What owners actually said
258 reportsPRIOR TO RECALL NOTIFICATION (99V-248) IN REGARDS TO THE STEERING SYSTEM, THE VEHICLE EXPERIENCED FAILURE FROM STEERING FLUID CONTAMINATION WHICH CAUSED LOSS OF STEERING CONTROL AND RESULTED IN VEHICLE COLLISION, INJURIES TO CONSUMERS. (ATTORNEY FOR CONSUMER). *MJS
THERE IS A 2 SEC. DELAY FOR BRAKE RESPONSE WHEN WET. MUCH WORSE THAN ANY OTHER VEHICLE I HAVE DRIVEN. THIS WILL CAUSE ACCIDENTS. VEHICLE WILL NOT STOP IN PUBLISHED DISTANCE WHEN BRAKES ARE WET. NEW BRAKE PAD MATERIAL IS REQUIRED . THERE ARE ALREADY MANY OTHER REPORTS OF THIS SAME PROBLEM IN YOUR DATA BASE.
THE LEFT LOWER CONTROL ARM HAS BEEN REPLACED. THIS IS A VERY COMMON OCCURANCE AMONG A4 OWNERS. AUDI HAS REFUSED TO REPLACE THE RIGHT LOWER CONTROL ARM AFTER IT HAD BEGUN SHOWING SIMILAR PROBLEMS. AUDIWORLD.COM LISTS WELL OVER 50 PEOPLE WHO HAVE HAD CONTROL ARMS REPLACED. I FELT YOU SHOULD BE NOTIFIED.
DURING WET WEATHER, THE BRAKES TAKES SEVERAL SECONDS TO CATCH AFTER THE PEDAL IS DEPRESSED. THIS HAS CAUSED MANY NEAR ACCIDENTS SINCE THIS BEHAVIOR IS NOT NORMAL NOR EXPECTED. DRY WEATHER BRAKING IS JUST FINE. I AM VERY CONCERNED ABOUT THIS PROBLEM AND HAVE CONTACTED AUDI OF AMERICA AND MY DEALER. THEY DO NOT HAVE A SOLUTION…

