WAS DRIVING ON FREEWAY FOR A FEW HOURS DURING WHICH CAR WAS RUNNING FINE, AND CAR SUDDENLY LOST POWER JUST AFTER I GOT OFF FREEWAY AND APPROACHED A MOUNTAIN ROAD INCLINE. THERE WAS NO WARNING LIGHT, OR PRIOR SYMPTOMS TO ENGINE FAILURE, IT JUST STOPPED. WITH HELP, I WAS ABLE TO GET CAR OUT OF THE MIDDLE OF THE ROAD AND TO SAFETY. TRIED TO TROUBLESHOOT, USED ENGINE ERROR CODE READER, AND NO FAULT CODES FOUND. PERFORMED BASICS CHECKED FOR POTENTIAL FUEL VAPOR LOCK DUE TO ALTITUDE; CHECKED OIL, COOLANT AND FUEL LEVELS- AND ALL LEVELS WERE OK. BATTERY WAS FUNCTIONING - AS RADIO, LIGHTS WORKED. CAR HAS BEEN CONSISTENTLY SERVICED AND MAINTENANCE WAS CURRENT. CAR WAS TOWED TO NEAREST DEALER, DIAGNOSIS BY DEALER FUEL PUMP FAILURE DUE TO CLOGGED FUEL FILTER. MY ISSUE IS THAT AUDI DOES NOT INDICATE SERVICE MAINTENANCE FOR FUEL FILTER. THERE IS NOT ANY MAINTENANCE RECOMMENDATIONS OR GUIDANCE IN EITHER THE OWNER'S MANUAL OR PUBLISHED LIST OF RECOMMENDED SERVICES TO REPLACE OR CHECK FILER. THERE ALSO WERE NOT ANY WARNING LIGHTS, FAULT CODES OR INDICATIONS TO WATCH FOR. I FEEL THAT IT IS NEGLIGENT OF THE MANUFACTURER TO NOT INDICATE ANY SERVICE INTERVAL TO CHANGE FUEL FILTER IN ORDER TO PREVENT FUEL PUMP FAILURE, AND TO ENSURE THE SAFE OPERATING CONDITIONS OF THE VEHICLE. THE CAR LOST POWER ON A WINDING MOUNTAIN ROAD AND PUT ME AT DANGER WITHOUT WARNING. I AM CURIOUS IF THIS FUEL PUMP INCIDENT COULD BE ASSOCIATED WITH KNOWN FUEL PUMP ISSUES, NHTSA #PE08027. KEY SIDE NOTES, WHILE I AM THE SECOND REGISTERED OWNER, THIS CAR WAS PURCHASED BY MY FATHER WHO WAS THE ORIGINAL OWNER, BUT FOR INSURANCE AND REGISTRATION PURPOSES THE VEHICLE WAS TRANSFERRED OVER TO ME, BUT I HAVE ALL ORIGINAL RECORDS OF THE VEHICLE AND CAN VERIFY ALL MAINTENANCE SERVICES HAVE BEEN PERFORMED. *JS

WHILE DRIVING THROUGH A PARKING LOT, MY 2004 AUDI A4 1.8 CABRIOLET SUDDENLY ACCELERATED FOR NO APPARENT REASON. I WAS ABLE TO SHUT IT DOWN AND CHECKED TO MAKE SURE THE FLOOR MAT WAS NOT INTERFERING WITH THE GAS PEDAL. I RESTARTED THE CAR AND DROVE TO MY NEXT LOCATION WITHOUT INCIDENT. HOWEVER, AFTER LEAVING MY NEXT LOCATION AND PULLING OUT ONTO THE MAIN ROAD THE CAR STARTED ACCELERATING AGAIN AND WAS DIFFICULT TO CONTROL. THE MORE I APPLIED THE BRAKE, THE MORE THE ENGINE RACED. AFRAID OF CAUSING AN ACCIDENT IN RUSH HOUR TRAFFIC, I WAS ABLE TO PULL INTO A PARKING LOT AND TURN OFF THE CAR. THIS ALSO HAPPENED TO ME ABOUT A YEAR AGO, BUT I ASSUMED IT WAS THE CAR MAT BECAUSE IT NEVER HAPPENED AGAIN UNTIL FEBRUARY OF THIS YEAR. AFTER BEING MADE AWARE OF THE TOYOTA PROBLEM, I DECIDED TO RESEARCH A BIT AND HAVE DISCOVERED MINE IS NOT AN ISOLATED AUDI PROBLEM. I'M HONESTLY AFRAID TO DRIVE THE CAR OUT OF CONCERN THIS MAY HAPPEN AGAIN. *TR
