Engine

3 reports1 fire
“IN MAY 2019 I PURCHASED A CERTIFIED PRE-OWNED 2015 PORSCHE CARRERA GTS AND HAD IT FOR 11 MONTHS BEFORE IT CAUGHT ON FIRE WHILE DRIVING IT. 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. ON THE DAY OF THE INCIDENT, AFTER DRIVING THE CAR LESS THAN 15 MILES FROM MY HOME TO A NEARBY PROPERTY I NOTICED THE CAR WAS SMOKING AS I PULLED INTO THE DRIVEWAY. 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. I'VE DREAMT ABOUT OWNING THIS PORSCHE CARRERA (GTS) SINCE I WAS A CHILD AND THIS EXPERIENCE HAS TOTALLY ALTERED MY PERCEPTION. 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…”
