1 Adaptive Cruise Control problem

Failure Date: 06/02/2025

While driving our screen shut down, autopilot and gps stopped working and the doors would not open. My kids were stuck on multiple occasions and had to climb through the front seats. Tesla has already confirmed that the driver assistance system ecu (turbo a and turbo b processors) is a known issue. Over 1600 cases reported. This defect disables safety-critical driver-assist functions without warning, which meets the federal definition of a safety defect under 49 u. S. C. § 30102. Provide a free remedy to owners — including replacement at no cost — as required by 49 u. S. C. § 30120. Telsa denied coverage because we are out of warranty. I asked whether the known issue has been reported and why it is not being covered as a known safety defect. Because the problem involves loss of a safety system, it should not be treated as routine maintenance or wear and tear. It is a known safety defect and therefore must be reported and remedied at Tesla’s expense. Tesla refuse to address my concern and would only let me talk to store manager. They told me I had to email business resolutions to get more information. I have not heard back. I was forced to spend $2k to get my car fixed.

2 Adaptive Cruise Control problem

Failure Date: 06/02/2024

This complain is regarding the recent recall regarding fsd Tesla Smart summon failures. Incident date June 02, 2024 car was parked in a parking lot outside a movie theater. I was less than 20 feet away from car with clear visibility, and tried Smart summon. Car pulled out of the parking making an acute turn damaging driver side door, and front bumper of car parked next to it. Tesla was contacted immediately regarding this malfunction of Smart summon and requested them to stop offering this service to owners as it is dangerous. They took 3 months to conduct an internal investigation but refused to share written results. Instead read a generic statement from their website. Still not received a copy of the investigation. Tesla also refused to take take financial responsibility for the damage and their false claim. Smart summon is dangerous and Tesla should not be allowed to advertise.

3 Adaptive Cruise Control problem

Failure Date: 08/31/2021

My sd card failed and had to be replaced on my 2021 Model X. The car's screens went completely blank during the 2021. 24. 3 software update. Car lost all power while park, failed to turn on after 3+ hours, had to be towed to service center. There was told the sd card failed and had to be replaced. This faulty sd card seems to be more than just a 2016-2018 issue.

4 Adaptive Cruise Control problem

Failure Date: 01/31/2021

I purchased a Tesla Model X on 14 Nov 2020 and had been driving just around 2 months. At around 11:10pm or so as we were cruising on the I-580, and were 2 exits north of the 680 highway, the entire instrument cluster in the car which included the large screen and the driver's instrument panel went completely dark. We were baffled as this was something we never encountered before. We began pulling over to the side when after about a couple of mins the lights came on and the panel showed that we had just around 30 miles of range left. We then proceeded to the nearest charging station which happened to be the Tesla factory at 45500 fremont blvd, fremont, CA, 94538. As we reached the charging station we slowed down the car by taking foot off the pedal and was about to change gears to reverse when the car suddenly accelerated without warning and ended up hitting one of the charging stations. The car finally came to a halt after striking and mounting over the charging station. The car struck the charging station head on from the front and around the mid left part of the front bumper. We were all shocked to see that none of the airbags were deployed, even though the collision was pretty nasty. While three of us managed to get away badly shaken and with strained backs, one of the occupants was sitting in the rear and was in the process of taking off her seat belt as the car was slowing down. She was thrown off her seat and suffered injuries to her face. Tesla refuses to ack any vehicle issue and has not shared any accident investigation report.
