The turbo sounds like it's not going in/out of gear, oil going into spark plugs, radiator fluid leaking system getting real hot. Low engine poer picking up speed an issue. Air bag rear brake light malfunction, oil pressure not correct
ENGINE COOLANT AND ENGINE LIGHT ETC CAME ON. THE VEHICLE WAS ON THE HIGHWAY. I HAVE A SMALL CHILD. BASED ON THE AUDI MESSAGE MY VEHICLE COULD CATCH ON FIRE.PLEASE SEND ME INFO TO HAVE THIS PROBLEM CORRECTED.
MY CAR HAS A LEAKING HIGH PRESSURE FUEL LEAK FROM THE HIGH PRESSURE HOSE RIGHT AT THE TOP OF THE ENGINE BLOCK AT THE REAR OF THE ENGINE. THE STEEL LINE CONNECTS DIRECTLY TO THE FILTER AND IS LEAKING FROM THE STAINLESS STEAL LINE. THE POWER STEERING METAL HOSE LINES ARE INCORRECT FROM THE FACTORY AND DO NOT SUPPLY ENOUGH PRESSURE IN THE LINE TO KEEP THE STEERING WHEEL FROM A VERY HARSH LOW SPEED SHUDDER WHEN TURNING. THE LOWER CONTROL ARM BUSHINGS FAIL AT VERY LOW MILEAGE. NONE OF THESE ISSUES HAVE BEEN ACKNOWLEDGED ON THIS YEAR CAR. THIS MODEL AUDI IS AN ABSOLUTE LEMON HAVING MULTIPLE ISSUES AND EXTREME REPAIRS AND HUGE COSTS WHEN TRYING TO FIX THEM. I HAVE THE PAPER WORK FOR THESE FIXES AND WHAT IT TAKES TO REPAIR THEM CORRECTLY. I HAVE ALREADY HAD THIS CAR REPAIRED FROM AUDI FOR THE PISTON RING OIL FAILURE WHICH THEY HAD TO REPLACE PER THE LAWSUIT THEY WERE HIT WITH AND STILL DENIED ANY WRONG DOING. PLEASE FORCE THIS COMPANY TO RIGHT THESE ISSUES THEY IGNORED IN THE FACE OF PROFITS INSTEAD OF DOING RIGHT BY THE CONSUMER.
SINCE THE MOMENT I PURCHASED THIS VEHICLE IN 2012, I'VE HAD NOTHING BUT CONSTANT ISSUES. THIS VEHICLE HAS STOPPED IN THE MIDDLE OF THE STREET ON THE FREEWAY (SURPRISED I WAS NOT HURT BECAUSE OF THIS). I'VE HAD ENGINE LIGHTS ON, CHECK OIL LEVEL LIGHTS ON, ALTERNATOR GOING BAD, ESP LIGHTS ON, BEARINGS REPLACEMENT. YOU NAME IT, ITS HAPPENED. I TOOK MY AUDI IN FOR AN APPRAISAL AND TURNS OUT THE TRANSMISSION IS GOING BAD, HAD WARRANTY AND AUDI SERVICES DID NOT MENTION ANY ISSUES WITH MY TRANSMISSION, WASN'T UNTIL MY WARRANTY HAD EXPIRED WHEN I FOUND THIS OUT. THIS VEHICLE SHOULD BE RECALLED.
THE HIGH-PRESSURE FUEL PUMP FAILED, WHICH CAUSED THE VEHICLE TO BUCK SUDDENLY AND STALL WHILE DRIVING IN TRAFFIC.
TWO FAULTY MIS FIRES CAUSED CAR TO MISFIRE AND RUN ROUGH AND JOLT. CAR WAS TOWED TO THE CLOSEST AUDI DEALERSHIP FOR REPAIRS. SUBSEQUENTLY, WITHIN THE NEXT 9 MONTHS, THE CARE AGAIN EXHIBITED CLOSE TO THE SAME SYMPTOMS AND THE CAR WAS AGAIN TOWED TO THE CLOSEST AUDI DEALERSHIP. THIS TIME, THE INTAKE MANIFOLD WAS CRACKED AND WAS REPLACED. WITH A SERVICE BULLETIN OUT ON THIS VEHICLE ON THESE EXACT ISSUES, I WAS STILL CHARGED A $250 DEDUCTIBLE PER INCIDENT ($500 TOTAL) ON MY EXTENDED WARRANTY TO REPLACE BOTH THE INJECTORS AND THE INTAKE MANIFOLD. ACCORDING TO THE SERVICE BULLETIN, I SHOULD NOT HAVE BEEN CHARGED.
RECENTLY DONE OIL CHANGE WITH SYNTHETIC OIL (AUDI RECOMMENDED) WHICH SHOULD LAST FOR 10,000 MILES BEFORE ANOTHER OIL CHANGE IS NEEDED. UNFORTUNATELY AFTER A MONTH AND HALF OF DRIVING OIL LEVELS ARE SHOWING HALF OF THE OIL GONE. ENGINE IS MAKING NOISE AND LOT OF CO2 BEING CLOGGED UP. RUNNING HEAVY CAUSES TO USE LOT OF FUEL. FEELS AS IF ENGINE MAY GET TOO HOT AFTER EATING UP EXCESS AMOUNT OF OIL. *TR
I WAS DRIVING MY NEW 2009 AUDI A4 WHICH HAD LESS THAN 3500 MILES ON IT AT THE TIME WHEN FIRST THE TRANSMISSION CHANGES BEGAN TO BE VERY ABRUPT. I THOUGHT NOTHING OF IT AT FIRST AND TRAFFIC ON THE WESTSIDE HIGHWAY IN NEW YORK CITY WAS FAIRLY CONGESTED SO THE SPEEDS WERE NOT THAT HIGH. SUDDENLY, THE TRANSMISSION STOPS SHIFTING ALL TOGETHER AND ALL THE LIGHTS CAR'S DASHBOARD TURN ON BEFORE THE ENGINE SIMPLY SHUTS OFF I ROLL TO A HALT IN THE CENTER LANE OF THE WESTSIDE HIGHWAY AND USE THE BATTERY TO TURN ON MY HAZARD LIGHTS. I REPEATEDLY TRIED TO RESTART THE ENGINE AND IT WOULD START FOR ABOUT A SECOND BEFORE THE WHOLE CAR BEGAN TO VIBRATE HEAVILY BEFORE THE ENGINE WOULD SHUT DOWN. THE POLICE WERE CALLED AND THEY ESCORTED THE TOW-TRUCK OFF THE HIGHWAY. THE CAR WAS LOCKED IN THE TOW-TRUCK DEPOT UNTIL THE NEXT MORNING WHEN IT WAS GIVEN TO THE AUDI SERVICE DEPARTMENT WHERE THEY RAN TESTS AND DETERMINED THAT THE FUEL PUMP HAD BROKEN. THEY REPLACED THE PUMP AND THE CAR WAS RETURNED TO ME A FEW DAYS LATER. *TR
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
