On [XXX], I was exiting the freeway and went over a slight bump in the exit lane. I went to engage the brakes, and my car lunged forward (24V865000). Shortly after turning left from the freeway exit, my car began to stall and shut down — displaying an issue with the main battery. My car kept stalling and shutting off and had to be towed (24V404000). I had a mobile tech come out to try and repair the car. He replaced the 12v battery and ensured the PDU / front of the car was functional and working properly. He determined that there may be an issue with the High Voltage Battery and recommended it be taken to a repair shop. He also confirmed that even though my car said it was on 2.2 Software, it was not even partially installed. I called the approved service center in Newport, CA and they informed me they would not be able to work on my car. So, I had to tow my car to Riverside, CA as it’s the only other repair shop in Southern California. This incident occurred after I replaced my water pump (24V499000) in Riverside and had to pay $150 out of pocket. My car has been in the shop for at least 2 weeks and I was told it may not be repairable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
