Electrical System Problems of Tesla Model Y - part 1

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 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).

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.

### 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. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

**what component or system failed or malfunctioned, and is it available for inspection upon request?** the vehicle experienced a critical failure immediately on the same day of purchase, rendering it not functioning or inoperable. It was deemed to be preexisting from the dealership I bought it from. The battery is malfunctioning affecting the driving capacity and range. --- * was your safety or the safety of others put at risk?** the failure created a significant safety concern, as the vehicle was not operating reliably immediately after purchase. This placed me at risk of being stranded and potentially exposed to hazardous conditions, including loss of transportation in unsafe or uncontrolled environments. Or stopping while driving. --- * the problem been reproduced or confirmed by a dealer or independent service center?** the issue was immediately reported to the dealership, and they acknowledged the problem by agreeing to an exchange of the vehicle due to its defective condition. It was confirmed by a service center of the car's manufacturer. --- * the vehicle or component been inspected by the manufacturer, police, insurance representatives or others?** at this time, the vehicle has inspected by the manufacturer. --- **were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?** yes, although the manufacturer can't pinpoint when they started but said they had been on since atleast March 10. My purchase was made April 1, undisclosed to me of this huge issue.

My 2023 Tesla Model Y suddenly became inaccessible via key card and phone key with no prior warning. The tow operator successfully jump-started the vehicle with a 12v jump and it powered on — suggesting a 12v battery failure, not an hv system failure. Tesla diagnosed water ingress in the hv battery pack and hv harness, citing an isolation resistance fault and open flood port. Their conclusion escalated from "water ingress" to "vehicle submerged," with an $11,000 battery replacement recommended and warranty denied. I am disputing this. The vehicle has never been submerged or exposed to flooding. The only physical evidence provided was clean water droplets on a single hv connector — no waterline staining, no sediment, no debris, no pin corrosion. No ingress pathway (seal, gasket, or breach point) was identified. The flood port mechanism was not explained and may activate from pressure changes or seal failure — not exclusively submersion. The vehicle powering on after a 12v jump is inconsistent with catastrophic hv failure from submersion. I believe this may represent a manufacturing defect in the hv battery pack sealing system allowing moisture intrusion under normal conditions. Tesla has classified this as owner-caused damage without sufficient physical evidence. If similar cases exist across 2023 Model Y vehicles, a systemic defect may be present. Safety risk: sudden, complete vehicle shutdown with no warning — potential loss of propulsion while driving. Vehicle is currently at Tesla service, undisassembled, and available for inspection.

Upon delivery of the vehicle the passenger door would not open from the outside. Multiple vehicle settings were reviewed, and a repair was scheduled to fix the issue.

On March 23, 2026, my vehicle experienced a sudden and simultaneous failure of multiple critical safety systems without any prior warning. The alerts displayed included: automatic emergency braking unavailable, traction control disabled, stability control disabled, and additional driver-assistance features becoming unavailable. This incident created a serious safety hazard, as the loss of these systems significantly reduces vehicle stability and braking assistance, increasing the risk of loss of control, especially at highway speeds or in adverse weather conditions. In addition, the front-facing camera exhibits fogging and reduced visibility during cloudy and rainy conditions, which further impacts the reliability of safety and driver-assistance systems. Based on my research, similar issues have been reported by other Tesla owners, suggesting this may not be an isolated incident but a potential pattern defect. I am concerned about the safety of operating this vehicle and request that this matter be investigated for potential defects affecting critical safety systems.

I was entering the on-ramp to [xxx] , from [xxx] , to merge onto the freeway east bound towards [xxx] , when my Tesla suddenly lost all power, the brakes did not work and the power steering completely failed making it feel like it was locked up. I was traveling approximately 40-50 mph at the time nearing the gore point to merge onto the freeway. Fortunately I was in the inside lane and I rolled to a stop away from other vehicles. I could not steer at all. Had I been completely on the freeway, I could have been rear ended badly. I had my two young boys in the vehicle with me, both [xxx] and [xxx] . We were completely trapped in the vehicle with no power. My [xxx] old remembered to use the manual latch to get out. I opened my door manually and it broke my driver side glass window. Vehicles were passing us rapidly to enter the freeway. I called my husband who is a police officer and he came and picked us up. We called Tesla who said they could not get a read on our battery whatsoever. We called a tow company and had this vehicle towed to Tesla repair center in [xxx] , after reporting our traumatic event. They claim our warranty is expired, but our vehicle only has 37,638 miles and should be covered under the 8 year, 120,000 mile warranty that covers a major malfunction like this. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While on my way to run an errand, I opened up the back door to strap my 2 year old in, when I closed the door, the car would not open whatsoever, after trying for a few minutes with the phone key app for Tesla and the physical key fob, nothing would work. I had to end up calling 911 and firefighters came out and had to physically open the door, which broke the window. The car was completely unresponsive and would not turn on. After researching what happened, it turns out the 12v battery had died. I was able to jumpstart the car with jumpers and that was able to open up the rest of the car's doors. However, during the time my son was stuck inside with the over 95 degree weather, the had no safety mechanism in place to open it physically like a traditional key fob would. It is very disheartening knowing my son could have potentially lost his life over something so simple that could be resolved with a physical keyhole on the outside like almost every traditional vehicle has. This is something that should not occur, ever. The fact that the car was able to open up once more before completely dying and perfectly at the wrong time after closing the door while my son was trapped in there in complete heat was very disappointing.

