NHTSA complaint #11449735

Owner complaint summary

The contact owns a 2021 BMW X5. The contact stated that as her husband was stopped at a stop light, the vehicle began to rev after he had taken his foot off the brake pedal without warning. Once her husband placed his foot back on the brake pedal, the revving stopped, and her husband was able to resume normal driving. On a separate occasion, her husband was waiting for a vehicle to move out of a parking spot; the same failure occurred as her husband took his foot off the brake pedal. Her husband was forced to slam on the brakes as the engine continued to rev and the vehicle lurched forward. The contact who was seated in the passenger’s seat, shut off the vehicle to avoid hitting the vehicle in front. Her husband restarted the vehicle and drove it home; he then had the vehicle towed to the dealer the next day. The dealer inspected the vehicle but could not duplicate the failure. The service tech was not satisfied with the results and decided to call the manufacturer to approve more testing of the vehicle. The vehicle had yet to be repaired and remained in the possession of the dealer. The failure mileage was approximately 14,000. The VIN was not available.
