2019 BMW 3 Series Speed Control & Cruise Problems

My 2019 BMW 330i experienced a serious malfunction. The car intermittently blacked out upon pressing the start engine button, and then it began accelerating on its own without pressing the accelerator pedal. This occurred multiple times, and the issue has not been resolved or explained by the service center, which has resulted in a significant safety concern. What component or system failed or malfunctioned, and is it available for inspection upon request? It appears that the issue might be related to the car's ignition and acceleration system. How was your safety or the safety of others put at risk? The car began accelerating on its own without pressing the accelerator pedal. This could be extremely dangerous if it happened while driving, as it could lead to loss of control and a potential accident. Fortunately, I was parked when this occurred. Has the problem been reproduced or confirmed by a dealer or independent service center? BMW Mountain View, CA service center were not able to reproduce it. They just changed the 12V battery but were not able to provide concrete reason or reproduce the issue. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has been inspected by the service center but not by the manufacturer, police, insurance representatives, or others. Despite multiple requests from both myself and the dealership for further examination, BMW North America is not willing to involve their engineering team. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps or messages prior to the issue. This situation could have been very serious if the unintended acceleration happened while driving. I was fortunately parked at the time and did not try to put the car in gear to avoid any potential accidents.
