The contact stated that while driving approximately 45 MPH, there was an abnormal sound coming from the front passenger’s side of the vehicle, and the front passenger’s side tire started deflating.

The cause of the failure was not yet determined. The contact stated that the vehicle had not driven over any object to cause the failure. The tire manufacturer was not contacted. The vehicle manufacturer was not notified of the failure. The failure mileage was unknown.

Our 2018 Porsche Cayenne has a problem with the headlights and water intrusion that is affecting the functioning of the headlights. I took it to someone to look at and they said this should not be happening, that it is a manufacturer defect. I googled my car / year and there is a recall for headlight issues but for some reason my VIN is not included. It should be. How do I go about having Porsche North America fix this issue for me?

2018 PORSCHE CAYENNE: AT HIGHWAY SPEEDS, RANDOMLY A SERIOUS UNSAFE TO OPERATE 'SERVICE NECESSARY' WARNING APPEARS ON THE INSTRUMENT PANEL AND THE CRUISE CONTROL MALFUNCTIONS. WITH THE SERVICE NECESSARY WARNING INDICATED, THE VEHICLE IS UNSAFE TO OPERATE. THIS UNSAFE VEHICLE IS NOT DRIVABLE WITH CRUISE CONTROL FOR APPROXIMATELY THE NEXT HOUR. THIS BREAKDOWN IS KNOWN TO PORSCHE (VIA THEIR COMMUNICATIONS WITH ME) AND THEY ARE UNABLE TO RECTIFY THE ERROR. IN A 2020 PORSCHE CAYENNE THIS FAILURE HAS BEEN RECTIFIED. ATTACHED, INVOICES FROM FIVE VISITS TO PORSCHE DEALERSHIPS, ALL DURING THE WARRANTY PERIOD. ATTACHED ALSO PHOTOGRAPHS TAKEN ON VARIOUS DAYS, TIMES AND SPEEDS, AND TRAFFIC CONDITIONS OF THE SERVICE NECESSARY WARNING ON INSTRUMENT PANEL AND CRUISE CONTROL MALFUNCTIONS.

WHEN TRYING TO ACCELERATE INTO TRAFFIC VEHICLE WILL EXPERIENCE WHAT FEELS LIKE A DEAD SPOT IN THE ACCELERATOR AND THEN LURCH FORWARD AT A HIGH SPEED THIS CONDITION HAS BEEN REPORTED ON NUMEROUS COMPLAINT SITE CONCERNING VARIOUS PORSCHE VEHICLES AND SPECIFICALL CONCERNING PORSCHE CAYENNE DEALER SAYS CAR IS FINE.UNSAFE TO DRIVE SINCE YOU NEVER KNOW WHEN IT WILL ACCELERATE.

THE CAR LOST POWER AND STALLED ON THE HIGHWAY WITHOUT WARNING, THE ROAD WAS THE GARDEN STAT PARKWAY IN NEW JERSEY , HAPPENED IN MID NIGHT

INTERMITTENT LACK OF ACCELERATION WHEN TAKING LEFT TURNS FROM A DEAD STOP. CAR WAS A DEALER LOANER WITH 9000 MILES ON SPEEDOMETER. I PURCHASED THE CAR IN AUGUST, 2018. WITHIN THE FIRST 1000 MILES AND IN LESS THAN FOUR WEEKS I EXPERIENCED A SERIOUS LACK OF ACCELERATION ON TWO OCCASIONS WHEN MAKING A LEFT TURN, I REPORTED THIS TO THE DEALER AND WAS ADVISED THAT IT WAS PROBABLY DRIVER ERROR CAUSED BY OPERATING THE BRAKE AND ACCELERATOR USING BOTH FEET. I DO NOT DRIVE AN AUTOMATIC CAR USING TWO FEET. ALSO, I WAS TOLD BY THE DEALER THEY CHECKED WITH PORSCHE AND THERE ARE RECORDS OF THIS TYPE OF EVENT. I CHECKED ON THE INTERNET AND THERE ARE NUMEROUS IDENTICAL COMPLAINTS DATING BACK SEVERAL YEARS. THIS LACK OF ACCELERATION HAS OCCURRED FOUR MORE TIMES. THE DEALER HAS BEEN RESPONSIVE AND KEPT MY VEHICLE ON TWO OCCASIONS TO TRY AND DUPLICATE THE EVENT TO NO AVAIL. ON ONE OF THESE OCCASIONS THE DEALER REPLACED THE TRANSFER CASE BUT THIS DID NOT SOLVE THE PROBLEM. FINALLY, THE DEALER CALLED IN THE PORSCHE ZONE MANAGE WHO I AM TOLD WAS WELL AWARE OF THIS CONDITION AND REFERRED TO IT AS A SAFETY FEATURE TO PREVENT UNINTENDED ACCELERATION. HE CLAIMED THAT THIS IS PERFECTLY NORMAL OPERATION. I CALL IT A SAFETY HAZARD. IN FOUR MONTHS I HAVE DRIVEN THE CAR 3200 MILES. THIS SO-CALLED SAFETY FEATURE HAS ENGAGED ON ONLY SIX OCCASIONS, ALWAYS ON LEFT HAND TURNS FROM A COMPLETE STOP. WHEN THIS HAPPENS I NEVER KNOW WHEN THE ACCELERATION WILL CUT OUT OR HOW LONG I WILL NOT BE ABLE TO ACCELERATE. UP TO NOW, THE FEATURE HAS NEVER ENGAGED IN RIGHT HAND TURNS, IN FORWARD OR REVERSE. I HAVE CHECKED THE OWNERS MANUAL CAREFULLY AND THERE IS NO MENTION OF "UNINTENDED ACCELERATION" NOR IS THERE ANY MENTION OF A SAFETY FEATURE PROGRAMMED IN THE CAR. I HAVE REQUESTED THE DEALER TO BY PASS OR ELIMINATE THIS FEATURE BUT THET SAY PORSCHE WON'T ALLOW IT.

PASSENGER WINDSHIELD WIPER CAME OFF SUDDENLY IN USE WHILE ON HIGHWAY SPEED. CAR HAS NEVER BEEN IN A CAR WASH AS DEALER THINKS AND HAS ONLY SIX MONTHS IN SERVICE.THE FORCE BENT SLIGHTLY THE ARM ITSELF AS IT RIPPED OFF.
