Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Over the last couple of days, my car has displayed the Engine Warning message intermittently. I took this to the dealership for inspection and received the following fault code: P06DA00 - Inoperative Oil Pump Valve. For a car with low mileage, this could potentially be a car issue. The estimated total cost for labor and parts is over $5k. I think there are more cars affected.”

“The contact owns a 2020 Mercedes-Benz E350. The contact stated that while driving at an undisclosed speed, the contact detected an abnormally strong fuel odor inside the vehicle. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic and the dealer, who determined that the fuel injector in cylinder #3 needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 21V961000 (Fuel System, Gasoline); however, the VIN was not included in the recall. …”
