Typical electrical symptoms owners report

  • Xenon (HID) headlights flicker, then shut off, often showing a "left dipped headlight" or "right dipped headlight" warning on the dash.
  • Turning the affected headlight switch off and back on temporarily restores it, but the flickering and shutoff recur, sometimes daily.
  • Failures were reported at a wide range of mileages, from as low as 18,000 miles up to 92,000 miles.
  • One owner reported the #1 ignition coil pack failed under normal driving, followed a week later by a second coil pack failure while driving on a highway.
  • One complaint described smoke entering the passenger compartment and a small fire at the ignition coil on top of the engine, which was extinguished and repaired.
  • Dealers in several cases could not identify a root cause, sometimes suggesting bulb or ballast replacement without resolving the flickering.
