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 Mar 6, 2000
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.

I OWN TWO OF THE ORIGINAL AUDI S4'S, BOTH 1993 MODELS. MY DAUGHTER WAS DRIVING ONE OF THESE CARS IN 2007 AND THE THROTTLE STUCK OPEN SO THAT THE ENGINE RACED UNCONTROLLABLY. SHE WAS ABLE TO PUT THE CLUTCH IN AND STOP THE CAR AND TURN THE ENGINE OFF. THEN SHE HAD THE CAR TOWED TO THE NEAREST REPAIR SHOP. IT WAS DISCOVERED THAT A PLASTIC PART ON THE TIP OF THE THROTTLE CAM HAD BROKEN OFF AND AS A RESULT THE THROTTLE CABLING MECHANISM STUCK IN THE PARTIALLY "OPEN" POSITION. I HAD THE THROTTLE CAM REPLACED WITH AN ALL STAINLESS STEEL CAM WHICH CANNOT BREAK DOWN AS A RESULT OF HEAT, AS PLASTIC OR A SIMILAR PRODUCT CAN DO. I HAD OEM CAMS REPLACED IN BOTH S4'S. AUDI DEALER WAS NOTIFIED OF THE PROBLEM IN OCTOBER 2007. I HAVE RECOMMENDED TO AUDI THAT ALL 1992-1997 S4 AND S6 MODELS BE RECALLED AND THAT ALL THROTTLE CAMS BE REPLACED WITH AN ALL STAINLESS STEEL CAM (FOR EXAMPLE, ONE FABRICATED BY 034 MOTORSPORT IN FREMONT, CA.) AT LEAST ONE OTHER INSTANCE OF UNINTENDED ACCELERATION, DUE TO FAILURE OF THE OEM THROTTLE CAM, HAS BEEN REPORTED ON THE "WEB" -- IN FACT THAT REPORT LED ME TO 034 MOTORSPORT'S SOLUTION. I KNOW I NEVER RECEIVED, FROM AUDI, A NOTICE OF THIS POTENTIAL PROBLEM. DATE SHOWN BELOW IS APPROXIMATE. I WOULD HAVE TO FIND THE TOWING BILL TO BE PRECISE. *TR

I RUN A SMALL REPAIR SHOP AND HAVE SEEN A NUMBER OF AUDI VEHICLES FROM 1986 TO 1998 WHICH HAVE STEEL GASOLINE LINES THAT COLLECT ROAD SALT AND RUST IN THE RUBBER SUPPORT GROMMETS ATTACHED TO THE CHASSIS. THE RUST CAUSES A PINHOLE LEAK WHICH THEN BEGINS TO SPRAY GASOLINE ON THE EXHAUST SYSTEM. I HAVE SEEN 5 OR 6 VEHICLES LIKE THIS IN THE PAST 5 YEARS AND SAW ANOTHER ONE LAST WEEK. *TR

I HAD PREVIOUSLY CONTACTED NHSTA REGARDING FUEL LINE LEAKS IN THE ENGINE COMPARTMENT OF THE EALRY S4 AND S6 MODELS. THIS RESULTED IN THE "KY" RECALL CAMPAIGN. MORE RECENTLY, SOME OWNERS HAVE BEEN DISCOVERING LEAKS IN THE FUEL LINES GOING FROM THE REAR OF THE CAR TO THE FRONT. THESE LEAKS OCCUR AT THE POINT WHERE THE FUEL LINE GOES THROUGH RUBBER ISOLATION/MOUNTING BLOCKS. MOISTURE ACCUMULATES AT THESE POINTS AND CORRODES THE FUEL LINE RESULTING IN LEAKS. I DISCOVERED THIS ON MY OWN CAR IN EARLY 2002 AND I KEEP HEARING FROM MORE AND MORE PEOPLE FINDING THE SAME THING. THESE CARS HAVE BEEN EXTREMELY GOOD IN OTHER AREAS BUT THE FUEL SYSTEM PLUMING LEAVES MUCH TO BE DESIRED. DT

They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.

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.
