drive again including a complete loss of propulsion while driving in moderate traffic. Tesla has already performed recall repairs on the battery/battery contactors and multiple diagnostic visits for intermittent loss of propulsion and steering concerns, but the problems continue. I am filing this complaint because I believe there is a serious defect involving the steering, propulsion system, and lane keeping driver assist systems that could cause loss of control and a crash.

On June 7, 2026, my 2021 Tesla Model Y with approximately 37,131 miles became completely unresponsive and could not be driven. Tesla mobile service replaced the 12v low-voltage battery on June 11, 2026. The official repair notes stated that the battery was replaced, proper operation was verified, there were no active alerts, and the vehicle was in excellent condition. Shortly after this repair, multiple vehicle systems stopped functioning, including all cameras, navigation/gps, and software/firmware updates. Tesla service later diagnosed the vehicle as requiring replacement of the hw3 vehicle computer at a cost of approximately $3,066. The loss of camera functionality disabled or affected multiple driver assistance features that rely on the camera system. The vehicle has been unavailable for approximately one month while awaiting repair. During discussions with Tesla service regarding the diagnosis, I was informed verbally by the service manager that they see similar hw3 computer-related issues on a regular basis (approximately every other week). I cannot independently verify that statement, but I am including it because it contributed to my concern that this may not be an isolated incident. I am not asserting the root cause of the failure. I am submitting this complaint because the loss of the vehicle’s camera system and related driver assistance functionality may represent a potential safety concern, and I believe NHTSA should be aware of this incident.

This is reference my existing odi number 11742309. On June 4, 2026, while driving slowly into a parking space, the vehicle experienced a sudden and unintended acceleration. I applied the brake, but the vehicle did not respond as commanded, resulting in a collision. The vehicle was approximately 3 months old at the time of this incident.

On xxx at approximately 9:30am, my 2026 Tesla Model Y suddenly accelerated without driver input while parking at the center at [xxx], [xxx]. Vehicle surged forward unexpectedly. I immediately applied brakes. No warning messages appeared before or during the incident. Vehicle struck parking lot curb. Police responded and vehicle was towed. Physical evidence including tire drag marks and vehicle debris remain at scene. Requesting full edr data log preservation. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I purchased a new 2026 Tesla Model Y standard and took delivery on approximately 30 may 2026. Within the first week of ownership, the vehicle displayed multiple safety-related warnings, including: * steering assist reduced * power braking assist reduced * automatic emergency braking unavailable * lane departure avoidance features unavailable * automatic vehicle hold disabled the warnings have occurred more than once. They initially disappeared and then returned on a later drive. Both incidents occurred while the vehicle was operating with full self-driving (fsd) engaged. During the most recent occurrence, while parking at less than 3 mph, the vehicle’s braking assistance appeared reduced and the brake pedal required significantly more effort than normal. As a result, I nearly struck a curb because the vehicle did not slow as expected. The warnings indicated that increased steering and braking effort may be required. Because the vehicle is brand new and these warnings involve steering, braking, and collision-avoidance systems, I believe this creates a significant safety risk. I no longer feel the vehicle is safe to drive until it is inspected and repaired. Tesla has been notified and a service request has been initiated.

The contact owned a 2022 Tesla Model Y. The contact stated that while driving at an undisclosed speed, the central computer suddenly overheated. The failure caused the vehicle to stop immediately and disabled other essential safety features. During the failure, the center screen flashed red with a message instructing the driver to take control, followed by a series of unknown error codes and an "app_w141 ecu thermal alert" warning. After researching, the contact discovered that the failure might have been caused by a recent software update from the manufacturer. The manufacturer was notified of the failure, and a Tesla service center confirmed the failure as a hardware 3 computer failure. The contact was informed that the system needed to be replaced. The failure mileage was 95,000.

The contact owns a 2026 Tesla Model Y. The contact stated that while driving at 65 mph, with the autopilot feature engaged, the vehicle approached a lane closure as big, metal arrow road signs where on the road indicating the road closure. The contact, who was distracted at the time, expected the vehicle to acknowledge the road closure and switch lanes. The vehicle failed to recognize the chevron barricade lights on the highway and the vehicle ran through the road signs without warning. The contact was forced to take over and stop the vehicle due to the failure. Due to the failure, the front, driver side mirror detached from the vehicle. The contact exited the highway and inspected the damage to the vehicle. Despite the failure, the contact managed to drive the vehicle home. The service center was notified of the failure and an appointment was made to have the damages repaired. The cause of the failure had yet to be determined. The vehicle was not repaired. The failure mileage was approximately 21,000.

