Electrical system
4 reports1 fire
“THE PCM UNIT WHICH CONTROLS THE CARS COMPUTERS KEEPS SHUTTING ON AND OFF SAYING DO NOT DRIVE. GET SERVICE ….. THIS HAS HAPPENED ON MANY CARS AND THERE WAS A CLASS ACTION SUIT REGARDING A RECALL. IT IS NOW CLOSED AND I WAS NEVER NOTIFIED.”

3 reports1 fire

A FORENSIC INVESTIGATION REVEALED THAT THE CAUSE OF THE FIRE WAS THE ELECTRICAL BOARD LOCATED ON THE INSIDE OF THE CABIN NEAR THE RIGHT REAR TIRE.

I PARKED THE VEHICLE AND FOUND THAT THERE WAS A SMALL FIRE IN THE ENGINE COMPARTMENT. I COULDN'T GET TO THE CAR IN TIME WITH A FIRE EXTINGUISHER AND BY THE TIME THE FIRE DEPARTMENT ARRIVED, THE CAR WAS ENGULFED IN FLAMES. I'M NOW FACED WITH A TOTAL LOSS FOR THE VEHICLE AND NOT TO MENTION RELUCTANCE TO EVER PURCHASE ANOTHER PORSCHE IN MY LIFE.

IF MY FAMILY HAD BEEN IN THE CAR WITH ME, THIS COULD HAVE TURNED OUT DISASTROUS AND FOR THAT MY CONFIDENCE HAS BEEN SHATTERED WITH PORSCHE. I AM ALSO LEFT SEARCHING FOR A CAR THAT IS CLOSE TO AS NICE AS THE CAR I HAD (FULLY SPEC'D AND DECKED OUT CARRERA…”
