Owner report 10164920 · 2006-08-08 (August 8, 2006)
HFM & OTHER WIRING HARNESSES ARE DETERIORATED. VEHICLE HAS BEEN MAINTAINED TO MANUFACTURERS RECOMMENDATIONS SINCE NEW. DETERIORATED WIRING HARNESS CAUSES CHECK ENGINE LIGHTS, IGNITION MALFUNCTIONS, ELECTRICAL SHORTS OCCUR IN THE ENGINE COMPARTMENT. WIRE INSULATION / COATINGS ARE OBVIOUSLY NOT UP TO THE TASK. THIS IS DANGEROUS SITUATION. *JB

Owner report 10924326 · 2016-11-04 (November 4, 2016)
FACTORY MATERIAL DEFECT. ENGINE WIRE HARNESS INSULATION IS BREAKING DOWN AND FLAKING OFF, LEAVING EXPOSED WIRE. IGNITION IS POOR AND THREATENS TO STALL, ESPECIALLY WHEN ENGINE TEMPERATURE WARMS UP TO 85-90C. I FEAR THE ENGINE MAY FAIL OR CATCH FIRE DURING A DRIVE AND CAUSE AN ACCIDENT. THERE IS ALSO A SHORT IN THE AUDIO SYSTEM. THE VEHICLE IS BEAUTIFUL. IT IS A SHAME TO HAVE IT SITTING SINCE 2008. *TR
