NHTSA lists 1 safety recall and 5 owner complaints for the 2018 Audi S3. Most complaints involve fuel/propulsion system (2) and power train (2). The EPA rates it 25 mpg combined, and NHTSA gives it 5 stars overall.
Volkswagen Group of America, Inc. (Audi) is recalling certain 2015-2020 Audi S3 Sedan, A3 Sedan, 2016-2018 A3 Etron, 2017-2020 RS3 Sedan, and 2015-2019 A3 Cabriolet vehicles. The passenger occupant detection system (PODS) may malfunction and switch off the passenger air bag even when the seat is occupied.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“Having the same issue as the NHTSA Part 573 Safety Recall Report, 24V-110. And, similar to NHTSA 16V647 associated with the Audi Safety Recall 20Y5 - Suction Pump. Apparently there is no recall for my S3, only the A3. Dealer has determined the suction pump and gas tank are faulty. (Inherit defect by manufacture?). Audi is not acknowledging any upcoming recall but may try to help through their assistance program.”
“The car was put in Drive "D". As I roll out into traffic and start to accelerate, the car "bang" out of gear like it's in neutral, the revs climb, but the car doesn't accelerate and the "D" display disappeared from the instrument panel. The gear selector display on the instrument panel is now blank (instead of "D" if it was in gear or "N" if it was out of gear). I have to pull to the side of the road and stop and the "D" reappeared and then all seems to be fine again. This has happened twice in the last two months. I had a local mechanic scan the vehicle for transmission fault, but found nothing was stored.”
“Audi will not fix the problem.”