Following a "secondary" botched windshield replacement within 3 weeks performed by the Tesla service center in carle place, NY, my Tesla Model Y experienced a catastrophic structural water intrusion during rainfall. A great amounts of water dripping directly through the windshield seal into the cabin, soaking the dashboard electronics, floorboards, and much more water coming in from the brake pedal area while driving on lie. While I was driving the vehicle with my three children in the back seat, this water intrusion triggered an active electrical short circuit. The vehicle's hazard lights began flashing autonomously, and the electrical system became severely compromised, creating an immediate and life-threatening safety hazard on the road. The vehicle is currently grounded, completely undrivable, and poses a continued electrical fire risk. Tesla service has been notified in writing and has officially acknowledged via their app that the vehicle must be towed. This gross negligence in structural sealing has directly compromised the vehicle's electrical control modules, severely endangering the lives of the occupants. ".

I am writing to bring to your immediate attention a serious safety incident involving our brand?new 2026 Tesla Model Y (juniper), equipped with fsd version 14. 2. 2. 5 and software version 2025. 45. 10. We purchased this vehicle as our dream car, and for nearly six months it delivered exactly what we hoped for—innovation, safety, and an exceptional driving experience. That trust was the foundation of our decision to choose Tesla. On [xxx], at approximately [xxx] in frisco, TX, that trust was shaken by a sudden and alarming event. After coming to a stop and while making a routine right turn at under 10 mph, the vehicle unexpectedly accelerated on its own, causing an immediate loss of control. The entire incident unfolded in seconds, leaving no opportunity to react or correct the vehicle’s behavior. The incident happened at the intersection of [xxx]. The "autopilot" feature in Tesla was on at the time of the incident. The impact was severe. The airbags deployed, the vehicle was declared a total loss by insurance, and first responders—including the frisco police department—were required to clear the wreckage. My wife sustained injuries in the crash and continues to recover. Witnesses at the scene confirmed that the acceleration was abrupt and not driver?initiated. The emotional and physical toll has been significant. More importantly, the nature of this incident raises serious concerns about a potential safety issue that could affect other Tesla owners. We feel compelled to ensure this incident is thoroughly examined. If there is a systemic issue—software?related or otherwise—it is critical that it be identified and addressed to protect other drivers and uphold the integrity of the Tesla name. We truly miss our vehicle and the confidence we once had in it. We hope Tesla will treat this matter with the seriousness it deserves and provide a transparent path forward. Thank you for your time, attention, and commitment to safety. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My driver side headlight assembly stopped working. The headlight assembly includes the driving lights, high beams, and turn signals. I am open to having this product inspected upon request. This impacts the safety of me and others due to decreased visibility and the inability to appropriately indicate when I am turning. The dealer has not reviewed this yet, but I have a scheduled appointment on Friday, April 24. Vehicle has not been inspected by any third-party, improving manufacturer, police, insurance, or other representatives. There were no warning, lamps, messages, other symptoms of the problem prior to failure. The failure first appeared at around 55,000 miles, which was 5000 miles beyond my warranty. I believe that Tesla is pushing out updates that intentionally cause light assemblies and other high priced items to stop working after the warranty. There are multiple instances people replacing the same fixture after their warranty period has expired. Tesla charges $2000 to replace one light fixture. I believe this is fraudulent and corrupt business practices by Tesla.

The front trunk (frunk) actuator failed due to an under voltage condition. During repair, Tesla technicians also found corrosion in the wiring harness connectors. The vehicle has been garaged its entire life and has never been exposed to harsh environmental conditions. Tesla's own service documentation specifies that underwood and underbody connectors should be protected with anti-corrosion grease during assembly. Premature corrosion on a grade vehicle at 78,000 miles suggests a manufacturing defect in either the harness materials or the factory assembly process. Repair cost $860. 20, partially offset by a $200 goodwill credit. A non-functional frunk also represents a potential safety concern as the hood latch mechanism is part of vehicle safety systems.

