2018 Tesla Model 3 wheels problems

Hello- I was trying to park my vehicle in a parking spot in santa clara, california when the car automatically accelerated and hit another car. It then immediately had a flat tire. I did not hit the wrong pedal nor was I accelerating it. It was quite dangerous. It came to a halt after hitting another car. Both the cars were damaged.prior to that we had difficulty trying to connect to the car using the app on the phone but thought it could have been due to an app error. Not sure if it was correlated.

Here is a model 3 in the junkyard. [link removed] the cast metal hub assembly on the front rh side has shattered causing the wheel to fall off. This was not the result of a crash, no air-bags have deployed and there is almost no damage to the bodywork. This cracked hub is indicative of bad quality casting and quality control. It is unlikely to be the only such case.
