NHTSA COMPLAINT (VERY IMPORTANT – SAFETY FOCUSED) Subject: Safety Complaint – BMW X7 Electrical Defect and Fire Risk (VIN: [XXX] ) To the National Highway Traffic Safety Administration, I am submitting a formal safety complaint regarding a 2020 BMW X7 xDrive40i affected by Recall No. 24V-576 (Engine Starter Defect).
The vehicle suffered a complete premature failure of the factory aluminum A/C evaporator core due to internal corrosion. This is a known, widespread issue on BMW G-chassis vehicles.
2020 bmw x7 with 34k miles 1 driver, front suspension control arm leaking causing clunk and un even steering / braking feel due to premature leaking of the hydraulic fluid do to a design flaw.
Additionally, there have been multiple issues with the rear sunroof not working properly and noises happening when the front sunroof is opened. BMW is recommending replacing the driver door actuator and attempting to program the body domain controller with a possible BDC replacement if programming is unsuccessful.
Low oil sensor continues to light up and says i am low on oil. Found out that my oil pump was the main cause of the issue. At this time I have to have the oil pump replaced. It was also determined there have been numerous reports regarding oil pump failure in the 2020 BMW x7 due to an internal plastic part.
The front thrust arm bushing was previously replaced on December 19, 2023, at 34,750 miles (after three years of ownership). It has now failed again at 57,203 miles, lasting only about 22,500 miles.
My vehicle experienced a sudden loss of engine oil pressure that resulted in catastrophic engine failure. This condition occurred with little to no warning and led to immediate vehicle disablement.
It has repeatedly failed to start, and on two separate occasions the engine completely stalled while I was stopped at a traffic light. Each time, it took multiple attempts before the car would restart.
