2021 Audi SQ5 Sportback

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 SQ5 Sportback.

Transmission Automatic (S8)

The 2021 Audi SQ5 Sportback is a performance-oriented crossover that rides on Audi’s MLB platform and is powered by a turbocharged engine requiring 7.7 quarts of 0W-20 oil, paired with an eight-speed automatic transmission and delivering EPA fuel economy ratings of 18 mpg city, 24 mpg highway, and 20 mpg combined. This model year carries forward the Sportback’s sloping roofline and aggressive styling while offering the brand’s signature Quattro all-wheel drive. In terms of reliability, the 2021 SQ5 Sportback recorded five recalls and accumulated 11 owner complaints primarily centered on the powertrain, electrical system, and engine—issues that place it within a broader pattern of early-stage teething problems common to many new vehicle introductions, suggesting prospective buyers should verify that all recall work has been completed during pre-purchase inspections.

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 SQ5 Sportback shows 11 complaints, 5 recalls, 0 investigations, and 972 TSBs in the federal record. Because the supplied year-by-year data begins with 2021, no prior-model comparison is possible; against the only later year shown, 2025, every metric is higher in 2021, with complaints at 11 versus 0, recalls at 5 versus 1, and TSBs at 972 versus 666. The top complaint categories are fragmented, each registering only a single report across power train, electrical, engine, and engine-cooling areas, and the data records zero crash and zero fire complaints. This places 2021 at the higher-activity end of the limited two-point arc, consistent with the earliest year in the supplied record accumulating field reports and service bulletins. While the 5 recalls warrant a careful recall-history check, the absence of investigations, fires, and crashes keeps the safety profile unremarkable in the federal data. For a used-car buyer, 2021 is a usable but not standout choice: verify all recalls are completed, and if possible, favor a later year in the generation where the federal record shows lower complaint and recall activity.
