While parking the car it accelerated up over the curb and into the bushes in an office parking lot. The sudden unintended acceleration occurred in B mode with the automatic cruise control system setting to follow the posted speed limit when activated. The cruise control was not activated by the driver at the time of incident. The car went from 0mph to full acceleration while the parking distance system was activated. I am reporting this issue to make others aware of the accident, in case a similar issue happens with other cars. The car is new and only has about 250 miles on it at the time of accident. The insurance company has received the initial claims info and is fixing the car. No warning, messages or indicator preceded the accident.

On March 23, after driving approx 2 miles, I was at a red light. The light turned green and I began accelerating. There was a loud "bang" from under the car toward the rear, the car abruptly halted, the displays turned red with a message (all caps) DO NOT DRIVE. I power cycled the car a few times and the error cleared, but my state-of-charge had dropped from 77 to 59%. I drove the car the 1 mile home and called BMW Roadside Assistance. The rep asked for permission to pull logs from the car, told me he would be sending a flatbed Monday morning and advised me, in no uncertain terms, DO NOT DRIVE THE CAR. I asked if I could pull the car out of the driveway and he said no; he would send skids with the driver. Friday afternoon I was advised there was nothing wrong and to pick up the car. The work order is blaming an LA DWP 50KWh charger I had used 2 days prior to charge from 65 to 81% and recommends avoiding this charger. Just to be clear, I charged 15% on 3/21 and the car went "bang" on 3/23, and that was the fault of the charger.

On November 18, 2025, I was driving a 2025 BMW i4 eDrive, VIN [VIN], at approximately 10–15 mph in slow traffic. I applied the brake pedal firmly when the vehicle in front of me slowed, but the vehicle did not decelerate as expected. The vehicle continued moving forward, resulting in a rear-end collision with the car in front of me, which in turn struck another vehicle. Prior to this incident, the vehicle occasionally exhibited brief reductions in forward drive power that were subtle and initially attributed to drive mode (e.g., comfort/eco or battery status). At the time of the incident, the vehicle was subject to Safety Recall 25V-395, but I had not received any recall notification prior to reporting the incident to BMW. This appears to be a potential vehicle safety defect involving braking performance or interaction of propulsion and braking systems, as the vehicle did not stop when brake input was applied under normal conditions. I am reporting this to NHTSA for investigation of a possible safety defect. Related documents, including accident reports, repair invoices, and correspondence with BMW regarding ongoing investigation and requested diagnostics, are available upon request.
