Audi A4 Reliability Rankings: Years to Avoid and Best Years to Buy

NHTSA data as of Oct 15, 2026Published Oct 19, 2026

According to our reliability score system, the best Audi A4 years to buy are the 2011, 2012, 2015 to 2019 and 2021. The 2019 scores highest, at 87 out of 100.

No A4 year rates Avoid, but the 2000, 2003 and 2020 need a careful look. Owners of the 2000 most often report the ABS, mostly warning lights on the dash. On the 2003, the main complaint is the fuel pump, mostly stalling.

If you want a newer A4, look at the 2017 to 2019 and 2021 to 2023, which rate Good or Excellent. Be careful with the 2020. The 2024 has too little data to score. The 2025 is too new for a final score.

For an older A4, made before 2017, the 2007 to 2016 rate Good or Excellent. The 2000 to 2006 are the ones to check closely.

Vs average: how this year's complaint rate compares with the average car of the same age. 1× is average, 2× is twice as many. Per 10k cars: complaints so far for every 10,000 cars Audi made for the U.S. that model year. The complaint count also includes owners who wrote in only about a recall notice, with no problem to report. The score leaves those out. Generations follow Audi's own model history.

How We Score Each Model Year

1

Count What Owners Report

Every complaint filed with NHTSA for the model year, plus its recalls. Recall-notice filings with no fault are left out.

2

Adjust for How Many Were Made

A popular car gets more complaints just because there are more of them. We divide by the number Audi made for that model year and compare with the average car of the same age.

3

Turn It Into a Score

70 is average. Twice the average rate of complaints costs 10 points, half the rate adds 10. Serious problems count more than everyday ones.
