2018 Audi s5 sportback common problems

The most-reported problem areas across all 26 owner complaints filed with NHTSA — and what to check before you buy.

Engine
Listen for knocks or ticking, check for leaks and blue/white exhaust smoke, and make sure it doesn't overheat. No check-engine light should be on.
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.
Visibility/wiper
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
Seat Belts
Check that every belt latches, retracts and locks under a sharp tug, and that none are frayed.
Parking Brake
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
Power Train
Drive through every gear: watch for slipping, hard or delayed shifts, and shudder. Check for transmission/driveline leaks and noises.
