What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2009 Audi S8, 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.

From owner reports, verbatim
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.

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.
