1 Warning problem

Failure Date: 12/03/2025

Critical safety failure: loss of driver override and extreme hmi/signaling latency. 1. Loss of override & unintended acceleration: while operating fsd (supervised), the vehicle ignored a 65 mph set-point and accelerated to 80 mph. I attempted to reduce speed by pulling down on the steering stalk 4-5 times, but the vehicle ignored all manual inputs, requiring a hard disengagement. 2. Lane departure / path failure: the vehicle failed to maintain lane centering, specifically crossing over the centerline into opposing traffic. This occured without warning or system-initiated steering alerts 3. False signaling / path failure: I’ve seen at least two occurrences where system exhibits dangerous signaling conflicts, such as activating a right-turn signal while simultaneously executing a left-turn maneuver. One time it was on a 45–55 mph rural corridor where trailing drivers frequently overtake slower vehicles. A false right-turn signal acts as a dangerous "all-clear" for a trailing driver to pass on the left, creating a high- probability broadside collision scenario when the Tesla physically executes its left turn. I have no idea if this has occurred more than these two times as I don’t check this. The other time I caught on video, by chance, as I was trying to capture the surging behavior to show the Tesla service center 4. Audio & visual hmi latency: audible instructions arrive 100+ feet after turns, and the map ui auto-zooms away from the driver’s focus, requiring constant manual screen contact to view street names. This forces significant visual-manual distraction. 5. Confirmed inadequacy: Tesla service invoice #[xxx] (Jan 27, 2025) documents: 'the current computer is a little too slow for full self driving function. . . ' confirming the hardware is unfit for safety-critical processing. This incident is directly relevant to NHTSA investigation pe25012. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

2 Warning problem

Failure Date: 06/05/2025

While merging onto the highway an error message showed up on the dash stating "steering assist may be reduced" upon immediately after the steering froze and could only be moved slightly using significant force. Approx. 75lbs. I am athletic and work out and had trouble moving the car to the side. If my wife or daughter had driven the car they would not have been able to steer and this could have caused a significant accident, injury or death. Upon pulling over, I rebooted both computers on the Tesla Model S 75 d and the problem went away. I immediately drove to the Tesla dealer in chesterfield, mo. There they seemed unconcerned, and advised me it was likely just a firmware issue and wouldn't be able to look at the car until the next week. I was shocked. Since the systems seemed to work I drove home and parked the car. On the driveway, the same error showed up and steering seemed again to lock up. After rebooting problem went away. Looking at the Tesla forums this seems to have happened before and poses a serious danger to the driver, occupants and fellow drivers on the road. I no longer feel safe driving the car.

3 Warning problem

Failure Date: 03/18/2024

I received a safety recall dated 2/8/2024, recall no 23v-838. Tesla has failed to remedy the defect & claims a remedy is not necessary. Specifically, I took my vehicle to Tesla on 3/18/2024 to update vehicle software to incorporate additional autosteer controls. See attachment: "repair notes: "no update necessary", despite the vehicle running a software version less than 2023. 44. 30 as specified in the recall notice.

4 Warning problem

Failure Date: 07/14/2023

1. Previously listed recall has been erroneously removed from recall history for my VIN. . Read more...

5 Warning problem

Failure Date: 03/31/2023

The car, which was equipped by Tesla's full self-driving beta software v11. 3. 3, attempted to make a premature left lane change in preparation for a left turn at the light, which almost put me in front of a pickup truck waiting in the center turn lane.

6 Warning problem

Failure Date: 05/08/2021

My Tesla Model S has the v1 hardware, also known as mcuv1, with the daughterboard emmc replacement from the previous recall running on firmware 2020. 48. 37. 1. The sound for the entire car will cut out. It might come back, but even a reboot of the car does not solve anything. These sounds may include blinker noise, speed limit chimes, lane departure warning, autopilot engage/dis-engage chimes, gear warnings, collision safety chimes, early braking warning, and a lot more safety-related sounds. This happens every time I drive the car, not just the reported date. I have brought it in for repairs numerous times, but this has never been addressed. I am only told to wait for a new firmware upgrade, which I have been for years now since I first reported the issue to Tesla. This only happens with mcuv1 cars and they have refused to provide a free hardware upgrade even after my incessant reports and appointments stating that it is unsafe.

7 Warning problem

Failure Date: 01/08/2021

My screen keeps freezing and is black causing a safety hazard and I can't drive the car anymore. I have taken the car to Tesla several times but they won't fix it. The computer is broken and the chip has failed. The ac doesn't work, I can't control my radio, my back up camera doesn't work, turn signals don't work, hands free system doesn't work, nav system doesn't work. Tesla needs to replace my entire nav, entertainment computer to return the car to what I actually paid for. The clock doesn't work, and I can't tell how much battery life I have left. This is a dangerous situation and they have refused to repair then computer. This is an electric car and 100% relies on the computer to control even the smallest details. I cannot drive the car and try to reboot the car while I'm driving. Nothing has worked. Tesla knows about this situation and I am not the only owner who has this problem.

8 Warning problem

Failure Date: 08/07/2020

Large middle screen goes black which controls all the uses of the car. The car runs, but there is no navigation, no radio, no heat or air conditioning. It is very scary!!! it has happened a number of times since 3/2020-1/2021. I had the car checked in November 2020 and asked to have the mcu replaced, but they said there was no recall and it wasn't necessary. Also there is a yellow edge on the screen. I didn't think to take a picture, but will the next time it happens.
