In January my parents Tesla in self driving mode drove them straight through a building. The breaks didn't deploy, the airbags didn't deploy and the steering wheel was shaking and unresponsive. Thankfully no one was seriously injured. That said, there was a lot of physical damage to the restaurant/building and the car was completely totaled. We are certain that there were catastrophic failures with the car that caused the accident however the mechanic has informed us that due to her NDA she cannot provide any details about her findings after examining the car. She sent her findings to Tesla who was supposed to issue a report to us and the insurance company, but several months later we still have not received anything. They are well past the 30 days time limit. We cannot get anyone from Tesla to respond to us. There was a police report and the cops, firemen, and mechanics where all absolutely floored that the airbags didn't deploy given the damage to the vehicle. Self driving failed. Breaks failed. Steering failed. Airbags failed. and Tesla has failed to respond.
