2004 Porsche Cayenne Speed Control & Cruise Problems

TL*THE CONTACT OWNS A 2004 PORSCHE CAYENNE. WHILE DRIVING APPROXIMATELY 60 MPH, THE CONTACT HEARD A TICKING NOISE FOLLOWED BY A LOUD, THUMPING NOISE WHICH CAUSED THE VEHICLE TO ACCELERATE. THE LOCAL AUTHORIZED DEALER STATED THAT THE BEARING AND DRIVE TRAIN NEEDED TO BE REPLACED. THE MANUFACTURER HAD NOT BEEN NOTIFIED. THE VEHICLE WAS BEING REPAIRED BY THE DEALER. THE VIN WAS UNAVAILABLE. THE CURRENT MILEAGE WAS APPROXIMATELY 93,000. THE FAILURE MILEAGE WAS APPROXIMATELY 90,000.

I OWN A 2004 PORSCHE CAYENNE S AND FROM THE VERY FIRST DAY OF OWNERSHIP THE CAR HAS A SERIOUS HESITATION PROBLEM WHEN ACCELERATING. I HAVE HAD THE CAR SERVICED AT THE PORSCHE DEALERSHIP (MCKENNA IN NORWALK, CA) AND THEY TELL ME THAT THEY ARE VERY AWARE OF THE PROBLEM AND THERE IS NO WAY TO FIX IT. MANY, MANY CAYENNE OWNERS ARE HAVING THE SAME PROBLEM AND PORSCHE REFUSES TO FIX THE PROBLEM. I HAVE HAD SEVERAL NEAR-MISS COLLISIONS BECAUSE OF THE CARS HESITATION WHEN ACCELERATING. PLEASE HELP AND LET ME KNOW THE STATUS OF THIS DANGEROUS ISSUE. THANKS, DEREK DEAN. *NM

WHILE TURNING ACROSS TRAFFIC FROM E 2ND AVE ONTO JOSEPHINE ST. THE ACCELERATOR PEDAL WAS DEPRESSED TO THE JUST ABOVE THE FLOOR AND NO DISCERNABLE ACCELERATION RESPONSE WAS NOTICEABLE FOR A SECOND OR TWO. WHEN THERE WAS AN ACCELERATION RESPONSE IT WAS AN EXPLOSIVE, 'OFF TO THE RACES' ONE. THIS INCIDENT TOOK PLACE AFTER THE DEALER ADVISED THAT: UNOFFICIAL FIXES (DME UPDATE AND TRANSMISSION ADAPTATION) ISSUE HAD BEEN IN PLACE SINCE THE DELIVERY OF THE VEHICLE; VEHICLE HAD BEEN INTO THE DEALER TO EVALUATE/ADDRESS THIS ISSUE THREE TIMES; ON THE THIRD VISIT THE TRANSMISSION CONTROL MODULE WAS REPLACED/UPDATED/ADAPTED AND DME CONTROL UNIT WAS REMAPPED.*AK

WHILE MERGING FROM HIGHWAY 141 ONTO I-70 THE ACCELERATOR PEDAL WAS DEPRESSED TO ACCELERATE FROM HIGHWAY SPEED TO MERGE INTO INTERSTATE TRAFFIC AND NO NOTICEABLE ACCELERATION WAS APPARENT. THE EXTREMELY CONCERNING ABOUT THIS INCIDENT WAS THAT THIS MERGE WAS BEING EXECUTED BETWEEN TWO 18-WHEELERS. WHILE THERE WAS AMPLE SPACE TO MERGE IF THE VEHICLE HAD RESPONDED WITHOUT HESITATION TO ACCELERATOR PEDAL INPUTS, THE EXPERIENCED HESITATION MADE THE MERGE DICEY.*AK

WHILE PULLING OUT FROM A PARKING LOT INTO MAJOR CITY STREET THE VEHICLE HESITATED TO RESPOND TO ACCELERATOR INPUT WITH APPROACHING TRAFFIC.*AK THE VEHICLE MOVED OFF FROM A STOP AND INTO THE CLOSEST LANE FINE BUT WOULD NOT ACCELERATE AS MORE ACCELERATOR PEDAL WAS APPLIED. THERE WAS NOTICEABLE DELAY/HESITATION, AS TRAFFIC BORE DOWN ON ME, BEFORE THE CAYENNE DECIDED TO ACCELERATE. CONTACTED DEALER WHO NOTED THAT THERE WAS AN UNOFFICIAL FIX THAT MAY ADDRESS THE ISSUE.

CUSTOMER CAMPAIGN NOTICE RECEIVED REGARDING MAIN WIRING HARNESS ROUTING. AS WELL AS PROBLEMS WITH ENGINE NOT RESPONDING TO ACCELERATOR PEDAL.*MR THE VEHICLE'S ENGINE UNEXPECTEDLY DOES NOT RESPOND TO INPUT ON THE ACCELERATOR PEAL. THIS PROBLEM HAS OCCURRED SO MANY TIMES THAT THE CONSUMER DECIDED TO PUT THE VEHICLE IN STORAGE AND NO LONGER DRIVE THE VEHICLE. THE CONSUMER HAS COMPLAINED TO THE DEALER SEVERAL TIMES TO NO AVAIL. THE DEALER INSIST THAT THIS IS A CHARACTERISTIC OF THE VEHICLE. *NM