A 2023 Tesla Model Y experienced a sudden electrical failure while parked/being prepared for use. Multiple warnings appeared on may 26, 2026, including high-voltage system service required, low-voltage electrical system power reduced/vehicle shutting down, cabin climate control limited, and steering/braking/parking brake functions degraded. The vehicle could not be driven normally and required flatbed recovery. The failure created a safety concern because the vehicle showed high-voltage and low-voltage faults together with steering/braking/parking brake warnings and could have left the vehicle disabled without reliable restart or parking brake function. The manufacturer service center inspected and repaired the vehicle after several days. The component should be available through manufacturer service records, and screenshots of the warnings, tow/recovery, and service records are available.

Am reporting a serious safety concern involving a 2025 Tesla Model Y, VIN [xxx] . On [xxx], the vehicle was being driven on [xxx] in columbus, ohio while the driver was traveling to columbus preparatory academy. During the trip, the steering reportedly stopped responding properly, and the driver struggled to control the vehicle. Witnesses at the scene reported that the driver appeared to be fighting with the steering and trying to stop the vehicle or prevent it from drifting. The vehicle then lost control, accelerated or continued moving uncontrollably, flipped/rolled over, and sustained major damage. A police report was created by the columbus police department under report number [xxx]. The vehicle involved is a 2025 Tesla Model Y. This was a serious crash involving a possible steering malfunction, loss of control, and rollover. The vehicle is currently located at pro-cars, 400 stimmel rd, columbus, OH 43223. Tesla was contacted after the incident, and the representative advised that the vehicle should be taken to a collision center. I am filing this complaint because the incident appears to involve a potential safety defect affecting steering control and vehicle control. I request that NHTSA review this matter as a possible vehicle safety defect. The vehicle has not yet been repaired, and I am attempting to preserve it for inspection. I have supporting materials including the police report, photos/videos, witness information if needed, towing/storage documentation, and communications regarding the vehicle. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Tesla 2026 Model Y was involved in a severe motor vehicle accident directly caused by a critical software and/or hardware malfunction of Tesla’s full self-driving (fsd) system. At the time of the incident, the vehicle’s full self-driving (supervised) software suite was actively engaged and driving the vehicle. While navigating, the system suffered an abrupt and uncommented control malfunction. Despite prompt attention, the autonomous system executed an erratic, uncorrectable maneuver that overrode human intervention thresholds, completely failed to respond safely to the immediate driving environment, and directly caused a collision.

I am reporting a recurring and unresolved electrical/safety issue with my new Tesla Model Y. The issue has occurred 5 times within the past 4 weeks and affects multiple systems simultaneously. When the issue occurs: * the air conditioning stops working completely. * the driver-side front and rear windows cannot be rolled down or up. * the driver seat adjustment may not function properly. The problem appears intermittently. It may disappear temporarily and then return hours or days later. Tesla service has inspected the vehicle multiple times, but the issue continues to recur. This creates a significant safety concern because: * the driver window may not function during rain or emergencies. * the ac may fail during extremely hot weather. * the driver seat may not adjust properly, potentially affecting safe vehicle operation and driver visibility. * the intermittent nature of the failure makes the vehicle unpredictable and unreliable to operate safely. The issue has not been permanently resolved despite repeated service visits. I am concerned there may be a broader electrical or control system defect affecting vehicle safety.

