What owners report

  • Water pump can fail and leak coolant, triggering a 'stop engine' warning and steam from the engine bay while driving.
  • Engine may surge or stumble on cold starts, with RPM cycling between roughly 500 and 1,800 for several seconds and occasional stalling.
  • Steering wheel can develop severe wobbling or pulling to one side, sometimes requiring repeated wheel alignments.
  • Diesel-equipped versions can lose all power suddenly from high-pressure fuel pump failure, damaging the fuel line system.
  • Vehicle can lurch or pull hard when shifted into drive or reverse after sitting for several hours, requiring firm braking to control.
  • Door latch or keyless entry sensors can fail, preventing the door from locking or the alarm from arming.
