Audi A4

The Audi A4 is a luxury compact sedan built for five generations from 1994 to 2025, with the Audi A5 listed as its successor. Among the years on this site, 2021 has the most recalls (4), 2020 has the most complaints (127) with 3 recalls, and 2015, 2016, 2024, 2025 and 2026 show no federal recalls.

What the Audi A4 is and who buys it

Wikipedia (opens in a new tab) describes the A4 as a line of luxury compact executive cars produced from 1994 to 2025 by Audi, a subsidiary of the Volkswagen Group, built in five generations from the B5 to the B9, with the Audi A5 (B10) as successor. Latterly (opens in a new tab) says the A4 targets buyers who want luxury and sophistication in a practical package, including professionals, commuters and small families, and that used pricing can be attractive relative to German rivals.

The generations that matter for used buyers

The model years on this site sit in the B9 generation and its facelift, which Wikipedia's photo captions call the B9.5. Auto Broker Magic (opens in a new tab) says the B9 largely avoided the serious teething problems that affected some earlier Audi models, and calls it lighter, quieter, more fuel efficient, more technologically advanced and considerably more reliable than the early B8 models that preceded it. See the 2017 A4 for the first B9 model year on this site and the 2021 A4 for a facelifted car.

Best and worst A4 model years

Federal counts are low compared with mass-market models. The 2015 and 2016 have no recalls and 44 and 26 complaints. The 2017 has 1 recall for seats and 81 complaints, the 2018 has 1 and 42, and the 2019 has 1 recall and 5 complaints. The 2020 has 3 recalls covering tires, suspension and seats, and 127 complaints, the most of any year, and the 2021 has 4 recalls, the most recalls, covering seat belts, tires, suspension and the backup camera, with 11 complaints. The 2022 has 3 recalls including the backup camera and engine cooling. The 2024, 2025 and 2026 show no recalls and almost no complaints, which reflects how little time they have had on the road.

Reliability guides look further back than this generation. REREV (opens in a new tab) says certain model years have been deemed less reliable than others by drivers and publishes a best and worst list, and Car Smite (opens in a new tab) says the 2008 model year stood out for improved reliability and refinement over the earlier years of its generation.

Strengths and weaknesses

The strengths are the refinement of the B9 and the value of a used example against German rivals. The weaknesses in federal data are recurring seat and tire campaigns across 2017 to 2021 and the backup camera recalls on the 2021 and 2022. Latterly names the Acura TLX as a rival that matches the A4 on size while often undercutting rivals on price for features.

Method: recall counts and their affected components come from the NHTSA Office of Defects Investigation: Recalls API, queried by exact make, model and model year. Complaint counts come from the NHTSA Office of Defects Investigation: Complaints API, same query pattern. Data pulled 2026-09-04.

Known gap: the NHTSA complaints API did not return data for Audi A4 model year 2022 when queried for this page: the request itself failed upstream, not returning a genuine zero. Those years are marked "not available" above instead of shown as clean; recall counts for those years are unaffected and come from the separate recalls API, which returned data for every year listed.

Check open recalls by VIN for one particular vehicle.

Q01Is there a best year to buy a Audi A4?

Federal recall records don't single out a best Audi A4 model year: recall counts across the 6 published model years checked here stay within a normal range of this nameplate's own average (about 2.2 recalls per year), with no year standing out as notably higher or lower. Recall count is one input, not a purchase verdict. It says nothing about a specific vehicle's price, mileage, accident history or maintenance record.

Q02What are common recall-related problems on the Audi A4 by model year?

2022: backup camera, engine cooling, equipment. 2021: seat belts, tires, suspension, backup camera. 2020: tires, suspension, seats. 2019: seats. 2018: seats. 2017: seats.

Q03Why do some Audi A4 model years show "not available" for complaints?

The NHTSA complaints API did not return data for Audi A4 model year 2022 when queried for this page: the request itself failed upstream instead of the count genuinely being zero. Recall counts for those years are unaffected; they come from a separate NHTSA endpoint that returned data for every year listed.
