Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Owner complaints about the 2009 Audi A8/S8/A8 lead in one area — the visibility, 1 of 5 reports (20%), well ahead of the next concern. That matters, because the visibility are also the target of recall 16V-415 on this vehicle — so the single most useful check before buying or servicing one is confirming it was actually performed. 1 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the visibility pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
