Complaints owners filed with NHTSA naming each system, per model year; a bold count links the year’s own page on that system. Counts scale with sales and with time on the road; nothing here is a rate, and NHTSA’s headings are coarse (“Power Train” is the transmission and the driveline).
Common questions
Source: NHTSA complaint databaseWhich Audi A6 system draws the most complaints?
Electrical: 140 complaints across 12 model years, 50% of everything owners filed about the Audi A6. A count, not a rate — it says nothing about how many were sold.
Which Audi A6 year has the most complaints?
2019 (114), 2016 (51), 2020 (33). Older years have had longer to collect them; the year pages show each year's share by system.
