Audi S4 reliability by year
Each year is complaints filed in that year’s first 3 years on the road, divided by however many of those years have passed. A model year younger than 3 years is too early to compare, so it is left out of the years named as having the fewest or the most complaints. Recalls are a separate count. The numbers are for the US-market Audi S4. How we count.
