2004 PORSCHE CAYENNE S Engine And Engine Cooling Problems

PORSCHE KNOWINGLY MANUFACTURED CAYENNE MODEL VEHICLES WITH PLASTIC COOLANT TUBES THAT DEGRADE AND FRACTURE CAUSING ENGINE COOLANT TO LEAK INTO THE ENGINE, POTENTIALLY LEADING TO SIGNIFICANT ENGINE DAMAGE. PORSCHE HAS KNOWN ABOUT THIS DEFECT AND FAILED TO MAKE CONSUMERS AWARE OF THE POTENTIAL FAILURE DESPITE THE RISK TO THE OWNERS SAFETY AND POCKETBOOK. *KB

TL* THE CONTACT OWNS A 2004 PORSCHE CAYENNE S. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 50 MPH, AN OVERHEATING INDICATOR LIGHT BEGAN TO ILLUMINATE ON THE INSTRUMENT PANEL. THE VEHICLE WAS TAKEN DIRECTLY TO AN INDEPENDENT REPAIR SHOP WHERE ENGINE COOLANT WAS ADDED TO THE VEHICLE. WHILE ADDING THE COOLANT, THE TECHNICIANS NOTICED THAT THE COOLANT WAS LEAKING OUT THROUGH ITS PLASTIC TUBING. THE VEHICLE WAS THEN TOWED TO AN AUTHORIZED DEALER WHERE THE PLASTIC TUBING FOR THE ENGINE COOLANT WAS BEING REPLACED WITH ALUMINUM TUBING. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE, BUT OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS 54,500.

**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...

DT*: THE CONTACT STATED THE VEHICLE PERFORMS AS IF IT WILL STALL WHILE ACCELERATING IN TRAFFIC. THE VEHICLE HAS NEVER ACTUALLY STALLED, BUT HESITATES DURING ACCELERATION. THE HESITATION OCCURS MOSTLY WHEN VEHICLE IS MAKING TURNS. THIS IS A RECURRING INCIDENT WHICH OCCURS DAILY.

PORSCHE-04 CAYENNE ON OCCASIONS STALLS ON TURNING AND TOUCHING BRAKE AND TWICE ON THE FREEWAY GOING STRAIGHT BUT BRAKING AND PUSHING ON THROTTLE NO POWER FOR A FEW SECONDS. *JB

DT: THE AIR BAG AND THE CHECK LIGHTS CAME ON. THE CONSUMER CONTACTED THE DEALER AND THEY SAID THEY COULD NOT SERVICE THE CAR UNTIL 10/17/2005. CALLED PORSCHE CUSTOMER SERVICE, AND THEY SAID THEY COULD HELP. THE CONSUMER BELIEVED THIS WAS A SAFETY HAZARD, AND HE DID NOT WANT TO DRIVE THE CAR.*AK *JB
