What owners report

  • Timing chain stretches and produces a rattling noise on engine startup, sometimes recurring within about 13 months of a prior repair.
  • Engine vibrates and the check engine light comes on shortly after starting.
  • Flywheel and clutch burned out at low mileage, with owners saying dealers resisted covering the repair.
  • Oil mixes with coolant, leading to engine head failure, loss of power while driving, and stalling.
  • Passenger airbag warning light stays on intermittently or continuously, which owners link to a seat sensor issue similar to a recall on earlier model years.
  • Electrical faults cause bulbs to fail, water intrusion, and poor overall performance.
