What owners report

  • Airbags fail to deploy in real-world crashes despite the vehicle being under a Takata recall, in some cases with owners reporting head injuries.
  • Front air struts/shocks lose pressure and the car lowers with a dashboard warning light, sometimes reported after a prior crash.
  • Rear or front air suspension leaks out over a period of hours, causing the car to sit lopsided or unable to be driven level.
  • Owners with Takata recall notices report that replacement airbag parts were unavailable for an extended period after notification.
  • Front brake rotors and discs reportedly overheated and warped, with the dealer confirming warped rotors during inspection.
  • A water leak developed above the rearview mirror after cosmetic collision repairs, reported as persistent.
