What owners report

  • Engine coolant loss leads to smoking and towing, with one owner's repair occurring at 26,287 miles matching the pattern seen in the median engine-failure mileage.
  • Engine shuts off suddenly while driving, including during turns, triggering a stop/start warning and locking the steering wheel.
  • Vehicle stumbles or loses power briefly while idling or driving, then regains power moments later.
  • Brake pedal pulsates and stopping distance increases due to warped front brake rotors, diagnosed by a dealer.
  • Airbag recall parts remain unavailable for extended periods, leaving owners without a repair timeline despite an active Takata-related airbag light.
  • A body seam not welded properly allows water to leak onto electrical modules, triggering warnings that adaptive cruise and braking are unavailable.
