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.

Latest Jun 22, 2018
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.

The defect: Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2005-2008 Audi A4 Sedan, A4 Avant, S4 Avant and S4 Sedan, 2007-2008 RS4 Sedan, 2004 RS4 Cabriolet, 2007-2009 A4 Cabriolet and S4 Cabriolet, 2005-2011 A6 Sedan, 2006-2011 A6 Avant, and 2007-2011 S6 Sedan vehicles. These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the passenger frontal air bag, these inflators may explode due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.
The risk: An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
The remedy: Audi has notified owners, and dealers will replace the passenger frontal air bag with an alternate remedy part, free of charge. The recall began June 29, 2018. Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 69R7. Note: This recall supersedes recalls 16V382, 17V032 and 18V004 and includes vehicles that may have had their air bag previously replaced under one of those campaigns.

Crash reported1 injury reported

The contact owns a 2008 Audi A4. The contact received an unknown recall notice related to the air bags. The contact scheduled an appointment at a dealer and had the recall serviced. The contact then stated that while idle in the parking lot of a hospital, a speeding vehicle clipped the front end, driver's side of her vehicle, which caused the entire front bumper to detach from the vehicle. The driver also hit a gate, guardrail, and utility box in the parking lot. The air bags did not deploy upon impact. The contact was then treated at the hospital for an injury to her neck and left shoulder. The contact sustains severe headaches weeks after the accident. The contact received an X-ray and had been assigned to physical therapy for the next few months. The other driver was not injured as a result of the accident. A police report was filed. The vehicle was initially towed to an independent mechanic and was later towed to a storage unit. The contact family member, who is mechanically inclined, stated that the vehicle's air bag sensors were defective. The vehicle had yet to be diagnosed or repaired by dealer. The dealer was notified of the failure and referred the contact to the manufacturer; the manufacturer gave the contact a case number. The failure mileage was approximately 140,000.

Audi is wanting me and another driver to drive 2.5 hours to their dealer drop off the car for repairs, then drive back. Then after the repairs are complete make that trip again. They want us to spend 20 man hours driving, plus gas, food, and mileage. None of this is reimbursed. I have called and written Audi several times with the same answer. This is unreasonable when they have a local VW dealer and other Audi certified mechanics that can do the job within 20 minutes. Our zip code is [XXX] .

While I was driving on the highway the sunroof (just the window) flew off. I had the sliding roof door closed and only heard a gust of wind initially thinking it just became ajar somehow, but nope the entire window was gone, like the adhesive deteriorated I assume. The sunroof mechanism works perfectly fine. Fortunately if was really early in the morning and to my knowledge no one was on the road, but if they had been an injury or death could have happened!

I HAD JUST PUT $35 IN GASSED THE CAR STILL SAID I NEEDED GAS AND THAT I HAD ZERO MILES LEFT OF GAS I MADE A TRIP THAT WAS ABOUT 45 MILES IN DISTANCE. MY CAR WAS THEN PARKED AND TURNED OFF FOR ABOUT 3 TO 4 HOURS THEN IT HAD TROUBLE STARTING AT FIRST BUT TURNED ON AND I PROCEEDED ONTO THE FREEWAY WHICH WAS ACROSS THE STREET FROM THE PARKING LOT I PARKED INSIDE OF. IT WAS ABOUT 9:00 PM AND THANKFULLY THERE WAS NOT A LOT OF CARS OUT. THE ENTRANCE OF THIS FREEWAY CONSIST OF ONE MEDIUM SIZED STEEP HILL WHICH REMAINS TRAVELING UPWARD ONTO A MOUNTAIN WHEN MY CAR SUDDENLY SHUT OFF MY 3 YEAR OLD DAUGHTER AND I WERE IN THE CAR AND THANKFULLY WE WERE ON THE LAST LANE DUE TO THE FACT THAT WE WERE BARELY ENTERING THE FREEWAY. I PARKED ON THE RIGHT SIDE SKIRT I HAD JUST REPLACED THAT BATTERY EARLIER THAT WEEK (NO MORE THAN 5 DAY BEFORE). I HAD A SMALL GAS CAN IN MY TRUNK AND HAD SOMEONE GO TO THE GAS STATION AND BRING ME THE GALLON OF GAS WHICH I EMPTIED INTO MY CAR AND IT TURNED ON. AT TIMES THE CAR DOES SMELL LIKE GASOLINE ESPECIALLY IF I JUST PUT GAS. IT DOESN'T MATTER HOW MUCH GAS I FILL UP MY TANK WITH IT WILL INDICATE I HAVE 0 MILES OF GAS IN THE SCREEN AND THE FUEL GAUGE WILL NOT GO BELOW THE MIDDLE INDICATOR AND WILL NEVER SHOW ABOVE 3/4 FULL. MY TPMSA IS ALWAYS INDICATING A PROBLEM WHEN THE I HAVE A MECHANIC SEE IT AND HE ASSURED ME IT'S IN GOOD CONDITION

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.
