My Tesla Model Y experienced a complete computer failure, rendering all active safety systems inoperable. This included backup cameras, speedometer display brightness, and collision avoidance system. After receiving assistance from Tesla service, the issue was diagnosed as a shorted computer. A computer replacement was performed, resolving the problem. I am submitting this case as a reference for potential investigations.

Bought my Tesla Model Y on [XXX]. Exactly one month later on [XXX] I start my car to find that none of the cameras are working. This means Autopilot, cruise control, rear camera, blind spot monitoring and many more safety features are completely down. In addition the GPS does not function meaning my car is not trackable and Maps don't work, another safety concern and main reason we bought the car. This is a widespread issue that Tesla Service Centers have been informed about from Tesla that it is a bad computer that needs to be replaced - in a 1 MONTH old car. My only option is to wait for a computer to be assigned to me which is at earliest on January 21st of 2025, almost 6 weeks without a fully functioning brand new $46,000 Car with only 1400 miles on it. Tesla are also unwilling to make any kind of restitution such as a loaner car, or a refund for the Full Self Drive and Connectivity packages I just purchased but cannot use as my car is broken.

Cameras not working with latest Software update on November 26th. without even inspecting the car in-person, Tesla service agent told need new AP4 computer on 2024 model Y which is 1 month old . I think Tesla knows about this issue and there is lot of wait time for getting the AP4 computer. Tesla service advisor states - car is totally safe to drive with just mirrors till appointment in few weeks. As per the federal safety agency, if a car is not having a backup camera, that is a safety violation and there are lots of Tesla vehicles driving without backup cameras. No backup camera, navigation, battery life dying faster. It seems like a liability to me to drive this way and very negligent to me.
Tesla has told me the AP4 computer has failed in my car which has resulted in them having to replace it. I had this issue start right around Thanksgiving. I scheduled the soonest appointment available for 12/16 however Tesla contacted me and moved my appointment because they stated that the part was unavailable at this time and should be delivered by 01/20/25. Not offering me a rental or anything on my brand new '24 Tesla. It has just over 1,000 miles on it and is ~3 months old now. This issue impacts: emergency braking, blind spot detection, lane keep/centering, assisting with parking, automatic high beams and wipers, cruise control/ adaptive cruise control, Vehicles built in GPS to be stuck at one location every time, has made my touchscreen not automatically brighten or dim, my auto dimming mirrors be to dim in most driving conditions, constantly fail to install system improvements and safety updates, and because my vehicle keeps trying to do this, it has caused increased battery drain as well. This has increased the safety risk of my vehicle tremendously... Tesla has not seemed to publicly acknowledge the issue yet either.
Vehicle cameras stopped working. Navigation stopped working. Screen also stopped working for a time. Was able to get it back on but it went off multiple times since. If I can't see the screen, I can't tell how fast I'm going to do anything else. Cameras control many of not all of the safety systems. So those are all inoperable. Issue is being reported across multiple forums all over the internet as "short in ap4 module."
The computer is not working which connects to the forward collision warning system, navigation, and all safety when it comes to driving. I am still waiting to hear back from Tesla about the problem and haven't had a resolution.
The contact owns a 2024 Tesla Model Y. The contact stated while driving at an undisclosed speed with Full Self-Driving Assist Mode activated, the vehicle inadvertently veered off the road, drove over a curb and came to a complete stop. No warning lights were illuminated. The contact stated that the vehicle then operated as needed; however, the failure recurred several times while driving. The manufacturer was not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 3,000.
