In July 2024 all the cameras on the Tesla Model S except the rear stopped working after a failed software update. This meant that all of the driver assistance systems as well as GPS, adaptive cruise control, blind spot monitoring, lane departure warning, forward collision warning etc stopped working. The lack of availability of this system meant that the car no longer had any advanced safety features that came with the car. It took many months for Tesla service to diagnose and fix the problem, which they identified as a failure of the Auto Pilot computer. After I was finally able to get an appointment with the Service center, they replaced the Autopilot computer at a cost of over $1500. The failure first appeared in July 2024. The symptom was GPS location being stuck and Autopilot and all safety features being not available.

On freeway in traffic, autopilot is enabled. Vehicle is running perfectly fine in start stop traffic slowing down and speeding up as needed. Traffic starts to clear up, and as vehicle speeds up, there is a sudden slowdown again. Instead of braking/slowing down, autopilot turns off without an additional audible alarm (just the standard sound for turning off autopilot), instead the forward collision warning alert goes off. Able to brake in time to prevent accident.

I drove to work on may 2, 2019, and was trying to park in my allotted parking stall on the 3rd level of my office parking garage. My parking stall was along the outer edge of the garage and the only barrier to the outside was a set of three (about " diameter) cables strung between outside columns of the garage, besides a thin perforated corrugated metal sheet outside the cables, acting as a rain stop. I was trying to slowly turn right from the parking aisle to park between two pickup trucks on either side of my stall. When I had turned partway into my stall, my tesla suddenly accelerated into my parking stall at high speed, hit the outside cables, rebounded backwards and stopped about 10 feet from the outside cables. The cables saved me from plunging 3 floors down from the garage. There was extensive damage to the hood and front portions of my tesla. There was also some damage to the metal corrugated sheets outside the cables and a slight dent on the corner of the vehicle parked to my right. I have been parking in my office parking stall for about the past six months without any issue like this. I want to know why my car accelerated like that without warning and why the collision warning system was not triggered by the outside corrugated metal sheet. Also, there was an issue with my tesla the previous evening. When I tried to start my tesla after work, I got the 'systems are powering..' message on the screen and my car would not start even after a long wait. Then, I had to google to find a way to reboot the car computer, by pressing two buttons on the steering wheel. On the day of the accident, I used the intermittent rain sensing wipers for the first time, as there was a light rain. My car is still in the body shop waiting for some back ordered parts. I have asked tesla to do a diagnostics to see if there were any software bugs in the system.
