What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The check engine warning light was illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the transmission. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The vehicle was then taken to an independent mechanic, who confirmed the diagnosis.
Tl* the contact owns a 2015 infiniti qx50. The contact stated that while driving at various speeds, the auto dimming feature was fractured causing it to be very difficult to see at night. The failure occurred multiple times.
Without power steering and brakes I was still able to guide it to the curb and come to a safe stop. What I attempted to restart the car it acted as if the battery didn't have enough power to turn over the engine, although lights, horn and radio still worked fine.
