What owners report

  • Airbag warning lights illuminate intermittently around 30 mph, sometimes with a passenger in the seat, without dealers able to duplicate the fault.
  • Passenger seat occupancy sensors for the airbag system fail, raising concern the airbag would not deploy in a crash.
  • Driver and passenger seat heaters have caught fire or smoked, including one case causing a burn injury.
  • Sunroof drain lines clog and route water into the trunk area, in one case leading to a fire near the battery and spare tire compartment.
  • Electric seat adjustment stops functioning while the vehicle is idling.
  • Transmission shifts abnormally while braking at 20-40 mph, which owners linked to a programming error.
