Typical engine symptoms owners report

  • Sudden loss of acceleration or unresponsive throttle while driving at highway or merging speeds, sometimes with the pedal feeling stuck or sunk into the floor.
  • Glow plug warning light triggers a loss of power and "limp mode," with the issue recurring even after dealer repair attempts.
  • Engine burns excessive oil, requiring frequent top-offs and showing black exhaust residue, reported by owners with higher-mileage vehicles.
  • Check engine light triggered by faulty electronic control monitor (ECM) or secondary air port fouling, with dealers describing some conditions as not warranty-covered.
  • Intake pipe between the intercooler and turbo can dislodge when joining bolts back out, cutting off throttle response mid-drive.