Component or system that failed: the gps navigation system and cellular connectivity module in my 2024 Tesla Model Y (VIN: [xxx] ) have intermittently lost signal and become completely nonfunctional multiple times over the past month. Tesla's service documentation indicates this affects the vehicle's connectivity hardware or managing software. The vehicle is available for inspection upon request. Safety risk: loss of gps navigation while driving creates a safety hazard when traveling unfamiliar routes, in low-visibility conditions, or during emergencies. Loss of cellular connectivity simultaneously disables Tesla's roadside assistance and the vehicle's calling capability. The vehicle acknowledges this risk by displaying a yellow caution alert reading "poor gps location accuracy — additional attention may be required" on the primary touchscreen while in motion, with no advance warning before the failure occurs. Reproduced or confirmed by a dealer or service center: yes. On may 22, 2026, Tesla service columbia-two notch rd, 6301 two notch road, columbia, SC 29223, confirmed this as a known issue. The service advisor stated Tesla is aware of the defect but has no repair available and instructed me to submit in-car bug reports each time it occurs. Inspected by manufacturer or others: yes, by Tesla's service center on may 22, 2026. No independent, police, or insurance inspection has been performed. Warning lamps or prior symptoms: a yellow triangle caution icon with the message "poor gps location accuracy — additional attention may be required" appears on the primary touchscreen during each failure, but only after gps has already degraded — no advance warning is given. This has occurred four times since April 2026, with each event lasting between 15 seconds and over one minute. Unknown as to specific trigger conditions. Photographic documentation has been retained. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I reporting a potential safety-related defect involving my 2023 Tesla Model Y performance. Since shortly after purchasing the vehicle in April 2026, it has repeatedly been unable to successfully install Tesla software updates. The updates download, but the installation repeatedly fails. I have attempted installation multiple times under appropriate conditions, including adequate battery charge, stable WI-fi, vehicle reboot, removal of usb devices, and installation directly from the vehicle touchscreen. The failures continue. Tesla evaluated the vehicle and documented the failed software installation. Tesla also identified a possible issue involving the hw3 car computer and prepared an estimate of approximately $3,000 that included replacement of the vehicle computer, diagnostic work, and labor. I am concerned because Tesla vehicles rely extensively on their onboard computers and software for vehicle operation, safety systems, driver-assistance functions, security updates, bug fixes, and manufacturer-issued corrections. Because this vehicle cannot successfully install software updates, I am concerned it may be unable to receive safety-related corrections or updates that other vehicles are receiving. This is not simply an infotainment issue. The failure appears to involve the vehicle computer itself and has continued despite repeated troubleshooting and Tesla service involvement. I believe NHTSA should evaluate whether defective hw3 computers or related electronic systems can cause repeated update-installation failures and potentially prevent affected Tesla vehicles from receiving safety-related software updates or recall remedies.

On may 8, 2026 at approximately 1:15 pm in [xxx] , my 2023 Tesla Model Y unexpectedly locked with my [xxx] infant inside during approximately 100°f weather. I briefly exited the vehicle while charging to disconnect the charging cable. My authenticated phone key remained inside the cabin. Immediately after unplugging the charger, the vehicle activated walk-away door lock and locked all doors despite the phone key remaining inside the vehicle. I was locked out without access to my phone and had to ask a stranger to call 911 and contact my husband. Cabin temperatures rapidly became dangerous for an infant. My husband was eventually able to remotely unlock the vehicle using the Tesla app, narrowly avoiding forced entry by emergency responders. The vehicle failed to detect the phone key inside the cabin and improperly initiated locking while a vulnerable child occupant was present. This created a serious risk of heat injury or death. The vehicle also failed to prevent the lockout despite an infant occupant being seated in the second row, raising concerns about whether rear-seat occupancy detection and child safety protections functioned properly during the event. I am requesting investigation into Tesla’s proximity sensing, phone key detection, walk-away lock behavior, and child occupant safety protections during charging/unplugging events. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The vehicle began experiencing repeated autopilot/fsd failures while driving. Symptoms included sudden autopilot disengagements, cruise control becoming unavailable, and loss of road visualization/navigation display functionality. The issue progressively worsened over time. The vehicle was first brought to Tesla service in 2025 for the same overheating-related concern. At that time, Tesla identified a coolant-related issue, topped off the coolant system, and returned the vehicle to service. However, the problem continued and gradually became more frequent and severe afterward. During the most recent service visit, Tesla diagnosed the hw3 autopilot computer as overheating due to a heat transfer failure between the autopilot board and cooling cold plate. Tesla stated that heat generated by the board could no longer be efficiently transferred to the coolant system, causing the autopilot computer to overheat. Tesla further advised that continued operation without repair could eventually impact additional vehicle functions, including the center display screen shutting off due to overheating-related failures. Given the loss of driver-assistance functionality and potential impact to core vehicle systems, I am submitting this report so the issue is documented as a potential thermal management or hardware reliability concern involving the hw3 autopilot computer system.

