All data on this page comes from the National Highway Traffic Safety Administration (NHTSA). Complaints are filed by Audi S4 owners directly with NHTSA. Recalls are issued when a safety-related defect is identified.
Higher complaint volumes do not necessarily mean a model is unsafe — popular, high-volume models naturally accumulate more reports over time. The best use of this data is to compare year-to-year trends and identify specific recurring issues.
