NHTSA lists 1 safety recall and 2 owner complaints for the 2009 Audi S8. Most complaints involve visibility/wiper (1) and visibility (1). The EPA rates it 15 mpg combined.
Volkswagen Group of America, Inc. (Volkswagen) is recalling certain model year 2007-2009 Audi A8 and S8 vehicles. The sunroof glass on the affected vehicles may not be properly secured to the sunroof frame. As a result, the sunroof glass may detach from the car while driving.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“While driving on the highway my sunroof glass detached from the frame and flipped over to the back. It was still being held by about 5in of glue on the rear part of the frame and luckily it didn't depart the car which would have caused damage to cars behind me. This issue seems the same as NHTSA Recall No. / MFR Recall No. : 16V-415 / 60C3, however my VIN is not part of it. I'm reporting this because there might be other cars out there affected by this recall, which is a road hazard to other people and vehicles that are traveling behind this car.”
