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.

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.
