Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2023 Audi A6 allroad sits in an interesting position within this generation's federal record: it falls between the early-year spike (2021 peaked at 24 complaints and 12 recalls) and the pronounced cooling-off seen from 2024 onward (0–2 complaints, 1 recall annually). Notably, 2023 itself does not appear in the year-by-year federal record, and the only target-year data available shows a single complaint categorized as "Unknown or Other," with zero crash or fire complaints — suggesting very low reported issue volume. The broader trend across the generation is one of early teething problems concentrated in 2020–2021, followed by a steady decline in both recalls and technical service bulletins (TSBs dropped from a peak of 1,311 in 2021 to 675 by 2024). The data does not specify any root cause for the lone 2023 complaint, and no recalls or investigations are recorded for that year. Taken together, the 2023 model year appears to land on the favorable side of the generation's maturity arc — past the early-year problem cluster but before any new-issue resurgence — making it a reasonable used-buy candidate, with the caveat that the thin federal record means you should rely heavily on a pre-purchase inspection and service history rather than complaint data alone.
