The mcu that controls the climate and advanced driver assistance systems stops working while driving. I sent a service request to Tesla and they replied that my older mcu1 is failing because of the new software updates. It isn't the emmc card hardware failure, but the symptoms and safety concerns are the same. None of the controls work, as the main screen goes blank and resets while driving. Tesla told me the fix for this problem is to upgrade to mcu2, which they fail to provide for free as a safety recall. There was already a recall for the mcu memory chip failing and causing the same safety concern. The car disables the advanced driver assistance systems when this problem occurs. It happens about once or twice a month for the last year.
The vehicle was involved in an accident due to a failure of the autopilot system. There was a recall letter sent out of 23v-838 a month prior, but changes either did not persist or was the primary cause of the accident.
No early alert before slamming on the brakes, only tapping a rear bumper on a 1999 Toyota tundra. No damage to the Toyota but to my surprise, the insurance company said the Tesla's totaled. The airbags for the driver were deployed only, with no other passengers in the car. Quite a loud noise. I have an edr report, not sure how to interpret it. Did not hear any warning lamps. Fortunately, both the other driver and I suffered no injuries. I would like to find out exactly what happened.
When using auto pilot on the freeway my vehicle sometimes comes to a halting stop for no reason putting myself and passengers in great danger.
