Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

AIR BAGS:FRONTAL:DRIVER SIDE:INFLATOR MODULE

Jan 31, 2020
106,857 units potentially affected
The defect: 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.
The risk: 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.
The 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.

The defect: The Gates Corporation (Gates) is recalling certain aftermarket Tru-Flow Water Pumps, part number TFW 41127, sold at certain NAPA Auto Parts and/or installed by automotive service technicians after November 1, 2013 (and manufactured August 2013 through October 2013) that have a black-colored pulley/sprocket or do not have 'US9377' stamped on the water pump housing.

In the affected water pumps, the pulley or sprocket that turns the timing belt may develop microfractures causing the timing belt to fail.
The risk: A failure of the timing belt may cause the engine to shut down, potentially increasing the risk of a vehicle crash.
The remedy: Gates will notify owners, and dealers will replace the water pump, free of charge. The recall began during May 2014. Owners may contact The Gates Corporation at 1-303-744-1911.

TREAD SEPARATION. I WAS DRIVING WESTBOUND ON I-580, APPROXIMATELY 70 MPH, WHEN THE TREAD ON MY RIGHT FRONT TIRE SEPARATED AND THE TIRE BLEW. I WAS LUCKY TO BE ABLE TO PULL OVER TO THE SIDE OF THE ROAD, WITH THE ASSISTANCE OF OTHER AWARE DRIVERS ON THE HIGHWAY WHO ALLOWED ME TO CHANGE LANES AT A REDUCED SPEED. THE TIRE TREAD DAMAGED THE RIGHT FRONT AREA OF MY CAR, CAUSING APPROXIMATELY $4,000 IN DAMAGES, OF WHICH APPROXIMATELY $3,000 WAS COVERED BY MY INSURANCE COMPANY. THE MOST IMPORTANT ISSUE IS SAFETY, NOT MONEY. I COULD HAVE BEEN SEVERELY INJURED OR KILLED AS A RESULT OF THE TIRE FAILURE. THE TIRE HAD A BIG O TIRES BRAND LABEL BUT IT WAS MANUFACTURED BY COOPER. BEFORE THE INCIDENT, THERE WAS NO ABNORMAL USAGE OR WEAR ON THE TIRE, WITH THE EXCEPTION OF ACCELERATED WEAR AT THE PLACE WHERE THE TREAD SEPARATION INITIATED, WHICH WAS CAUSED BY THE SEPARATION. COOPER MIGHT BE THE ONLY TIRE MANUFACTURER THAT DOES NOT USE A BELT WEDGE. THEIR HISTORY OF TREAD SEPARATIONS AND TIRE FAILURES, AND TOTAL DISREGARD FOR THE SAFETY OF THEIR AMERICAN CUSTOMERS SHOULD BE SUFFICIENT TO REMOVE THEIR PRIVILEGE OF DOING BUSINESS IN THE U.S. *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. Older model years have had longer for reports to accumulate.
