Tesla has told me the AP4 computer has failed in my car which has resulted in them having to replace it. I had this issue start on 1/12, and I scheduled the earliest appointment available for 1/30. They did not offer me a rental or any assistance during this time, and I need my vehicle to commute to work and conduct other essential activities. It has just over 1,000 miles on it and is ~3 months old now. This issue impacts: backup camera, emergency braking, blind spot detection, lane keep/centering, assisting with parking, automatic high beams and wipers, cruise control/ adaptive cruise control, Vehicles built in GPS to be stuck at one location every time, has made my touchscreen not automatically brighten or dim, my auto dimming mirrors be too dim in most driving conditions, constantly fail to install system improvements and safety updates, and because my vehicle keeps trying to do this, it has caused increased battery drain as well. This has increased the safety risk of my vehicle tremendously, and i have received no reparations for it.
