NHTSA Complaint #11419567 — 2013 BMW X5

As I was exiting a public Starbucks parking lot near my home with my foot on the brake slowly releasing it (as I had a car in front and behind me) my 2013 BWM X5 accelerated on it's own. I quickly glanced at the pedals thinking I might have stepped on the accelerator instead of the brake, but no. My foot was on the brake. I stomped on the brake as hard as I could while the vehicle was jerking and stalling. The car in front of me exited the parking lot and luckily I didn't crash into it. This kept going for about a minute it was as if I had been stepping on the accelerator and brake at the same time. I tried turning off the vehicle, but nothing happened. Finally, after about a minute (or maybe a little more) the engine turned off and the car stopped moving. There was an ATM the right of me with a few people making line. They offered to help me push the vehicle out of the way as I was blocking a very tight parking lot exit, but I was unable to put the car on neutral, drive or anything. I was in shock and very scared of what had just happened. I had my car towed to the nearest auto repair shop where I explained the situation the the auto repair people. I was advised to call BWM as the repair shop was unwilling to give me a diagnosis due to the nature of the incident. I called BMW of North America, reported the incident and after about 2 weeks BWM had my vehicle towed to BMW of San Diego where an investigation was going to be done. After 3-4 weeks I received the results. Since the engine did not start they could not find the cause of what made the vehicle accelerate on it's own in such a way. They did have other irrelevant findings like an after market oil filter and debris in the oil. The final report was that the engine had to be replaced. I asked for an estimate from BMW and they came back with $20,993.50 (which is more than what I paid for the car). Even if I was to replace the engine, I don't trust the car anymore. BMW of San Diego is holding my car as a courtesy.
