2018 Audi s5 common problems

Owners have filed 26 complaints with NHTSA. These are the most-reported areas in a sample of the most recent — 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.
Seat Belts
Check that every belt latches, retracts and locks under a sharp tug, and that none are frayed.
Seats
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
Parking Brake
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
Fuel/propulsion System
Check for fuel or battery warnings, hard starts and stalling. On a hybrid/EV, confirm charging and range behave normally.
