2015 Audi Q5/SQ5

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 Q5/SQ5.

Body SUV

The 2015 Audi Q5/SQ5 is an SUV whose routine engine-oil service is specified at 5.0 quarts of 5W-40, 5W-30, or 0W-40 viscosity oil. Its reliability profile shows 97 owner complaints, with engine issues leading the categories, alongside six recalls. That pattern makes the 2015 model year a focal point for engine-related concerns in the Q5/SQ5 history and signals that researchers should weigh owner-reported engine problems and recall coverage carefully.

Reliability & federal safety record

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

Owner complaints about the 2015 Audi Q5/SQ5 lead in one area — the engine, 24 of 97 reports (25%), well ahead of the next concern. None of this vehicle's 6 recall campaigns target the engine, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 3 of the reports describe a crash and 1 a fire — a small share of the total, but worth weighing against the engine pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
