Does the 2021 Audi Q5 have engine problems?

Owner complaints say yes, as a model-year pattern. 41 of 103 relevant complaints filed with NHTSA about the 2021 Audi Q5 concern the engine, transmission or fuel system (40%), and the largest group is filed under engine (22). For comparison, the 2020 scores 31% and the 2022 scores 35%. On a test drive, check for stalling, loss of power, rough idle, oil consumption or a check-engine light. This describes the model year, not any one car: a well-maintained or already-repaired example can be fine, and a clean model year can still have a bad car in it.

Manufacturers fix things mid-generation. A bad year next to a clean one is common; the fix usually arrived in between.

The percentage is each model year's drivetrain complaint share. No elevated signal describes the model year, not any one car; a well-kept example of a flagged model can still be the right buy, and any of these still needs an inspection.

Should I buy a 2021 Audi Q5?

That depends on the car in front of you, not just the model year. The 2021 Audi Q5 has an elevated engine complaint pattern, so treat it as a car that needs proof: service records showing engine work, a cold-start test drive, and an independent pre-purchase inspection focused on the engine. A well-kept or already-repaired example can be a fine car; an unknown one is a gamble.
