Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 Q7.

The 2021 Audi Q7 requires 8.0 quarts of 0W-20 oil, establishing its mechanical baseline within a model complaint history tracked from 2007 to 2026. Records for this specific year document 67 total owner complaints and 9 recalls, with the electrical system designated as the top complaint area.

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 2021 Audi Q7 represents a notable shift in the generation’s federal record, particularly in recalls, which spiked to nine—nearly double the five issued in 2020 and the highest since the 2017 model year’s seven. Complaints also rose to 67, more than doubling the 25 reported in 2020 but still below the 2017 peak of 316, suggesting a mid-cycle correction rather than a systemic issue. The data doesn’t specify root causes for the complaints, but the top areas—electrical system (17) and engine (6)—align with broader trends seen in prior years, though without the extreme outliers of earlier generations. Compared to the 2020 model’s quieter record and the partial 2024 data (just one complaint), the 2021’s figures imply Audi addressed latent concerns proactively, likely through recalls. With no fire-related complaints and only three crash-related reports, the 2021 sits in a relatively stable phase of its lifecycle. **This makes it a reasonable used buy, provided all recall work has been completed.**
