NHTSA Complaint #11693127 — 2021 TESLA MODEL Y

I was driving along one of the main highways in Orlando, Florida called [XXX], on Wednesday [XXX], in my Model Y Tesla. I was between the exits of [XXX], and [XXX]. I was in the middle lane. There was a software update issued the previous Sunday. The warning came on the display that the lane changing was not valid. At that point the car took over and accelerated. The brakes would not work, until I slammed on it after 3 times, and the car began to decelerate. The air conditioner went off, along with the electrical turn signals. I as able to get off at the [XXX] exit for it is a bit of a "hill" up in Florida, but knew I could coast into a lane hopefully no one would be in. I was able to at least coast into a parking lot, and bump the car into a concrete barrier, and a tree infront of the barrier. The car would not respond to park, neutral or the emergency brake. I tried re-booting the car 3 times and nothing. I had to call a tow truck to tow to the Tesla Service Center in Clermont, Florida. They could not get it in park either and had to drag the Tesla onto the flatbed. After 5 days of not responding to my text, I walked into another Tesla service center to plead my problem. Long story short, there is an unexplained anomaly that is in the CANBUS and cannot duplicate the error. More $ to have to tested for another week. They gave me a loaner to use, a Model S. After a few days driving it the loaner screen went blank and I was stranded. I had their loaner towed back to the service center. They will not 100% address the problem. They know it is in the CANBUS system, but now I definitely am scared to drive the car or get it back. How do I know if they will really tell me it is fixed? I fear if I get back in the car.