On [xxx] I pick up my new Tesla y. On [xxx], while traveling at highway speeds on [xxx] with autopilot "fsd" engaged, my 2026 Tesla Model Y experienced a sudden vehicle shutdown and start giving multiple alerts without warning. The vehicle displayed multiple critical alerts: "vehicle shutdown", "pull over safely", "stability control disabled. " upon the failure, autopilot fsd disengaged, and the power steering immediately became extremely heavy ("hard"), making the vehicle difficult to steer. The car lost all propulsion. I had to manually maneuver the heavy, unpowered vehicle through active highway traffic to reach the shoulder, which created an immediate and severe safety risk. The vehicle was towed to a Tesla service center in fort lauderdale with only 130 miles on the odometer. Technicians confirmed a "major motor failure" of the rear drive unit requiring a full replacement. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My 2021 Tesla Model Y experienced a critical failure resulting in the vehicle displaying diagnostic code bms_079. After the fault appeared, I was informed that the vehicle's high-voltage (hv) battery requires replacement at a cost exceeding $10,000. As a result of this failure, the vehicle is no longer drivable and has been effectively rendered unusable. The high-voltage (hv) battery management system and/or hv battery pack failed, triggering Tesla diagnostic code bms_079. The vehicle is currently unable to operate due to this fault. The vehicle and battery system are available for inspection upon request. The sudden failure of the hv battery system created a significant safety concern because the vehicle lost its ability to operate as intended. A battery failure can leave drivers stranded unexpectedly, potentially in unsafe locations such as highways, intersections, remote areas, or during adverse weather conditions. The inability to reliably operate the vehicle creates a safety risk for both occupants and other motorists. The fault code bms_079 was diagnosed and confirmed through Tesla's service system. Tesla service personnel indicated that the hv battery requires replacement and that the vehicle cannot be driven safely until the repair is completed. Prior to the vehicle becoming inoperable, warning messages appeared on the vehicle display indicating a problem with the battery system. The bms_079 fault code was displayed, and the vehicle subsequently restricted operation. No warning signs prior. I am concerned that a major hv battery failure requiring a repair exceeding $10,000 occurred on a 2021 Tesla Model Y. A failure of this magnitude on a relatively modern electric vehicle raises concerns regarding battery reliability, consumer cost burden, and potential safety implications when vehicles become unexpectedly disabled. I am requesting that this issue be investigated and that appropriate action be taken to address similar failures affecting Tesla owners.

The vehicle was delivered with a critical safety defect in the braking system and inoperable safety software (gps/fsd/navigation). Upon further inspection by the dealer's own technician, it was confirmed that the vehicle had 'extremely poor brake feel' and 'extreme rust build up' on all pads and rotors, which violated Tesla’s 6mm minimum safety standard for used vehicles. Additionally, a physically damaged windshield harness caused the failure of gps and fsd features. These defects posed a significant safety risk to myself and my family during operation. The dealer has documented and confirmed these safety issues but is now refusing a buyback and is retaliating with storage fees for my rejection of the unsafe product. No warning lights appeared prior to the technician's discovery of the brake defects.

On Feb 25, 2026 my 2022 Tesla Model Y with only 25k miles on it suddenly stopped knowing where it was and almost drove me into a ditch. All cameras stopped working and the gps was stuck in the same wrong location. (service mode showed primary das ecu shows "ap in coreboot" and "status: init. " secondary b shows nominal. Features unavailable. Gnss shows 0 satellites in open sky. ) Tesla service said I was outside of warranty and “there is an internal processor issue with your autopilot system that will prevent updates from installing. The only solution is replacing the computer on April 9, 2026, 12:22,” I had had other computer related issues I brought up during regular service visits but weren’t recorded and I was told software updates would fix such delayed rearview camera upon startup, navigation volume resetting, headlights staying on for extended periods after exit, and lockout issues. I asked Tesla to document the specific failure codes which they never sent. They said “Tesla diagnostics are showing the primary autopilot computer is not booting properly, which is preventing cameras, software updates, and related systems from functioning. Because the computer is not initializing, a firmware reinstall will not complete successfully. At this point, replacement of the computer is the required repair to restore normal functionality. ” my car had a safety recall during its service appointment that they could not install software for unless I paid $3200 to replace computer. I had total loss of rearview camera (fmvss 111 violation) and loss of active safety systems (aeb/fcw), but Tesla refused to repair a federally mandated safety defect if I didn’t pay the full repair cost.