Since I purchased the car 4 months ago my car has been going into the service center non stop for every issue you can imagine. Tesla spins and blames all issues and ignores me. Corporate says they can’t do anything and then ignore. Service center providing inaccurate or not providing service invoices.Deny my buyback requests. Repairs are failed and new damage occurs at every service appointment. New issues arise with the car every time I drive it. I rarely drive it as it’s not safe. Tesla continually cancels service appointments or does not have parts in stock. issues: -Safety restaurant system fault -electric motor issues: loud high pitched whistle/whine when driving. -car loosing power while driving -seat moving while driving -window clicking -water dripping out of dash vents. -Misalignments: frunk, trunk, trim -paint drips, bubbles, cracks, peeling -battery range issues -battery coolant fan issues -defects interior plastic surfaces -seat defects -hole left in front of car between dash and windshield with damages windshield. New dash uneven over airbag. -plastic trim falling off
All safety features and cameras on this vehicle are currently disabled. Specifically, the following functions are not operational: Forward and parking collision warnings, Blind spot warning, Lane departure and lane-keeping warnings, Rear cross-traffic warning, Self-driving capability, Adaptive cruise control, Navigation system, Location tracking, Sentry mode, Premium connectivity features, Reverse camera, Front and side cameras. Additionally: the headlights remain on continuously during daylight hours. The interior control panel screen and the side and rear mirror displays are stuck in night mode.
The car randomly restarts while driving and some functionalities doesn’t work like turn signal, ac, radio, headlight. It could lead to the accident. I reported to Tesla and they said it is fixed with reset. It is still happening.
With beta self driving engaged, I turned south on [XXX] intending to turn west on [XXX]. At [XXX], there are 2 right turn lanes. I approached the intersection turning from the left lane. Rather than turn right, the car continued straight. I was able to manually override the system and luckily brought the car under control; otherwise, I am sure I would have ended up in a very bad spot. Later the same day beta did not recognize a turn lane into my community but rather proceeded straight. I have since disabled the beta FSD. I am responding to today's CNN article of your pending investigation. I cannot respond to your other questions above. Thank you!

The contact owns a 2024 Tesla Model Y. The contact stated that while at an undisclosed speed, the vehicle had accelerated independently. No warning lights were illuminated. On another occasion, while exiting a parking lot the vehicle unintendedly accelerated causing it to crash into a parked vehicle. The vehicle came to a stop partially sideways after it drove over the parked vehicle. The fire department arrived on the scene and safely removed the contact from the vehicle. It was unknown if a police or fire department report was filed. The contact sustained minor bruises on the right arm and sought medical attention a day later. The vehicle was towed to an insurance lot where it remained for further inspection. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was unknown.
Component Failure: Coolant line and connector to battery pack under Tesla Model Y failed, causing vehicle shutdown. Part available for inspection. Safety Risk: Driving on mild dirt road, vehicle experienced progressive issues leading to sudden shutdown. Potential for serious accident, especially at higher speeds or in traffic. Problem Confirmation: Tesla service center confirmed coolant leak from damaged connector caused shutdown. Reported as known issue that requires complete battery replacement, despite it just being a connector. Inspection: Examined by Tesla technicians. Further inspection possible if required. Warning Signs: Screen displayed progressive warnings: 1. "Coolant low, schedule service, but okay to drive" 2. "Power reduced, okay to drive" 3. "Rear motor disabled be careful going down hills" 4. "Pull over immediately" - followed by shutdown Additional Details: - Small rock likely hit connector on dirt road - Coolant connector not threaded, not easily replaceable - Common issue in Tesla models, especially Model Y - Warnings progression didn't adequately convey severity - Battery replacement cost exceeds $15,000+, unreasonably high given Tesla's practice of refurbishing and reusing batteries Recommended Action: 1. Redesign coolant connector for impact resilience 2. Implement threaded design for easier replacement of connector (not entire battery) 3. Replace plastic shielding under vehicle with 1/8" aluminum shielding 4. Significantly reduce battery replacement costs, considering Tesla's ability to refurbish and reuse batteries This single point of failure poses significant risk and potential for extreme repair costs. Coolant connector vulnerability to minor impacts suggests design flaw affecting Tesla owners driving on unpaved surfaces. the federal safety agency investigation needed to prevent future incidents, ensure safety, and address unreasonable repair costs for Tesla Model Y owners and other road users..
