3 Series years to avoid—and the years we refuse to over-rank

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

“The contact owns a 2019 BMW 330i. The contact stated that while driving at 60 MPH on a three-lane highway, traveling in the exit lane, and using the hands-free calling system to speak with his wife, the vehicle crashed into an unknown metal object in the roadway, which tore the undercarriage. The driver-side air bag exploded without warning, resulting in him sustaining a concussion, and the vehicle came to a stop. The emergency call system failed to activate. His wife was able to contact 911, who was delayed in locating the incident site. The fire department, ambulance, and police department were on the scene. The contact was treated at the scene by the ambulance. The contact went to a walk-in clinic the next day, where medical attention was provided. There was no reported fire or police report filed due to the lack of identification of any damage. The vehicle was towed to the local dealer, who determined there was damage to the undercarriage. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The contact had written a letter to send to the manufacturer. The failure mileage was approximately 51,443.”

“Car was t-boned by another vehicle at 65-70 MPH (other driver was cited as negligent and responsible for accident)—and other driver’s car caused damage to the BMW and driver (my daughter) due to the side airbags on the BMW not deploying (damage to daughter would have been significantly less had the BMW side airbags deployed as they should have upon impact).”

“Going into a parking spot. Applied brakes, then the car did not brake, then it accelerated hitting a Jeep and finally stopped when the driver side front hit a parking barrier and then the air bags deployed. Sudden unintended acceleration was the cause of this accident. Car was totaled.”

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.”
