Owner-reported Unknown Or Other symptom: affected BMW 3 Series years

One owner report describes this symptom. Frequency, causation, and population risk are unknown.

“Hours after a software update to the vehicle, a sudden unintended acceleration event occurred as I pulled into the alley of my office's driveway/garage. The brakes failed to work, and the vehicle rapidly accelerated in less than 2 seconds. In order to avoid endangering anyone, I steered the vehicle into City trash cans that were in front of a telephone pole. The vehicle was completely damaged, and both my passenger and I sustained severe injuries, including a vertebral compression fracture and torn neck ligaments. The vehicle is currently undergoing inspection by my insurance company. My safety was jeopardized entirely. If the vehicle had not collided with the telephone pole, it would have entered a street full of cars, thereby endangering pedestrians and other drivers. As of now, the issue has not been reproduced or confirmed by the dealer, and no attorney is willing to pursue the case due to the exorbitant costs associated with litigating against a major auto manufacturer. The police were present at the crash site, and the insurance company is currently examining the vehicle. There were no warnings displayed on the dashboard, nor was there any unusual behavior exhibited by the vehicle prior to the incident.”
