THE PORSCHE CAYENNE IS NOTORIOUS FOR DRIVE / CARDAN SHAFT FAILURES. HAD BAD DRIVE SHAFT NOISES, AND SUBSEQUENT PREMATURE FAILURE, IT WAS A WORN CENTER SUPPORT DAMPENER AND A FAULTY CENTER SUPPORT BEARING. I EXPERIENCED BANGING, BUMPING, GRINDING NOISES FROM MY PORSCHE CAYENNE AND WAS UNAWARE AT THE TIME IT WAS THE DRIVE SHAFT. I HAVE OUTLINED THE NOISES AND CAUSES BELOW: - A CLANKING OR CLUNKING NOISE WHILE ACCELERATING OR FROM DECELERATION TO ACCELERATION AROUND 35TO 40MPH AND WHILE CAYENNE WAS SHIFTING FROM 2ND TO 3RD TO 4TH GEAR. AROUND 5TH AND 6TH GEAR GOING AROUND 50-60 MPH IT STOPPED. IF I KEPT THE RPM UNDER 200 IT SEEMED TO RUN OK, NO ISSUE, BUT IF I PRESSED THE ACCELERATOR HARD OR GUNNED IT, IT WENT HAYWIRE. IT WAS THE RESULT OF A WORN AND DAMAGED DAMPENER OR DIAPHRAGM LOCATED ON THE CENTER SUPPORT BEARING. THIS CONDITION WILL ALLOW FOR THE DRIVE SHAFT TO TRAVEL UP AND DOWN WITH VARIATIONS IN DRIVE LINE TORQUE. THIS MOVEMENT WILL PRODUCE A LOUD CLANKING OR CLUNKING SOUND AND MAKE FOR A VERY UNCOMFORTABLE RIDE. I LATER FOUND OUT THAT THIS CONDITION IS ONE OF THE MOST COMMON FAILURES ON THE CAYENNE DRIVE SHAFT, ALL MODELS 2003 TO 2006. THIS SHOULD BE A RECALL AND FREE FIX BY PORSCHE BECAUSE IT HAS HAPPENED TO SO MANY OF THE VEHICLES AND MODEL YEARS STATED ABOVE! BUT NO, PORSCHE QUOTED ME $2,500 TO FIX IT. NOT FIX THE PROBLEM AREA, THE HARD RUBBER DAMPENER ON THE CENTER SUPPORT SHAFT OF THE POWER TRAIN, WHICH BY THE WAY IS POSSIBLE. NO, PORSCHE WOULD ONLY REPLACE THE ENTIRE POWER TRAIN FOR $2,500.

POWER TRAIN:AUTOMATIC TRANSMISSION

**UNCONTROLLED ACCELERATION** CAYENNE S ACCELERATED UNCONTROLLABLY WHILE DRIVING. WHILE DRIVING AT APPROX 60 MPH, I ENCOUNTERED TRAFFIC AHEAD AND TOOK MY FOOT OFF THE ACCELERATOR, HOWEVER THE CAR BEGAN ACCELERATING. I TRIED LIFTING THE PEDAL WITH MY FOOT, NO LUCK, APPLIED THE BRAKES AND THE CAR SLOWED, HOWEVER, WHEN I REMOVED MY FOOT FROM THE BRAKE, THE CAYENNE CONTINUED TO ACCELERATE. THE CRUISE CONTROL HAD NOT BEEN ACTIVATED AND WAS OFF. I KEPT PRESSING THE GAS PEDAL AND RELEASING IT AT LEAST A DOZEN TIMES AND FINALLY THE CAYENNE STOPPED ACCELERATING ON ITS OWN, ONLY TO LOSE ANY CONTROL TO ACCELERATE. I COASTED INTO A PARKING LOT AND STOPPED THE CAR. TURNED IT OFF AND RESTARTED - I WAS ABLE TO DRIVE, HOWEVER ACCELERATION WAS VERY SLOW AND GEAR INDICATOR ON THE DASH CLUSTER DISPLAYED A BLACK 'D' IN AN ORANGE SQUARE. THIS IS A SYMBOL THAT DOES NOT EXIST IN THE OWNERS MANUAL. THE CAR SHIFTED THROUGH GEARS NORMALLY. THE RAPID UNCONTROLLED ACCELERATION REPEATED ITSELF AND I WAS ABLE TO PULL INTO ANOTHER PARKING LOT, SLOWING AND STOPPING THE CAR THANKSTO MASSIVE 14" FRONT BRAKES WITH 6 PISTON CALIPERS AND 13"+ REAR BRAKES WITH 4 PISTON CALIPERS. I TURNED THE CAR OFF FOR A FEW MINUTES AND RESTARTED. GEAR SELECTION INDICATOR APPEARED NORMAL AND I WAS ABLE TO DRIVE OFF, HOWEVER ACCELERATION WAS STILL VERYSLOW. DROVE HOME WITH THE RAPID ACCELERATION REPEATING ITSELF AGAIN AND THEN STOPPING AFTER A FEW MILES. THE ONLY REASON THIS DID NOT CAUSE A CRASH IS THE MASSIVE BRAKING POWER OF THE CAYENNE AND ASTUTE DRIVING. I RAN DIAGNOSTIC SOFTWARE WHEN I MADE IT HOME AND THERE WAS AN "ACCELERATOR MODULE" FAILURE REPORTED. THE TAIL LIGHTS, ALARM, CENTRAL LOCKING, AND THE ABILITY TO OPEN THE TAILGATE AT ALL HAVE ALSO FAILED - "REAR LIGHTING CONTROL MODULE" FAILURE. SO WHILE DRIVING, MY TAIL LIGHTS FAILED, CAR ACCELERATED UNCONTROLLABLY AND FAILED TO ACCELERATE IN A SAFE NORMAL MANNER. THIS IS A MAJOR SAFETY ISSUE AND SHOULD BE PROMPTLY ADDRESSED!

POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM)

DT: THE CONTACT OWNS A 2004 PORSCHE CAYENNE S. WHILE DRIVING UP A HILL AT SLOW SPEEDS THE VEHICLE WILL FEEL AS IF THE TRANSMISSION IS GOING IN AND OUT OF GEAR. THIS CAUSES THE VEHICLE TO JERK, AND MAKES IT DIFFICULT TO CONTROL THE VEHICLE. THIS HAPPENS INTERMITTENTLY WHETHER IT IS WARMER OR COLDER TEMPERATURES. THE SERVICE DEALER REPROGRAMMED THE ELECTRONIC CONTROL MODULE, , BUT THIS DID NOT REMEDY THE PROBLEM. THE SERVICE DEALER ATTEMPTED TO REPAIR THE PROBLEM NUMEROUS TIMES. THE ATTEMPTS TO REPAIR THE PROBLEM INCLUDED, UPDATING AND THE REPLACEMENT OF THE TRANSMISSION CONTROL UNIT. THIS STILL DID NOT REMEDY THE PROBLEM. THE DEALER REPORTED THE PROBLEM TO THE MANUFACTURER, AND THEY SENT A TECHNICIAN TO DETERMINE THE PROBLEM. THE TECHNICIAN REPRODUCED THE PROBLEM, AND SAID THAT IT WAS A CONDITION OF HILL HOLDER FUNCTION WHICH HOLDS THE VEHICLE IN PLACE TO APPROXIMATELY 800-1100 RPMS, AT WHICH IT WILL START TO ENGAGE THE TRANSMISSION. THE MANUFACTURER STATED THAT THIS WAS A NORMAL OPERATING PROCEDURE FOR THIS TYPE OF VEHICLE WHEN THE VEHICLE WA SCOLD. THE CONTACT REQUESTED FOR THE MANUFACTURER TO SUBMIT THE REASON WHY THIS WAS NORMAL OPERATING PROCEDURES FOR THE VEHICLE. THE REMEDY FROM THE MANUFACTURER WAS FOR THE CONTACT TO ACCELERATE MORE WHEN GOING UP A HILL. THE SECOND EXPLANATION THE MANUFACTURER OFFERED WAS THAT THE JERKING OF THE VEHICLE WAS CAUSED BY OUTSIDE TEMPERATURES. THE CALIFORNIA NEW MOTOR VEHICLE BOARD REQUESTED THAT THE SECOND EXPLANATION BE PUT INTO WRITING, BUT THE MANUFACTURER REFUSED. ANOTHER SAFETY CONCERN BOTHERING THE CONTACT WAS THAT WHILE DRIVING AND UPON ACCELERATION THE VEHICLE WILL STALL. WHEN ACCELERATING NOTHING WILL HAPPEN, THE ENGINE WILL COMPLETELY LOSE POWER. THE SERVICE DEALER STATED THIS WAS TRANSMISSION CONTROL., BUT THE REPAIRS DID NOT SOLVE THE PROBLEM.
