NORMAL DAY TO DAY DRIVING HAS PRODUCED FAILURE OF TWO SETS OF FRONT WHEEL BEARINGS ON THIS CAR. THE ORIGINAL EQUIPMENT MADE NOISE AT ABOUT 30,000 MILES AND FAILED COMPLETELY AT 62,000 MILES. THE SECOND SET I HAVE NOW ARE RUMBLING AND GRINDING NOW AND THEY HAVE ONLY BEEN ON THE CAR FOR 20,000 MILES. CONSEQUENCE OF A WHEEL BEARING FAILURE IS LOSS OF CONTROL (STEERING) OF THE VEHICLE. THIS IS AFTER RUNNING A CAR WEARING EAR PLUGS BECAUSE THE BEARING NOISE MAKES THE INTERIOR NOISE IS SO LOUD THERE COULD BE HEARING LOSS FROM EXTENDED TRIPS. DEALER ONLY REPLACED BEARING AFTER IT FAILED AND WELDED ITSELF TO THE WHEEL HOUSING. I HAVE THE FRIED WHEEL BEARING FROM ONE SIDE AND THE HOUSING IT WELDED ITSELF TO. I ALSO STILL HAVE THE SECOND SET BECAUSE I AM RUNNING ON THEM AND THEY ARE MAKING THE SAME RUMBLING, MOANING, GRINDING NOISE THE FIRST SET MADE. *NM

21V470000 · Air Bags:frontal:driver Side:inflator Module

Jun 23, 2021

Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2000-2001 Audi TT Coupe, TT Roadster, 2000-2002 A4, and S4 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 airbag inflator with an alternative inflator, free of charge. Owner notification letters were mailed November 2, 2021. Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 69CJ.
