Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 A4 allroad.
The 2015 Audi A4 allroad is a passenger car with a 5.0-quart oil capacity accepting 5W-40, 5W-30, or 0W-40 viscosity, paired with an automatic AV-S8 transmission and EPA ratings of 24 city, 31 highway, and 26 combined mpg. Its reliability record shows 44 total owner complaints, with the engine as the top complaint area, and 4 recalls. This model year sits before the 2018–2024 complaint history, where the model saw a high of 154 complaints in 2020 and a low of 1 in 2021, indicating that the 2015’s reliability profile is distinct from the wider variability seen in later years.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The provided federal record does not include 2015 or any prior model years, so the 2015 Audi A4 allroad sits before the earliest available arc, which spans 2018 through 2024. Across that recorded span, the trend shows low complaint and recall activity in 2018–2019, a pronounced spike in 2020 with 154 complaints and 3 recalls, and a subsequent return to minimal complaints from 2021 onward. For 2015 itself, the data shows 11 engine complaints, 5 powertrain complaints, and 3 electrical system complaints, alongside 4 crash-related complaints but zero fire complaints. Because 2015 predates the 2020 surge, it is not exposed to the peak complaint volume seen in later years, though the isolated 2015 data still shows a concentrated cluster of engine and powertrain complaints. The data does not specify root causes for the 2015 issues, so buyers should verify whether those engine and crash complaints reflect isolated incidents or systemic defects. Overall, 2015 appears to be a relatively moderate-risk year compared with the 2020 peak, but prospective buyers should prioritize a pre-purchase inspection focused on engine and powertrain performance given the documented complaint concentration in those areas.
