NHTSA Complaint #10303704 — 2004 PORSCHE CAYENNE S

**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! *TR
