1 Assist problem

Failure Date: 06/30/2025

I was driving down the road and my car started shaking, I was about 5 or 6 miles from an exit so continued and within 1 mile a rod broke and fell on top of my tire causing me to catastrophically have to stop n swerve off the road in 5 o'clock traffic. I just purchased this car 3 months ago, no issues just happend all of sudden. There are reports of weak suspension parts for Tesla specifically the Model X and y. The suspension parts need to be recalled. I was very lucky to not have collided with another car and potentially causing a fatality.

Our Tesla Model X is failing recently with several issues as listed below: 1. 'autiopilot disabled' - autopilot was not available to use since 09/2024 after upgraded to 12. X fsd upgrade. Tesla service diagnosed in 11/2024 with some error connected to evaporator fan, advised me to replace the kit at an estimated $580 2. 'unable to start' - hv battery failed on 03/06/2025 with series of failures that was reported to NHTSA (voq#11651899). Tesla replaced the battery, and service delivered vehicle on 03/24/2025 3. 'hood unlatch' failure - while driving home from service center on the same day at 70 mph on I-95 freeway, the 'hood' popped up blocking the front view, and had to pull vehicle to shoulder to safety. There was no warning message on the screen at all. Took the vehicle to service immediately, and service team pointed that they forgot to turn on 'auto-latch' resulting hood failure. They offered the 'free' repair of hood. 4. 'ecu autopilot failure' - while taking the delivery of 'hood' fix on 04/22/2025, I noticed the 'autopilot' was still not working. Serviced diagnosed with 'failed autopilot ecu' at an estimated cost of $1791. 55. Currenlty the vehicle is with Tesla service team. My vehicle is with service team since 03/06/2025, and has been identified with series of issues/failures. It has caused severe safety failure putting our lives at risk with 'unlatched' hood while driving on a freeway. Also with hv battery failure its completely unreliable on when it might fail during driving. Now with failed autopilot ecu, we are unsure of the vehicles ability to navigate, drive function and safety concerns. Service team is unable to provide precise root causes or fixes, or restore it to a functioning vehicle. Every visit with service team there is a new issue with vehicle. Our family is greatly concern with the quality of the vehicle, persisting issues, safety concerns and overall reliability of the vehicle. Please find enclosed all service records.

3 Assist problem

Failure Date: 11/07/2023

The full self driving system failed to operate correctly. This caused my car to hit another car. I have asked Tesla for the data they use to tell what the driver was doing when the system was on but the Tesla staff who respond to my requests plead ignorance of what data I am referring to. I am not ready to spend the money it would cost to hire a lawyer to force Tesla to hand over the data from their system. I have video from the Tesla camera showing what happens. I will try to upload it. Here is a quick run through of what happened: I entered the freeway and got into the left lane. Once I was safely in the left lane and up to speed I turned on the fsd keeping my hands on the steering wheel. After a few moments the car veered to the right, I tugged against the pull of the fsd and got it back in the lane when all of a sudden it turned my wheel hard right into a minivan. It happened so fast that the wheel turned even with my hands on it. I have been trying to talk to someone at Tesla but it is difficult to break through the front lines as they deflect contacts away from anyone who might be able to answer my questions about getting the fsd incident data. The video is . Mp4 so it is not allowing me to upload. Please let me know how to send you the video.

4 Assist problem

Failure Date: 10/26/2023

On oct. 26 at approximately 5:45 p. M. On hwy 26 near sandy, or the autopilot system failed by abruptly turning the car into the upcoming turn lain (marked with solid white line) and towards oncoming traffic. I had to immediately take significant corrective action to move the car back into the lain I was traveling. I firmly believe that the car could have cross into the lane going the opposite direction. I definitely was very unsettled by this event. This type of spontaneous autopilot error has occurred numerous times in the past to me (have driven a Model X Tesla since 2016) and I now very seldom use the feature while driving. I have taking no further action regarding this event or others because while under warranty Tesla always come up with rationale that they couldn't find a problem because of loss of connectivity, could not detect a problem, etc. I thought that through the years with their hype and over-the-air updates things would get better but they have not! thank you for your time. John.

5 Assist problem

Failure Date: 04/09/2022

While driving at speed approximately 4:20pm est April 9th, 2022 on i95 near the georgia/south carolina border the onboard computer froze and became unresponsive, including the speedometer, the radio, navigation system, etc. . I became aware of the issue because the car started to slowly slow down but the display continued to show 70 mph. I forced the computer out of autopilot but the car continued to show it was in autopilot. Shortly after the display behind the steering wheel went blank then rebooted, followed by the center console. Thankfully I was paying attention and did not panic, had I panicked I could very easily been in an accident as I did not know what was going on with the car. I reached out to Tesla multiple times following the incident and the agents and agents were non-caring and treated it as no big deal, and acted as if I should not be concerned about it. I could not even get assistance from them on getting service for the car. They kept pointing me to the mobile app on the phone which would not function properly and after typing the incident into as I wrote above 3 times I gave up.
