NHTSA Complaint #11702773 — 2013 BMW X3

While driving my 2013 BMW X3 xDrive28i under normal conditions, a “drivetrain malfunction” warning suddenly appeared, immediately followed by a “low oil pressure” warning. Within seconds, the engine lost all power and shut off completely while the vehicle was in motion. I had to coast and steer the car off the roadway and push it to safety with the help of others. My safety and the safety of other drivers were at risk due to the sudden and complete loss of propulsion in active traffic. An independent BMW-trained service center confirmed that the engine suffered catastrophic internal damage caused by failure of the timing chain system. This timing chain defect is well documented in BMW’s N20 engines and is the subject of a class action lawsuit. The vehicle is now completely undriveable and remains at the repair facility. Engine replacement is the only option and is estimated between $12,000–$15,000, far exceeding the value of the vehicle. The failed engine and vehicle are available for inspection upon request. The problem has been reproduced and confirmed by an independent BMW specialist. BMW has not yet inspected the vehicle, although I did call and report to BMW North America. They have not responded to my numerous calls and outreach. No police or insurance representatives have inspected it because there was no collision, just sudden engine failure. There were no symptoms before the incident. The drivetrain and oil pressure warnings appeared only moments before the engine shut down. I had no opportunity to safely exit traffic before the vehicle lost power completely. This sudden failure due to a known engine defect presents a significant safety concern.
