What owners report

  • Keyless ignition allows the car to be shifted out of park before the engine is started or the key fob to be turned off without the vehicle being in park.
  • Owners report the radio, power steering, and door locks shutting off intermittently while driving, sometimes requiring the car to be restarted.
  • Front driver and passenger airbags deployed without a crash while the vehicle was moving at highway speed, causing loss of steering control.
  • A temperature sensor issue can trigger a fault code that puts the transmission into limp mode instantly during heavy traffic, along with coolant leaks and overheating.
  • The evaporative emissions (EVAP) purge system was reported to leak, and the engine shut off unexpectedly while driving.
  • The plastic thermostat housing cracked and caused a sudden, rapid loss of engine coolant.
