Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I came back from my summer holiday, and restarted my car. A lot of warnings appears on the odometer. About engine, airbags, steering, tire pressure, and seat belt. (I have checked the tire pressure, it is normal. And I always lock the seat belt before driving). In addition, the navigation screen and radio died. Furthermore, the car lose electricity after it shuts down. After more than 3 hours of shut down, it won't have enough power to re-ignite. I check on NHTSA website that there are three recall issues that my car was included, and related to the issues I am reporting right now. …”
NHTSA complaint #11015508, filed 2017-08, 106,590 miles“On Bmw with the n62 4.4l v8 engine there's an oil leak on the alternator bracket that leaks for a while until it is inspected and found it leaks oil on the steering components I think causing the steering components to deteriorate after a while causing a safety issue. The oil leak eventually happens to all n62 4.4l v8 engines.”
