What owners report

  • Brake pedal produces a popping sound or sensation on every application, raising concern about a loose component.
  • Power liftgate closes on its own without a hands-free gesture or key fob activation, striking a person nearby.
  • Throttle pedal assembly detaches from its floor mounting studs because retaining nuts are missing, leaving it unstable.
