What 44 owners told NHTSA about the 2023 BMW I4 Gran Coupe Bev

While driving my 2023 BMW i4, the vehicle suddenly displayed multiple drivetrain and chassis malfunction warnings shortly after charging the vehicle at a ChargePoint station. The vehicle experienced a sudden loss of power/propulsion while driving, creating a serious safety concern. After stopping, the vehicle began rolling backward unexpectedly and several systems appeared to malfunction. The center display/screens became partially or fully unresponsive/blank and multiple warning messages appeared simultaneously. Due to the loss of propulsion and safety concerns, CHP assistance was required to safely move the vehicle off the roadway. The vehicle was later towed to BMW service for inspection and diagnosis. I am concerned this may involve a failure related to the electrical system, high-voltage battery system, propulsion system, drivetrain, or vehicle software. The sudden loss of power while operating the vehicle created a dangerous driving condition. The vehicle had approximately 76,000 miles at the time of the incident.

While merging onto an interstate at speed, the vehicle experienced a sudden loss of motive power and came to a complete stop in an active traffic lane. Approximately six weeks earlier, abnormal drivetrain behavior (hesitation and torque interruption) was reported to the dealer. The dealer attributed the issue to tires and recommended tire replacement. No drivetrain diagnostics were performed. Immediately following the incident, a drivetrain malfunction warning occurred. BMW remotely restricted vehicle operation to allow limited driving back to my residence. The vehicle was later towed to the dealer. BMW subsequently confirmed catastrophic electric motor failure requiring full motor replacement. The incident created an immediate risk of collision with surrounding traffic and represents a serious safety defect involving unexpected deceleration and loss of propulsion.

I am reporting a recurring safety issue with my 2023 BMW i4 (VIN: [XXX] ), currently at 28,426 miles. The vehicle has experienced three separate incidents of unexpected and complete loss of power while driving. The first incident occurred in March 2025. The vehicle suddenly lost all propulsion without warning and came to an immediate hard stop. I was later informed this was related to a wheel-positioning sensor. The second incident occurred in October 2025. I had been told that a recall software update would resolve the problem, but the vehicle experienced another loss of power while in motion, showing the issue was not corrected. The third and most concerning incident occurred in November 2025. Multiple error messages appeared instructing me to stop driving immediately, and the vehicle again lost power while moving. A complete loss of propulsion in traffic—especially while merging or pulling into a roadway—creates a severe safety hazard because I am unable to move the vehicle out of the way of oncoming traffic. This puts both myself and other drivers at risk. BMW has acknowledged awareness of issues related to these systems during previous service visits, but the defect continues to occur despite attempted repairs and software updates. I am requesting that NHTSA investigate this matter, as repeated power-loss events pose a significant safety risk that could lead to crashes, injuries, or fatalities.

Vehicle is an EV (platform G26) and charger flap door was locked and would not open. Problem is similar to problem reported on NHTSA for BMW vehicles for "fuel filler door will not open", SIB 51 27 20. Safety issue is vehicle can not be charged and creates risk for driver and passengers being stranded. Older BMW vehicles had an emergency release but new models eliminated this feature. Vehicle was taken to dealership for repair and item know as cover pot defect was confirmed and replaced. Requested confirmation that replacement part addressed root cause but dealership would not offer any assurances.

A small spill of liquid (unsweetened iced tea) on the gear shift area inches from the cup holder shorted out the entire transmission of the vehicle, rendering it immovable. This happened while pulling into our garage, but if it had happened while the car was moving on the road it could have caused a catastrophic accident.
