2018 Audi s3 common problems

The most-reported problem areas across all 5 owner complaints filed with NHTSA — and what to check before you buy.

Fuel/propulsion System
Check for fuel or battery warnings, hard starts and stalling. On a hybrid/EV, confirm charging and range behave normally.
Power Train
Drive through every gear: watch for slipping, hard or delayed shifts, and shudder. Check for transmission/driveline leaks and noises.
Air Bags
Confirm the airbag light turns on then off at startup — if it stays lit there's a fault (costly, and a safety risk). Check for signs of prior deployment.

Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
