New Tesla vehicles are experiencing failures with their self-driving computer systems, leading to significant issues. Insider sources reveal that these failures are putting immense pressure on Tesla’s service departments.
The problem appears to be linked to a new version of Tesla’s HW4 (also referred to as AI4) onboard self-driving computer, sometimes called AI4.1. The computers are short-circuiting, though the exact cause is still under investigation. One source suggested that a potential cause is a low-voltage battery short-circuiting the computer during the camera calibration process.
Tesla drivers are reporting failures after driving just a few miles in their new cars, affecting critical features like active safety, cameras, GPS, navigation, and range estimations. Insider sources confirmed that this issue is widespread and affects vehicles built in recent months with the new computer.
Tesla is reportedly receiving a high volume of complaints but has yet to issue a service bulletin addressing the problem. Sources also mentioned that Tesla service is instructed to downplay safety concerns, to prevent customers from thinking their new cars are undriveable.
The issue emerged toward the end of the year, when Tesla was trying to meet a record delivery target to avoid a decline in annual deliveries. It remains unclear if Tesla has reported the issue to the National Highway Traffic Safety Administration (NHTSA), despite the fact that malfunctioning rear-view cameras may violate federal safety regulations, potentially prompting a recall.
Currently, Tesla is considering replacing the computers as a solution, while also exploring a software update to provide a temporary fix. Tesla service is reportedly overwhelmed by the issue, with appointments being pushed into next year.
