Open the full vehicle complaint log (all categories)Catastrophic failure of Bosch CP4 high-pressure fuel pump in my 2014 Porsche Diesel Cayenne. Resulted in metal shavings/shrapnel throughout entire fuel system. Car abruptly stalled while pulling out of parking lot and was unable to restart. Had vehicle towed to nearest Porsche dealer for repairs. Quote for parts only (without labor) to repair vehicle is $29,440.47. With labor is in excess of $40,000. Car has been determined to be a total loss. My 2014 Porsche Diesel Cayenne has always been maintained at suggested intervals and all service work for the life of the car was performed by Porsche. It has been a wonderful, reliable and fun vehicle to drive prior to this horrible event. No warnings of fuel pump failure came up on vehicle warning and message system.
TRANSFER CASE FAILURE AT 91,000 MI. ERRATIC ACCELERATION AND CLUNKING AND JERKING OF VEHICLE WHILE IN MOTION.
FUEL GUAGE ERROR EVEN WHEN TANK IS MORE THAN HALF FULL, FUEL GAUGE ERROR POPS UP INTERMITTENTLY WHILE DRIVING.
THE CAR WOULD NOT START AFTER MULTIPLE ATTEMPTS. THE SUV NEEDED TO BE TOWED TO THE NEAREST DEALERSHIP. THEY SAID THE FUEL GELLED AND RECOMMENDED THAT "I" HAVE THE FUEL STATION PLACE THE 'CORRECT ADDITIVE' TO THE DIESEL FUEL. MY HUSBAND HAS HAD TWO DIESEL VEHICLES FROM OTHER CAR MANUFACTURERS FOR THE PAST 4 YEARS, BUT HE HAS NEVER HAD ANY ENGINE START PROBLEMS. HE IS STILL FILLING HIS TANK AT THE SAME STATION. SINCE THEN, I HAVE CHANGED THE DIESEL FUEL STATION AND NOW GO TO ANOTHER BUSY PLACE. THE SAME THING HAPPENED TODAY, TWO (2) WEEKS LATER, WITH A DIFFERENT DIESEL FUEL SOURCE. VEHICLE WOULD NOT START (ODOMETER READS 4980 MILES) THE DEALERSHIP (FROM WHERE THE SUV WAS PURCHASED) COULD ONLY MAKE THE RECOMMENDATION TO MOVE THE VEHICLE, WHICH WON'T START, TO AN INDOOR GARAGE. IN OUR AREA, THIS IS IMPRACTICAL. VERY FEW COMPANIES AND STORES PROVIDE INDOOR GARAGES. I HAVE BEEN ON THE PHONE MULTIPLE TIMES. THE PORSCHE DEALERSHIP HAS NOT BEEN ABLE TO COME UP WITH ANY OTHER RECOMMENDATIONS UNTIL NOW, 7-1/2 HRS SINCE MY FIRST CALL. *TR
