What owners report

  • Owners report the vehicle lurching or jerking hard into drive or reverse after startup, sometimes hitting objects before it could be stopped.
  • Transmission makes noise when downshifting around 15 mph or during startup, with slipping that worsened even after dealer reprogramming and a new computer part.
  • Some drivers describe the transmission lunging forward on its own when releasing the brake pedal, with the problem worsening over a couple of months.
  • Thermostat housing units reportedly leak, a problem some owners say is common on this vehicle and potentially dangerous.
  • A windshield cracked without any impact while the vehicle sat parked, starting from the bottom edge.
  • Front bearings connecting to the all-wheel-drive system failed at low mileage in at least one reported case.