While driving on I-95 north in the fast lane at highway speed, my 2023 Tesla Model Y experienced a sudden loss of propulsion and displayed a warning indicating the vehicle was shutting down. The vehicle rapidly decelerated and would not respond to acceleration or drive engagement. Steering remained functional, which allowed me to maneuver the vehicle across lanes to the shoulder to avoid a potential collision. This required an emergency maneuver in active highway traffic with my family in the vehicle. A soft reset did not resolve the issue. After performing a hard reset, I was able to move the vehicle slowly off the roadway to a nearby location where it was later towed. This incident occurred without prior warning and created a significant safety hazard due to sudden loss of propulsion at highway speed.

My 2021 Tesla Model Y hw3 experienced complete failure of all cameras, gps, automatic emergency braking, and adaptive cruise control following the installation of software update 2026. 8. 6. 1 — the ota remedy update issued by Tesla for NHTSA recall 26v283000. The vehicle was fully functional prior to this update. The failure was confirmed and reproduced by Tesla's authorized service center. The service advisor confirmed in writing: "during the update, the computer failed to reboot properly. We attempted to perform a 12v reset but unfortunately it is still stuck in the boot loop state. " the autopilot ecu (primary/turbo a) is stuck in a permanent boot loop and cannot be recovered by software means. Safety impact: all cameras including rearview camera are completely non-functional. Automatic emergency braking and all adas features are disabled. The vehicle cannot safely detect obstacles or pedestrians. Gps navigation is frozen. Tesla has confirmed the computer requires replacement but is classifying it as a customer-pay repair citing expired warranty, despite the failure occurring during Tesla's own recall remedy software deployment. This vehicle meets every technical criterion of recall 26v283000 — hw3 hardware, 2021 Model Y, software version 2026. 8. 6. 1, complete camera failure — but does not appear in the recall VIN database. I am requesting NHTSA review whether this VIN should be included in recall 26v283000 or a related investigation.

I took delivery of a brand new Tesla Model Y today in austin, texas. Within less than two hours of delivery, the vehicle experienced two separate and serious failures while driving. During the first incident, the vehicle suddenly stopped in the middle of the road without any warning while I was driving. The vehicle became completely unresponsive and came to a stop in active traffic. I immediately contacted Tesla service for assistance. The representative advised me not to worry and stated that the vehicle likely came to a safe stop location and that there appeared to be no issue since the system had recovered. I was told the vehicle was safe to continue driving. However, this information did not reflect what actually occurred. The vehicle had stopped in the middle of an active roadway, not in a safe location. After the system temporarily became operable again, I continued driving as instructed. However, during a second drive shortly after, the exact same issue occurred again within approximately 10–15 minutes, this time on a much larger and heavily trafficked road. When the vehicle stopped both times, it became completely electronically controlled and unresponsive. There was no manual way to move or safely reposition the vehicle. I was stranded in the middle of moving traffic on a major road, unable to control or move the car in any way. I felt that my life was in danger due to the inability to regain control or remove the vehicle from traffic. Both incidents occurred on the same day of delivery within a very short time frame, making the vehicle completely unreliable and unsafe to operate. At least one of the incidents occurred while using self-driving features. Due to the repeated failures, the severe safety risk, and the incorrect reassurance provided during the first incident, I no longer feel safe operating this vehicle. I am requesting a buyback or refund rather than repair, as this issue occurred immediately after delivery and represents a critical safety conce.

As a 100% t&p disabled veteran relying on advanced driver-assistance for mobility, I purchased a 2022 Tesla Model Y performance with hardware 3 (hw3), which was actively advertised and sold as possessing all necessary hardware for safe, autonomous operation. In practice, the vehicle suffers from safety-critical driver-assist defects—including unexpected disengagements and erratic system choices—due to fundamental hw3 processing and memory bandwidth limitations. Operating a vehicle marketed as autonomy-ready, but constrained by hardware incapable of handling complex traffic scenarios safely, forces constant manual intervention and creates an unacceptable collision hazard for a disabled driver.

