I sent following to Tesla I had an accident at around 6:30 PM on Sunday, March 2nd with my Tesla Model 3 and asking to see if you can conduct a diagnostic check into this incident. I was coming home at that time with the Tesla and about 100 yards from my house, I experienced a sudden acceleration with the car going from about 20mph to, I think, over 40 mph and crashed into the garage area of my house. Around the time I started experiencing that unwanted acceleration, I heard a whining sound. As it started that sudden acceleration, I checked below to make sure my right foot was pressing on the brake pedal and it was. Since I have the regenerative braking with my tesla, the car should have decelerated but, instead, it sped up. I continued to press the brake pedal but I could not mitigate my cars continual acceleration. It eventually crashed through the lowered garage door and went through the right side of the garage wall about half way out and came to the stop. I was driving myself and not engaged in self-driving feature. I like to see if the Tesla has any resources available to retrace last few seconds and be able to glean more information of why that sudden acceleration might have happened. The car is still located in my garage but currently the car is disabled and powered off. The cars power was on and it automatically turned on emergency light for about 30 minutes after the accident before it eventually powering off. I am also curious to know why none of the airbags were deployed in this accident. I have many photos available of the accident. The fire department and police came and assisted. I do not know if this matters but the couple of nights before the car had one of those over the air updates by Tesla and also about couple of minutes before the accident I drove through about a minute of hard rain in otherwise light rainy drive. I also wonder why auto-braking did not engage against the house.
