Recalls and problems owners report

NHTSA lists four recall campaigns for the 2018 A4. 19V547000 covers oxidation on the Passenger Occupant Detection System cable that may make the software misdiagnose a malfunction and disable the passenger air bag, and 21V874000 covers a seat heater cable contact fault that can do the same. 17V675000 covers aluminum door trim around the speakers that can come loose and leave sharp edges, and 18V836000 covers a passenger air bag module mounting screw that may not be tightened enough, which affects the A4 Allroad.

Owners have filed 51 complaints with NHTSA: unknown or other with 20, electrical system with 19, structure and air bags with 7 each, and engine and fuel and propulsion system with 6 each. Kelley Blue Book (opens in a new tab) keeps a common-problems page for the year, and Consumer Reports (opens in a new tab) rates the 2018 A4 less reliable than other cars from the same model year.
