Electrical System Problems of Tesla Model Y - part 2

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. 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.

Driver side front window auto rolled back up after pressing the button to once to roll it down. This happened while driving while the right hand was on the steering wheel. The left hand got caught inbetween the window glass and the window frame as it auto rolled back up on its own. It caused bleeding and pain to the left hand.

The contact owns a 2026 Tesla Model Y. The contact stated that the Model Year was advertised with a front trunk emergency release and interior lighting. The contact stated that after purchasing the vehicle, the contact became aware that the vehicle was not designed with the front trunk emergency release or interior lighting, which the contact considered a safety issue and a violation of fmvss no. 401. The Tesla service center was contacted and confirmed that the Model Year and other vehicles were no longer designed with the missing parts. The manufacturer was notified of the issue. The failure mileage was approximately 570.

Vehicle information 2025 Tesla Model Y approx. 30,000 miles purchased new ~11 months ago incident description while driving at highway speed, the front trunk (frunk/hood) of my 2025 Tesla Model Y unexpectedly opened. The hood immediately flew upward, flipped backward over the windshield, and shattered the windshield. The frunk had not been opened in approximately two weeks prior to the incident. The vehicle had not undergone recent service or repair involving the hood or latch assembly. There were no prior warnings or alerts indicating that the frunk was unlatched or not latched properly before driving. The hood appeared fully closed prior to the trip. However, after the incident once we pulled over, a bolt was completely out of place, as shown in my video. Even if the primary latch was faulty, the secondary latch / catch should have prevented the hood from opening all the way and slamming the windshield. This failure to notify improper latching created an immediate and total obstruction of forward visibility at highway speed and posed a serious crash risk. The vehicle has approximately 30,000 miles and is less than one year old. Given Tesla’s prior recall related to hood latch detection issues, I am concerned that either: •the latch system failed mechanically, and/or •the vehicle failed to properly detect and warn of an unlatched hood. This is a significant safety event and could result in serious injury or death if it occurs in traffic.

While driving, the vehicle displays a critical “air pressure in tires very low — pull over safely” alert. When I pull over and inspect, the tire pressure is normal and there is no flat. The alert clears on its own after driving a few more miles. The vehicle has been serviced four times for this issue between February and may 2026 at Tesla service centers in austin TX, flower mound TX, san diego CA, and los angeles CA. The tire pressure monitoring sensors have been replaced three times (rear left twice, front left once). On the may 7, 2026 san diego service visit, the technician documented the root cause as a low voltage issue with the sensor system. The issue continues to recur after each repair. A false critical safety alert that instructs the driver to pull over creates a safety risk because it trains drivers to distrust real alerts, and pulling over on highways carries its own risk.

The vehicle display flashed red and then the vehicle turned off completely while in traffic with no ability to change gear, operate the electronic door releases, or turn the hazards on. Safety was put at risk because insufficient notice of failure was given so it was impossible to get out of traffic, the vehicle could not be put in neutral so could not be pushed out of traffic, further the hazard lights could not be turned on so I had to stand in traffic waiving people around the vehicle. Because the electronic door releases didn't work, the doors could not be opened from the outside, had a front window not been open, it would have been easy to trap our child in the car. The dealer confirmed that the failure took place from vehicle logs but was unable to reproduce the problem. The dealer/manufacturer inspected the vehicle. Prior to this happening the vehicle showed warnings that power was reduced and vehicle may not restart about 20 minutes prior to the event, but the warnings disappeared after a minute. Even though Tesla confirmed the failure, they refused to diagnose the problem or fix it so the vehicle remains dangerous.

Tesla Model Y 99,000 km it is known issue with many driver of same model and milage that wire harness connected to oil pump gets hot and damage. This can also cause fire. Many people have been complaining about similar issue on facebook group.

Vehicle experienced pcs (power conversion system/DC-DC converter) failure, rendering it completely undrivable—no 12v power, cannot charge or start. Pcs is physically integrated inside high-voltage battery pack per service manuals. High-voltage battery warranty active (8yr/120k miles). Tesla service denies coverage citing "associated component" in vague emails—provided only general warranty table, no specific exclusion language despite repeated requests for exact quote/formal written denial. Escalated to managers: offered "view-only" internal service bulletin on screen at meeting—no print/copy/photo allowed. Explicitly refused formal written denial letter.

All safety and most computer related features in the vehicle have failed. Cruise control, backup cameras, all other cameras, the navigation (assuming this is also impacting the projection of remaining battery life as my car always thinks it is at my home), warning signals for approaching obstacles/dangers, cruise control of any kind does now work, lane departure warning has failed, and automatic windshield wipers do not work. This happened without warning and was not related to an update. On January 13, 2026, the car worked in the morning and then all of these issues started happening. I made a Tesla service appointment, but they are not able to see me until February 3, 2026.

Observed intermittent center display/infotainment computer (mcu) crashes/reboots where the center display becomes blank and then restarts. In recorded events, when reverse was selected during an mcu reboot interval, the rearview camera image did not display until the reboot completed. Recorded rear camera unavailability during reverse was approximately 10–17 seconds. Mcu crash/reboot behavior was observed to be repeatable, including predictable occurrence while the vehicle was in the built-in service mode. After a factory reset, repeated/double boot behavior was also observed. Additional observations: - with the turn signal activated, light leakage was observed in the side repeater camera image (glare/bloom present in the camera view). - with each windshield wiper sweep, the forward camera image was observed to briefly flicker to a purple/green distorted state and then return to normal. - during driving, the on-screen message “auto lane change unavailable” was observed. A separate rear camera symptom has also been observed: intermittent freezing/stale frames (image appears not to update). This rear camera freeze behavior has not yet been captured on video. These conditions have been documented by video/screenshots and reported to the manufacturer/service center for inspection/diagnosis. No crash or injury occurred. The vehicle is currently located at the manufacturer’s service center and is available for inspection upon request.

I got into my car two days ago and the computer screen was black. I have tried everything to reset it, holding down both scroll wheels with the brake pressed for up to 2 minutes, unplugging the low voltage battery overnight and plugging it back in, and even doing the hard reset at the disconnect under the rear passenger seats and my computer will not turn on. I can't see any information about my speed or how much charge I have, I can't turn on climate controls and it's the middle of winter and I live in the mountains of colorado. I can't even open my glove box without the screen. From everything I read, it sounds like an mcu failure, my vehicle has the newer mcu2. Tesla quoted about $800 for a tow and it sounds like the replacement costs could be $2500+.