DURING WET WEATHER, THE BRAKES TAKES SEVERAL SECONDS TO CATCH AFTER THE PEDAL IS DEPRESSED. THIS HAS CAUSED MANY NEAR ACCIDENTS SINCE THIS BEHAVIOR IS NOT NORMAL NOR EXPECTED. DRY WEATHER BRAKING IS JUST FINE. I AM VERY CONCERNED ABOUT THIS PROBLEM AND HAVE CONTACTED AUDI OF AMERICA AND MY DEALER. THEY DO NOT HAVE A SOLUTION FOR THE PROBLEM YET. I NEED HELP!!
I CONTINUE TO HAVE PROBLEMS WITH THE BRAKE SYSTEM ON THIS AUTO, EVEN ON DRY SURFACES. IT APPEARS THAT THE PROBLEM IS A MISALIGNED INTERFACE BETWEEN THE ALL-WHEEL DRIVE (QUATTRO) SYSTEM AND THE ABS. THE PROBLEM IS ONE OF SOFTWARE, NOT HARDWARE, AND AUDI NEEDS TO REPLACE THE APPROPRIATE CHIP.*AK
VEHICLE DOES NOT BRAKE PROPERLY WHEN BRAKES ARE WET. WHEN APPLYING BRAKES VEHICLE CONTINUES TO TRAVEL. THIS PROBLEM HAS BEEN REPORTED TO DEALERSHIP AND MANUFACTURER MANY TIMES. PROBLEM HAS NOT BEEN CORRECTED. *AK THE PROBLEM WAS CORRECTED ON 2000 MODELS BY REDESIGNING BRAKES BUT NO ON EARLIER MODELS. *YH
MY CAR SUFFERS FROM THE SAME PROBLEM AS NHTSA CAMPAIGN 99V248000, BUT IS NOT COVERED AS IT WAS MFD 11/98. THE DEALER HAS AGREED TO REPAIR BUT I WANTED TO NOTIFY NHTSA THAT THE RECALL DOES NOT COVER ALL DEFECTIVE VEHICLES FOR THIS PROBLEM.*AK
BOLT FOR CRUISE CONTROL SERVO FELL OUT RESULTING IN SERVO BECOMING WEDGED IN ENGINE AREA AND CAUSING SUDDEN ACCELERATION OF THE VEHICLE ON HIGHWAY. YH
AFTER DRIVING ON THE HIGHWAY IN THE RAIN, WHEN BRAKES FIRST APPLIED, THE CAR ACCELERATES, THEN BRAKES AFTER 1-2 SECONDS. THIS IS VERY UNNERVING AND THE DEALER SAYS AUDI KNOWS ABOUT THIS BUT THERE IS "NO ADVISORY OR TECHNICAL BULLETIN TO FIX IT" PLEASE HELP. OTHERWISE, THIS CAR IS ONE OF THE BEST.*AK
Official recalls
422V471000 · Air Bags:frontal:driver Side:inflator Module
Jul 1, 2022
Volkswagen Group of America, Inc. (Audi) is recalling certain 1998 Audi A8 and 1997-1998 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 inflator may absorb moisture, causing the inflator to explode or the air bag cushion to underinflate.
Consequence & remedy
Consequence: The inflator could explode during air bag deployment, resulting in metal fragments striking the driver or other occupants. An underinflated air bag may not properly protect the occupant. These scenarios increase the risk of serious injury or death.
Remedy: Dealers will replace the driver's air bag inflator with an alternative inflator of a different design, free of charge. Owner notification letters were sent September 21, 2021. Owners may contact Audi customer service at 1-800-253-2834. Audi's number for this recall is 69BT. The vehicles in this recall were mistakenly omitted from recall 20V-056. All vehicle owners have already been notified by mail and informed that the remedy is available.

Sep 13, 1999
VEHICLE DESCRIPTION: PASSENGER VEHICLES. THE TIE RODS OF THE STEERING ASSEMBLY ARE PROTECTED ON EACH SIDE BY A SEAL TO PREVENT MOISTURE AND DUST PARTICLES FROM ENTERING THE SWIVEL BEARING MECHANISM. IT IS POSSIBLE THAT SOME TIE ROD SEALS MAY NOT SEAL PROPERLY.
Consequence & remedy
Consequence: IF MOISTURE AND/OR DUST PARTICLES ENTER THE SWIVEL BEARING MECHANISM, THE SWIVEL BEARING COULD WEAR OVER TIME DIMINISHING THE STEERING CONTROL OF THE VEHICLE.
Remedy: DEALERS WILL REPLACE THE TIE RODS.

Consequence & remedy
Consequence: THIS CONDITION COULD CAUSE INSUFFICIENT VACUUM TO BE PROVIDED TO THE BRAKE BOOSTER.
Remedy: DEALERS WILL INSTALL A VACUUM BY-PASS SYSTEM INTO VEHICLES OPERATED IN THESE STATES WHICH IS DESIGNED TO PROVIDE SUFFICIENT VACUUM FOR FULL BRAKE ASSIST UNDER ALL WEATHER CONDITIONS.
98V134000 · Engine And Engine Cooling:cooling System
Jun 22, 1998
VEHICLE DESCRIPTION: PASSENGER VEHICLES. IF THE ENGINE BACKFIRES DURING A COLD-START, AN AIR SCREEN WHICH IS LOOSELY SEATED IN THE AIR FLOW METER CAN BECOME DAMAGED.
Consequence & remedy
Consequence: SCREEN PIECES COULD ENTER THE INTAKE AIR FLOW SYSTEM AND PREVENT THE THROTTLE PLATE FROM RETURNING TO ITS FULL IDLE POSITION.
Remedy: DEALERS WILL INSTALL A RETAINING RING TO HOLD THE AIR SCREEN IN PLACE.
