When: [XXX] approximately [XXX] AM Where: [XXX] coming down from office complex [XXX] While driving approximately 25-30 mph down a winding road with a moderate hill, my 2024 BMW I4 suddenly accelerated as if the accelerator pedal was suddenly floored, causing me to struggle to keep the car in control, and only several seconds after slamming on the brakes was I able to stop the car. No warning lights ever came on in the dash at any time. It was only luck that someone wasn't injur]ed or killed. Fortunately there were no other cars near, and I didn't run off the road or crash the car. I immediately drove slowly to Bob Smith BMW in Calabasas. They have the car and BMW North America is looking into it. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
While driving on the right lane of [XXX] I received a notification on the screen stating "DRIVE TRAIN: FAULT PULL OVER FOR SAFETY" and just as I attempted to turn the steering wheel to enter the shoulder lane of the highway, the car stopped. I was stuck in the right lane of the highway with cars and huge semi trucks swerving around me at 60+ MPH while I was on the phone trying to get help from roadside assistance BMW and 911. I was unable to start the car or put it in neutral to even try to move it off the road. I climbed out of the passenger side of the car to get far away from the car until the state police arrived. Officer K. Kelly of Elizabeth NJ state police arrived after a few minutes and blocked traffic behind me with his police lights and called a tow truck for me because I was also unable to locate where I was to call one to my location. I had to have the car towed off the highway, then call a town truck again to have it towed to the dealer. I can understand if this was an issue and I was stuck at home in my driveway, but in the middle of the highway and not allowing me a chance to turn off into the shoulder for safety is UNACCEPTABLE. I am contacting BMW North America as well and going to further escalate this matter. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
