What owners report

  • Driver's seat catches fire while driving, with owners tracing it to a malfunctioning seat warmer that ignites the seat backing or lumbar area.
  • Burning odor or visible smoke appears inside the cabin, sometimes burning through the leather seat and clothing before self-extinguishing once the seat warmer is turned off.
  • Brake pedal reportedly goes to the floor with no warning lights, forcing use of the emergency brake to stop.
  • Vehicle rolls away after being put in park with the emergency brake engaged, using the touch-shift control instead of a traditional shift lever.
  • Loud rattling noises come from the steering column and other areas, accompanied by sunroof malfunction that a dealer initially could not fix.
  • Headlight lens turns foggy inside, cutting off proper beam output at night, which the dealer described only as normal discoloration.
