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 2002 Audi A4/A4 Quattro/S4/Avant dominate in one area — the electrical system, 65 of 189 reports (34%), well ahead of the next concern. None of this vehicle's 2 recall campaigns target the electrical system, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 13 of the reports describe a crash and 6 a fire — a small share of the total, but worth weighing against the electrical system 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.
