Example complaints

Fuel system: “The fuel gauge is not working, the car is reading as full the whole time. As my wife and I share the car, we always assume the other was re-filling it, until it died on her. Worst is that, they will not keep it for repair as they don't have the parts. They send you with this safety risk away telling you to re-fuel it every 200 miles.”

NHTSA complaint #11151691, filed 2018-11, 280 miles

Brakes: “The contact owns a 2018 Acura ILX. The contact received notification of NHTSA Campaign Number: 25V859000 (Service Brakes, Hydraulic) however, the part to do the recall repair was not yet available. The local dealer was contacted and confirmed that the remedy was not yet available. The contact stated while driving at 30 MPH, while the brake pedal was depressed the brakes failed to engage; the contact had to crash into the medium in between both sides of the street to avoid a crash. No warning lights were illuminated. …”
