What owners report

  • Owners report the power transfer unit (PTU) leaking fluid that ignited near the exhaust, damaging the transmission housing and causing powertrain failure.
  • Airbags reportedly failed to deploy in multiple crashes, including rear-end and head-on collisions, sometimes with the air bag warning light on beforehand.
  • Some drivers describe sudden unintended acceleration while trying to park, with the vehicle not stopping despite braking.
  • Power steering reportedly failed abruptly during a turn, making the wheel impossible to center even with heavy force.
  • Owners report turbo failure that let oil burn through the engine, producing heavy exhaust smoke, in one case at 110,000 miles.
  • Some report suspension or wheel issues, including a broken toe link and rear tires coming off the rims at highway speed.
