The 2005 Audi S4 page works best as a research starting point. Complaint totals show how much owner-reported activity exists, while recalls and investigations help show whether any of that activity turned into formal safety action.
Because this is a newer-era vehicle page, it usually helps to compare this year against nearby model years before deciding whether a complaint pattern looks isolated or persistent. On this page, the most prominent complaint area is exterior lighting with 29 reported complaints.
This page combines three types of NHTSA data: recall campaigns (official manufacturer or government actions), owner complaints (unverified consumer reports), and crash test ratings (where available). A vehicle with many complaints is not necessarily less reliable — complaint volume correlates with sales volume and vehicle age. Recalls indicate identified defects, not overall quality. To compare this model year with others, use the year navigation in the sidebar or return to the model overview page.
If you are researching a used vehicle, start with the complaint categories, compare them against the recall list, and then check nearby model years to see whether the same issue profile repeats. That usually produces a better buying or research signal than treating the raw complaint total as a standalone safety ranking.
