NHTSA Complaint #11713799 — 2019 BMW X3

On returning to my locked vehicle that had been in the parking ramp for 3 days, I started the car and the display message indicated that my vehicle was completely out of gas and the oil was very low. The vehicle had nearly a full tank of gas when it was parked. The vehicle was towed to the dealership who assessed the vehicle. The service department indicated that the vehicle likely did not sound like it was running because of the idle feature, and as such, I may have thought I shut off the car, but that eventually the idle feature turned off, and the vehicle ran while it was locked until it was out of gas. The service man who sent me a video of my vehicle and described what happened, also showed me another BMW SUV in the hoist next to my vehicle and indicated that same vehicle had the same thing happen as well. BMW replaced the programing/encoding control units software that was original to the vehicle. They indicated that this would improve overall function of the vehicle. The cost of this replacement was $371. This sounds like a design flaw. How can a locked vehicle start back up after a period of time, by itself with no vehicle fob in the vicinity, and run for hours until it is out of gas and the oil is low?
