NHTSA Complaint #11555372 — 2020 TESLA MODEL 3

I was already situated in the left turn lane on a two way city street, slowing down, and about to come to a full stop before making a U turn when I felt a surge in power before the car picked up, accelerated uncontrollably, and launched forward. In front of the turn is a raised cemented median strip divider where the car hit and went on top of it. Instinctively, I just held on to the steering wheel firmly to keep the car straight so that it will stay on (top) and within the divider and not veering to the right or left and running onto incoming traffics on both sides of the street. The car came to a stop after coming off the other end of the divider (approximately 100 ft) and ended on one of the lane from the opposite traffic. Thankfully there were no cars on that lane at the time and I was able to sluggishly drive the car safely into an adjacent parking lot. I, as well as other could have been seriously injured or killed. All wheels and tires are visibly damaged and possibly the underside as well. The car is in a body repair shop and waiting for inspection at this time. I already reported the incident to my insurance and Tesla companies. All inspections and reports are pending at this time. There was no police report since there was no collision or bodily injuries. There were no warning signs, signals, messages, or symptoms from the car or from Tesla before the incident. The car 12V battery was changed 3 months prior by Tesla Service Center. This is my first encounter with this sort of problem.
