Alerts: UI_a020 - Steering Assist Reduced APP_w264 - Lane Departure features unavailable This incident happened suddenly during a normal commute from work to home. It caused the steering of the vehicle to be very heavy and difficult to control which could have potentially led to an unwanted accident on the road. There root cause seems to be a failure in the steering rack component of the car. It is a very common and prevalent issue with Tesla vehicles, and complaints on various Tesla forums and Reddit threads about this same issue. There also has been NHTSA investigations in the past regarding this. The failure caused the loss of safety functionality such as Lane Keeping Assistance, Lane Departure Assistance, Autopilot and FSD. Tesla Service Center diagnosed the alerts as a steering rack hardware failure and is charging almost $5000 to replace the part. …
Driver assistance
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.
On 10-16-21 Saturday around 7:40 PM, I was going to my brother-in-law's house which is on the left side of the road I was driving. It is a single lane road in a busy residential area. I wanted to park outside of the house by the road. I took a left turn towards the gate, then slight reverse and put in drive to pull to park parallel to the road. My Tesla Model-x went into 'Sudden Unintended Acceleration' mode, went left to right to left in a violent way, picking up speed like a rocket. I applied the breaks repeatedly, but the car did not stop and continued to race on the road for about 0.3 mile where the road takes slight left turn. It went and crashed into a 40 ft tall big pine tree at probably more than 150 mph. It knocked off part of the compound wall of the owner, and passenger front tire blew away and landed in their front yard. I had the seat belt on. No other vehicle involved. …
Electrical system
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. …
Since delivery in December 2020 the computer MCU has shut down for two minutes while driving over a dozen times. The computer reboots after a couple of minutes but during this time it disables all instrumentation, turn signals and other driver information. I brought it in to the Tesla Service Center in Highland Park, Illinois with a list of dates and times that it shut down and they told me it was a known firmware issue and that there would be a solution sometime in the future. I don't believe a 2021 Tesla that cost nearly $100 K would force me to stick my arms out the window to make turn signals.
