What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2010 Audi S4, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

MY AUDI S4 2010 IS HAVING A MECHATRONIC ISSUE. WHILE DRIVING MY VEHICLE DOWN THE STREET IT DROPPED A GEAR AND A ERROR MESSAGE POPPED UP STATING GEARBOX MALFUNCTION: NO REVERSE GEAR. MY VEHICLE WAS THEN UNABLE TO REVERSE AND ALSO KEPT DROPPING AND JUMPING TO DIFFERENT GEARS. IT MADE A VERY UNSAFE AND SCARY DRIVE,I HELD UP ALOT OF TRAFFIC TRYING TO DRIVE BACK TO MY HOUSE. TO GET A NEW MECHATRONIC COST BETWENN 3-8 THOUSAND DOLLARS. ALSO THERE ARE THOUSANDS OF AUDI OWNERS ON THE WEB WHO ARE HAVING THE SAME ISSUE. I THINK AUDI SHOULD RECALL THIS PART THAT IS CAUSING SO MANY ISSUES WITH THE VEHICLE.
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.

MY CAR FLASHED GEARBOX MALFUNCTION WHILE DRIVING DOWN INTERSTATE I-264 IN LOUISVILLE KY. CAR SEAMED FINE FOR ABOUT 2 MILES AND THEN SUDDENLY WENT LIMP AND I HAD NO GEARS. HAD TO HIT FLASHERS AND COAST INTO MEDIAN. WAS ALMOST HIT BY SEMI TRUCK. REPAIR SHOP COULD NOT FIND ANYTHING WRONG. HAPPENED AGAIN 1 DAY AFTER GETTING IT BACK FROM SHOP. TAKING IT TO AUDI NOW. I HAVE READ THAT THIS IS A COMMON PROBLEM.
IT HAPPENED AGAIN TODAY DRIVING DOWN THE HIGHWAY GOING UP TO SPEED, AT ABOUT 50 MPH I GOT A "GEARBOX MALFUNCTION" ERROR MESSAGE IN THE CLUSTER AND IT WOULD NOT LET ME ACCELERATE ANYMORE, IT WAS LIKE THE CAR WAS IN NEUTRAL AND PRESSING THE ACCELERATOR PEDAL WOULD JUST REV UP THE ENGINE. THE MECHATRONICS UNIT ON THESE VEHICLES ARE FAULTY, I KNOW 2 OTHER S4 OWNERS WITH THE YEARS OF 2011 AND 2012 WHO ALSO HAD THEIR MECHATRONICS FAIL ON THEIR S4. ALONG WITH THE GEARBOX MALFUNCTION ERROR ALSO COMES "PARKING BRAKE ERROR" WHO KNOWS WHAT IN THE WORLD CAN HAPPEN WHEN THAT MESSAGE COMES UP. IS IT GOING TO SUDDENLY APPLY THE ELECTRONIC PARKING BRAKE GOING 50-70 MPH DOWN THE HIGHWAY AND CAUSE A POSSIBILITY OF A VERY BAD ACCIDENT? THE REPAIR IS VERY PRICEY FOR THE MECHATRONIC UNIT THAT GOES BAD, IT IS NO COINCIDENCE MANY OF THESE S4 MODELS HAVE THESE GO BAD.

FOLLOW UP ON AUDI S4 2010: ELECTRONIC PARKING BRAKE DISENGAGED WHILE PARKED IN SLOPED PARKING LOT. CAR ROLLED BACK INTO ANOTHER PARKED VEHICLE CAUSING 1800 DOLLARS WORTH OF DAMAGE. CALLED THE AUDI DEALERSHIP ABOUT THIS ISSUE AND THEY CLAIM "THEY HAVE NEVER HEARD OF IT. " I DID SOME RESEARCH AND APPARENTLY THIS PROBLEM HAS BEEN REPORTED BY APPROXIMATELY 6 OTHER PEOPLE ON AUDI FORUMS SUCH AS AUDIFORUM.COM

GEARBOX MALFUNCTION AND TPMS MALFUNCTION WHILE DRIVING ON THE ROAD WITHIN THE CITY ABOUT 45MPH I FELT A SLIGHT JERK AND IMMEDIATELY FOLLOWING THE WARNINGS CAME ON IN THE DASHBOARD "TIRE PRESSURE! SYSTEM MALFUNCTION" & "GEARBOX MALFUNCTION: NO REVERSE GEAR (YOU CAN CONTINUE DRIVING)" THROTTLE RESPONSE WAS OFF AND FORCED ME TO IMMEDIATELY PULLER OVER! WHILE STOPPED I RE-STARTED THE VEHICLE AND THE WARNINGS WENT AWAY, I SAT THERE FOR A COUPLE MINUTES AND THEN CONTINUED DRIVING. FEW MILES DOWN THE ROAD THE VEHICLE JERKED AGAIN AND WARNINGS CAME BACK ON, I NEEDED TO GET TO WORK SO I CONTINUED DRIVING; THE CAR WOULD TAKE VERY LONG TO SHIFT GEARS AND IT WOULD JUMP FROM 1ST TO 3RD, FROM 3RD TO 5TH AND 5TH TO 7TH GEAR JERKING KIND OF VIOLENTLY EVERY-TIME AND THROTTLE RESPONSE BETWEEN SHIFTS WAS VERY LETHARGIC TO THE POINT THAT THE VEHICLE WOULD SLOW DOWN SEVERELY AND I FELT UNSAFE DUE TO CARS GETTING REALLY CLOSE TO MY REAR AND THEM HAVING TO SLOW DOWN DRASTICALLY WHILE THE CAR SHIFTED GEARS. DUE TO THE NUMBER OF COMPLAINTS I STRONGLY FEEL THAT AUDI SHOULD BE LIABLE AND HELD ACCOUNTABLE FOR ALL REPAIRS NECESSARY AND ACCIDENTS THAT THIS ISSUE CAN CAUSE. IF THIS ISSUE WOULD OF PRESENTED ITSELF WHILE TRAVELING AT 75MPH ON THE HIGHWAY I BELIEVE IT COULD OF BEEN A CASE OF LIFE & DEATH. AUDI IS PUTTING THE PEOPLE DRIVING THEIR VEHICLES AND OTHERS AROUND AT RISK BY NOT RECALLING AN UNIT OR UNITS KNOWN TO CAUSE PROBLEMS.

2010 AUDI S4 WATER PUMP FAILURE -- THIS COMPLAINT IS IDENTICAL TO THE PREVIOUS TWO COMPLAINTS SURROUNDING THIS MODEL'S WATER PUMP FAILURE. IT SHOULD BE NOTED THAT A NEAR FULL LOSS OF STEERING DIRECTLY RELATED TO THIS FAILURE OCCURRED AT THE SAME TIME. IN MY CASE THE CAR HAS BEEN REPAIRED, HOWEVER LIKE OTHERS WHO HAVE DETAILED THEIR EXPERIENCES, AUDI HAS NOT ACKNOWLEDGED THIS IS A SYSTEMIC ISSUE FOR THIS MODEL, NOR IS THE REPAIR SATISFACTORY AS THE DISTINCT ODOR OF G-12 (G-30 IN EUROPE) IS PRESENT. THOUGH THIS IS A SAFETY ISSUE FIRST, IT IS ALSO A CONSUMER PROTECTION MATTER AS THE BOTH THE DEALER AND AUDI OF AMERICA WHO I HAVE BEEN IN COMMUNICATIONS WITH HAS NOT BEEN CLEAR ABOUT THIS ISSUE. *TR
