2015 Audi A4 problems: engine and transmission complaints and recalls
70% of relevant owner complaints filed with NHTSA on the 2015 Audi A4 are about the engine, transmission or fuel system. Well over half of everything owners reported is the drivetrain. That is a severe model-level pattern; every model year we track at this level has a documented failure behind it.
Worse than 92% of the 1,789 model years we track (2010–2023).
Excludes 7 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 59%).

Check a VINDoes the 2015 Audi A4 have engine problems?
Owner complaints say yes, heavily, as a model-year pattern. 26 of 37 relevant complaints filed with NHTSA about the 2015 Audi A4 concern the engine, transmission or fuel system (70%), and the largest group is filed under engine (16). For comparison, the 2014 scores 51% and the 2016 scores 57%. 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.

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.

Before you buy a 2015 Audi A4
- Ask the seller whether the engine has ever been repaired or replaced, and whether the car has shown stalling, loss of power, rough idle, oil consumption or a check-engine light.
- Drive it from a cold start and long enough to warm up. Many engine faults hide once the car is warm.
- Get an independent pre-purchase inspection from a mechanic you choose, and tell them to focus on the engine.
- Ask for service records. A engine already replaced under warranty is a different car from one that was not.

That depends on the car in front of you, not just the model year.

A well-kept or already-repaired example can be a fine car; an unknown one is a gamble.
