After a software update pushed by tesla, the ap4 computer in my 2024 tesla model y shorted out, causing a complete failure of all safety systems controlled by this computer. The following safety-critical and driver-assist features have become non-functional: 1. Cruise control (adaptive or otherwise) 2. Forward collision warning 3. Lane departure warning 4. Lane keeping assistance 5. Blind spot warning 6. Parking collision warning 7. Full self-driving and auto park features 8. Cameras required for autopilot functionality 9. Auto headlight dim / auto wiper system 10. Back up camera rendered inoperable additionally, because the gps system has failed, the vehicle’s navigation system is inoperable. This impacts tesla’s unique route planning feature that sets up supercharger stops during long journeys. Without a functioning navigation system, i cannot properly plan my travel or locate charging stations, which severely affects the usability of the vehicle. This system also initiates preconditioning of the battery (heats it up to be able to charge), so super charging is extremely slow without the gps system availability. Safety concerns: the failure of these systems, especially safety features like forward collision warning, lane keeping assistance, and blind spot monitoring, puts both the driver and others on the road at risk. Losing access to safety-critical functions after an update is unacceptable and poses a serious danger to vehicle occupants and surrounding traffic. Rear visibility in the car is very limited without the federally required backup camera. Incident details: • the issue occurred immediately following a software update. • tesla pushed the update remotely without providing any warning or indication of potential risks. • the failure appears to be related to a hardware short in the ap4 computer, directly caused or exacerbated by the update.
