    Safety restraint issue

    SEATS

    Volkswagen Group of America, Inc. (Audi) is recalling certain 2017-2020 A4 Allroad, A4 Sedan, 2018-2019 RS5 Coupe, 2019 RS5 Sportback, 2018-2020 A5 Cabriolet, A5 Coupe, A5 Sportback, S4 Sedan, S5 Cabriolet, S5 Coupe, and Audi S5 Sportback vehicles. The cable connecting the seat heater to the Passenger Occupant Detection System (PODS) may have a contact fault, causing the software to misdiagnose a malfunction and disable the passenger air bag.

    Consequence

    A disabled passenger air bag increases the risk of injury in the event of a crash.

    Remedy

    Dealers will replace the connecting cable and either the heating mat or entire seat cover, free of charge. Owner notification letters were mailed January 7, 2022. Owners may contact Audi customer service at 1-800-253-2834. Audi's number for this recall is 74E3. This recall is an expansion of Recall 19V-547 (74D9). Vehicles previously repaired under 19V-547 will need to return for the new remedy.

What the ratings mean

NHTSA gives the 2018 Audi A4 5 out of 5 stars overall. NHTSA does not publish enough comparable results for this class and year to rank it against peers.

NHTSA published results for every NCAP test in this program, so the overall star rating rests on a complete set of crash and rollover results.

NHTSA's dynamic test put this vehicle's rollover probability at 9.9% in a single-vehicle crash — the figure behind the rollover star rating, published here because the star alone hides how wide each band is.
