1 Adaptive Cruise Control problem

Failure Date: 03/05/2025

I was driving my car on the freeway on cruise control, when there was a sudden/automatic violent break of 65 mph to 0 mph. There was no car in front of me, and there was nothing above my car (no direction sign, no bridge, no fastrak billboard, nothing). This was a "phantom break" and it was violent and sudden. Tesla needs to fix this!.

2 Adaptive Cruise Control problem

Failure Date: 09/16/2022

Have experienced phantom braking at high speeds which could cause a rear end collision involving the vehicle or vehicles behind me. The phantom braking occurs about once per 500 to 750 miles and always occurs while traveling on the freeway at 60 to 70 mph. Approximately 80% of the time, it occurs at exactly the same place just before a large freeway sign. The occurrences are regardless of surrounding traffic. Sometimes it occurs with many other cars (at safe distance from me), sometimes with a few cars around me and sometimes with no cars within 100 yards in any direction. This one location is located in mid-California, at the north end of ventura, on us 101 (freeway) northbound about 200 yards south of the highway 33 (ojai) cutoff.

3 Adaptive Cruise Control problem

Failure Date: 06/12/2021

My car has severe phantom breaking due to adaptive cruise control. When I use my Tesla's cruise control on the freeway, on a complete flat straight away that has no vehicle in front of me, no sign/bridge in front of me, and no items/object in front of me, my vehicle while randomly/violently slam on the break violently hurling me and all passengers in my vehicle forward. This is even more dangerous when there are vehicles being me in close proximity who could easily could have rear ended me all those times. I am forced to not use my cruise control due to these dangerous conditions.

4 Adaptive Cruise Control problem

Failure Date: 01/08/2021

The entire screen went black and it started showing the backup camera. I couldn't fix it even by restarting it. Notifications included- center display unavailable, it also affected the turn signal while driving and cruise control. Other safety features of the vehicle were also unavailable.

5 Adaptive Cruise Control problem

Failure Date: 01/08/2021

In 2019 my main computer screen went blank. And didn't come back on. I was able to drive but had no defogger or other safety features. Tesla replaced an mcu computer module. It happened again in 2020. I brought it back January 14 2021 and instead of replacing the unit with a 64 gb unit (the original was a 6 gb unit) they emptied out some information to make more room. I see this as a temporary fix. I am not confident this won't happen again. My car is still under an extended warranty.

Manufactures known defective mcu 1 defective memory housed in daughterboard and screens leaking adhesive in the driver's instrument cluster and 17" screen on mcu, adhesive dripping down onto cabin area .