### summary: sudden unintended acceleration (sua) from a stationary position. ### vehicle configuration: 2023 Tesla Model Y long range awd. Battery type: nmc. ### incident details: on April 19, 2026, at approximately 10:00 a. M. , the vehicle was stationary on a flat surface at 6722 vista del Mar Ave, san diego. I was in the driver's seat with the vehicle "on" but stopped, conversing with two witnesses. My feet were completely clear of both the accelerator and brake pedals. ### the event: without driver input, the vehicle suddenly and forcefully accelerated forward. I immediately slammed the service brake with full force. The vehicle traveled approximately 20 feet before the brakes brought the car to a halt. ### evidence & gaps: two eyewitnesses confirmed the vehicle moved autonomously without pedal interaction. A manufacturer data report was requested, but it showed a specific data gap for the exact seconds of the acceleration event, despite providing second-by-second logs for the rest of the day.

I am reporting multiple safety-related failures with my Tesla Model Y, purchased December 18, 2025. Within four months of ownership, the vehicle has experienced escalating issues: on April 19, 2026, while driving approximately 70 mph on a freeway in heavy rain, the vehicle suddenly lost power and decelerated to approximately 20 mph. Multiple safety systems became unavailable simultaneously, including automatic emergency braking, traction control, stability control, and vehicle hold. I was able to pull to the side of the road, but the vehicle would not restart and required towing. This created a dangerous situation and significantly compromised my ability to safely control the vehicle. On April 9, 2026, a rear seatbelt unlatched under braking while in use. This is a serious safety concern, as the passenger was not properly restrained and had to brace themselves. On February 10, 2026, the vehicle experienced repeated software failures causing lockouts. In one incident, I was locked out while my [xxx] child was inside the vehicle. On January 2, 2026, the vehicle required service for a cracked window shortly after delivery. The vehicle has been taken in for service multiple times, and although repairs were performed, new and increasingly serious failures have continued to occur. I am concerned about the safety of operating this vehicle, particularly due to the loss of power at highway speed and failure of safety systems.

I am reporting two unresolved safety-related defects on my 2021 Tesla Model Y (VIN: [xxx] ) that occurred following paid service at Tesla's league city service center on 04/16/2026 defect 1 — computer and sensor system failure: the vehicle's onboard computer cuts in and out intermittently. Sensors fail during operation and the problem worsens significantly in high-temperature conditions. Tesla vehicles rely on their computer and sensor systems for core safety functions including collision avoidance, autopilot, and driver assist features. Intermittent failure of these systems while operating the vehicle is a safety hazard to the driver and the public. Defect 2 — glove box inoperable: the glove box does not open following Tesla service. The glove box in Tesla vehicles houses key vehicle documentation and is integrated into the vehicle's locking and security system. I paid $2,497. 50 for service on [06/16/2026]. Both defects were either caused or left unresolved by that service. I have notified Tesla service staff directly and followed up multiple times over more than four weeks. Tesla has not responded, has not scheduled any repair, and has not refunded my money. I am filing this complaint because (1) the sensor and computer failures present an active safety risk during operation, (2) Tesla has ignored all attempts to resolve this, and (3) public reviews indicate this is a pattern affecting multiple consumers. I request that NHTSA investigate and determine whether a safety defect investigation or recall is warranted. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The rear subframe wiring harness on my Tesla contains a significant design flaw that creates an unreasonable safety risk. The factory-installed corrugated protective tubing (wire loom) terminates prematurely, leaving approximately 1 inch of critical wiring completely exposed at the connector. This specific harness uses soy-based insulation, which is a known attractant to rodents. Because of the 1-inch gap in protection, rodents have been able to sever the same connector twice within a 30-day period safety risk: the exposed wires in the rear subframe harness are responsible for rear drive unit communication / wheel speed sensors / brakes]. A failure of these wires while the vehicle is in motion could result in a sudden loss of propulsion, unexpected braking, or the loss of stability control systems. This creates a high risk of a collision, particularly at highway speeds.

I am reporting a serious safety concern involving my Tesla Model Y. While driving, the vehicle’s main center screen (mcu) suddenly failed and entered a continuous reboot loop. This resulted in the loss of critical driving information and controls, including navigation, camera display, and vehicle system status. The issue occurred without any warning and nearly caused a serious accident, as I was unable to safely monitor essential driving information. This failure made the vehicle extremely unsafe to operate. The problem appears to be related to a known mcu system failure affecting some Tesla vehicles. I am concerned that this issue may present a broader safety risk for other drivers. Please investigate this matter for potential safety defects.