I was on [XXX] heading towards Chicago and following the traffic. I started changing the line to pass the vehicle in front of me and suddenly my tesla completely lost control and started drifting to the sides. I released the accelerator right away but it made it even worse. It seems that acceleration continues to happen that’s what made car to drift. Eventually car slowed down and I was able to make it to my line. I don’t understand why line assistance didn’t work to keep the vehicle stable, why after releasing accelerator the vehicle continued to gain the speed. It was sunny day and dry road. No foreign objects on the highway. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The Tesla accelerated by itself while I am driving in a heavy traffic. To avoid hitting the front car, I braked several times, which didn’t work at all. It still accelerated, instinctively I steered wheels to the right front and hit a small hill. Airbags are out. I struggled to get off the car and shouted for help. 911 was called and emergency ambulance took me to ER. Luckily I am alive, it could be much worse that I would tremble when thinking of that crash scene again. This happened on [XXX]. I am waiting for the report from the police and the next steps from Tesla Insurance. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The contact owns a 2024 Tesla Model Y. The contact stated that the vehicle was experiencing abnormal battery drainage and was not operating based on the designed mileage. Additionally, the contact stated that the vehicle was overheating, and the failure persisted after the vehicle had been parked and turned off. The contact also stated that the front passenger's side window would roll down unintentionally while driving. There was no warning light illuminated. The vehicle was taken to a Tesla Service Center several times; however, the failure could not be replicated. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 6.
The vehicle would not stop and ran into the back of a friend. I am not safe in the vehicle as we were in a parking lot no way I could’ve reached top speed.
I purchased my Model Y with the Tow Package. We used the trailer for the first time. There was no 12v auxiliary power to the trailer. The 7 pin trailer connection is incomplete. Post purchase, we found Tesla purposely disconnected the 12v accessory power pin when they switched low voltage systems in the 2022 model year rather than add the necessary power reduction part to send 12v power to the trailer. This is a serious safety issue because the 12v accessory pin on the trailer connection is the used to maintain charge on emergency trailer surge braking systems (engages trailer breaks if the trailer disconnects from vehicle). This known safety hazard was not conspicuously communicated before purchase. A notice does not appear on the Model Y Tow package page (attached). This is very uncommon and unexpected for manufacturer installed tow packages with 7 pin connectors to leave the 12v auxiliary power disconnected.
The battery coolant started leaking when we connected the car to a supercharger. After charging a low coolant warning came up on the screen, but the message read “OK to drive”. Started driving home when more alerts came up “Power reduced” and “Speed limited to 68 mph” but still showed “OK to drive”. About 30 miles later the screen abruptly shut down on the freeway. Was able to pull over to a stop on the shoulder and call a tow truck. Screen never came back up even after attempting to restart, car is now at the service center. There is a pump that has continued running for over 2 days without stopping. The interior lights turn on and off every 30 seconds. There has been no damage from road debris or anything else to this car. The vehicle only had ~350 miles on it, and we only had it for 3 days before it malfunctioned. The screen displays vital information such as speed, turn indicators, and so on. Without the screen being on it is not possible to safely operate the vehicle.
The contact owns a 2024 Tesla Model Y. The contact stated that after downloading the software, upon engaging the Auto Pilot, and driving approximately 35 MPH, the vehicle crashed into a curb. There were no warning lights illuminated. There were no reported injuries. The vehicle was taken to the local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was contacted but did not assist. The failure mileage was approximately 1,024.
Electrical system had 7 alerts/warning scroll on screen. Said vehicle was going to shut down. Regenerative braking system failed. Pulled car into a parking spot. Vehicle would not go into park so I could not take foot off of brake. Started to shift between park and neutral randomly. Was told by Tesla to reboot car. Did this three times, but nothing changed. Tesla dealership reproduced and confirmed. There were no warnings or messages before the incident.
Unknown. Drove car in front of garage. Car came to a full stop. About to put car into reverse from drive in order to back into the garage, when car suddenly accelerated forward. Turned wheel sharply to the left in order avoid hitting neighbors fences. Vehicle traveled in an arch and collided with a tree next to an fence and stopped.
