NHTSA lists 4 safety recalls and 42 owner complaints for the 2011 Audi A3. Most complaints involve air bags (20) and fuel/propulsion system (6). The EPA rates it 24–32 mpg combined.
Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2012-2015 Passat, 2011-2014 Golf A6, and 2011-2013 Audi A3 diesel vehicles, thought to have been previously repaired under one of the Takata air bag recalls. The driver's side air bag inflator may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, high temperatures, and high temperature cycling.
Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2006-2013 Audi A3, 2007-2009 A4 Cabriolet and S4 Cabriolet, 2008 RS4 Cabriolet, 2009-2012 Q5, and 2010-2012 Audi A5 Cabriolet and S5 Cabriolet vehicles. Upon deployment of the driver's frontal air bag, excessive internal pressure may cause the inflator to explode.
Volkswagen Group of America, Inc. (Volkswagen) is recalling certain model year 2006 Volkswagen Passat sedans and wagons, 2005-2013 Audi A3, and 2006-2009 Audi A4 Cabriolet vehicles. Upon deployment of the driver's frontal air bag, excessive internal pressure may cause the inflator to rupture.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“Airbag warning light came on. Dealer said passenger seat occupancy sensor must be replaced, at cost of $1500-3000 since it's 5 months past my warranty. Numerous Audi models from 2012 onward have a recall for this sensor, but not my 2011 model (yet). Other automakers have extended their warranty for this safety-critical part -- BMW to 15 years, for example. Technicians could not tell me if the sensor error means all airbags are disabled, passenger airbag only is disabled, or passenger airbag is always-on (dangerous for children).”
“MY SON WAS DRIVING MY 2011 AUDI A3 TDI TO THE GYM AT NIGHT WHEN HE CALLED ME THE CAR WOULD NOT ACCELERATE AND HAD A WARNING LIGHT COME ON. I TOLD HIM TO GOOGLE IT AND HE FOUND OUT IT WAS A GLOW PLUG INDICATOR. I TOLD HIM TO CONTINUE DRIVING IT IN THE LIMP MODE. THE CAR DIED WHILE MOVING AND MY SON WAS ABLE TO COAST INTO A PARKING LOT. THIS COULD OF BEEN A DIFFERENT STORY ON A BUSY INTERSTATE. I HAD TO PICK HIM UP AND HAD THE CAR TOWED IN THE MORNING. TO FIND OUT THIS CAR IS NOTORIOUS FOR CATASTROPHIC HIGH PRESSURE FUEL PUMP FAILURE AND THAT IS EXACTLY WHAT HAPPENED. WHEN I SAY CATASTROPHIC, METAL IS SHREDDED AND GOES INTO THE INJECTORS AND CONTAMINATES EVERYTHING THAT CARRIES FUEL. IT IS ABOUT A 7K TO 8K REPAIR. I HAVE USED NOTHING BUT LOW SULFUR DIESEL. IT'S RIDICULOUS A RECALL HASN'T BEEN ISSUED TO PREVENT THIS ISSUE. SINCE THIS HAPPENED I HAVE FOUND COMPLAINTS SCATTERED THROUGHOUT THE INTERNET.”
“COOLANT PUMP- AUDI ACTION CODE-19L2-"THE COOLANT PUMP MAY DEVELOP A SMALL LEAK OVER TIME." MY AUDI SUFFERED A COOLANT LEAK AND HAD TO FIX FOR $1100 IN DIAGNOSIS/REPAIRS. I REPAIRED IT ON MY OWN AND LATER I LEARNED THAT THERE WAS A RECALL FROM AUDI. I NEED TO GET MY REIMBURSEMENT FOR THE MONEY I PUT UP TO FIX COOLANT LEAK.”
