BY MANUALLY PULLING UP THE CLUTCH, IT WILL ENGAGE. SINCE THIS IS AN INTERMITTENT PROBLEM (SAME PROBLEM OCCURRED AT 1500 MILES, AUDI IS REFUSING TO FIX THE PROBLEM, I REFUSE TO DRIVE AN UNSAFE VEHICLE WHOSE ABILITY TO SHIFT CAN FAIL AT ANY TIME.
THE HEADLIGHTS DO NOT PROVIDE SUFFICIENT ILLUMINATION ON LOW OR HIGH BEAM. DRIVER WAS NOT ABLE TO AVOID HITTING A HERD OF ELK BECAUSE OF THE LIGHTING. THE DEALER IS NOT ABLE TO CORRECT THE PROBLEM.
THE DEFECTIVE WAS REPLACED WITH ANOTHER WINDSHIELD THAT WAS OF THE SAME INFERIER QUALITY WHICH I WAS INFORMED WAS THE ONLY POSSIBLE SOLUTION. THIS CAR IS UNSAFE TO DRIVE ESPECIALLY AT NIGHT.

I WAS BACKING UP IN DRIVEWAY IN FRONT OF ANOTHER VEHICLE WHICH WAS PARKED IN FRONT OF A HOUSE. MY CAR GAVE A SLIGHT LURCH AND THE MOTOR REVVED UP. I IMMEDIATELY LOOKED BECAUSE I THOUGHT I MUST HAVE MY FOOT ON THE ACCELERATOR. MY FOOT WAS ON THE BRAKE. HOWEVER, THE CAR SUDDENLY ACCELERATED BACKWARD INTO THE TRUCK, DRIVING IT 15 FEET INTO THE PORCH STEPS. THE PICKUP TRUCK WAS TOTALLED AND THE STEPS COMPLETELY DEMOLISHED. WE IMMEDIATELY CONTACTED TISCHER, OUR INSURANCE COMPANY AND ATTEMPTED TO CONTACT SOMEONE AT AUDI. IT WAS A FULL 2 WEEKS BEFORE SOMEONE FROM AUDI CALLED US BACK. FINALLY, AN AUDI REP MET US TO INSPECT THE CAR. AUDI DETERMINED THAT IT WAS "OPERATOR ERROR" AND ABSOLUTELY REFUSED TO DO ANYTHING. WE'RE HAVING OUR INSURANCE COMPANY REPAIR THE AUDI, AND WE WILL THEN TRADE IT IN ON OUR SECOND CHOICE CAR--A BMW. I SIMPLY COULD NOT DRIVE THE AUDI AGAIN, AND THANK GOD THAT NO ONE WAS INJURED. I BELIEVE THAT AUDI'S ARE VERY DANGEROUS AND SHOULD BE TAKEN OFF THE ROAD UNTIL THIS "SUDDEN ACCELERATION" PROBLEM HAS BEEN SOLVED. IF IT WERE "OPERATOR ERROR" AS THEY CLAIM--WHY DOES ONLY HAPPEN IN AUDI'S??? PLEASE DO EVERYTHING YOU CAN TO HAVE THIS PROBLEM CORRECTED BEFORE MORE PEOPLE ARE MAIMED, INJURED AND KILLED. *AK

420V056000 · Air Bags:frontal:driver Side:inflator Module
Jan 31, 2020
Volkswagen Group of America, Inc. (VW) is recalling certain 2000-2001 TT Roadster, 2000 TT Coupe, 1999 Audi A8, 1998-2000 Audi A6, and 1999-2000 Audi A4 vehicles equipped with Non-Azide Driver air bag Inflators (NADI) that do not contain phase stabilized ammonium nitrate (PSAN) propellant. Due to a manufacturing issue, the NADI inflators may absorb moisture, possibly causing the air bag to deploy improperly in the event of a crash.
Consequence & remedy
Consequence: In the event of a crash necessitating air bag deployment, the air bag may not properly protect the occupant, increasing the risk of serious injury or death.
Remedy: Dealers will replace the driver frontal air bag inflator with an alternative inflator when the parts become available, free of charge. Owner notifications were mailed September 21, 2021. Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 69BT.
