Back-Seat Spills Could Cut Engine Power

  • Audi is recalling 50,883 A6 and A7 cars because a port control module can unexpectedly shut down and interrupt engine power.
  • The problem appears to have been caused by fluid spilled in the car’s rear seat area.
  • Audi plans to install a protective covering over the affected area and will notify owners in January to bring their vehicles in for the fix.

Audi has announced the recall of more than 50,000 vehicles due to a risk that liquid spilled in the rear seat area could cause a port control module to shut down, which could unexpectedly reduce engine power. The automaker’s report submitted to the National Highway Traffic Safety Administration (NHTSA) states that the affected vehicles were manufactured without a protective cover over this module.

The recall includes the 2019–2022 A6 and A7; the 2020–2022 A6 Allroad, S6 and S7; and the 2021–2022 RS6 and RS7 (pictured above). The A6 makes up most (32,585) of the affected vehicles.

According to the report, the module is located under the rear center seat, and if water or other liquids get into that area, a short circuit can cause the port to shut down, putting the vehicle in limp-home mode. In this situation there will be warning messages. The vehicle will still be drivable and the brakes will work, but power will be reduced, the report explains. As of October, 46 cases had been reported in the US, but no injuries or accidents resulted, Audi said.

Owners will be notified by January 20, 2023 to bring their Audi in for a protective wrap to be installed. In the meantime, they can check the NHTSA recall website for information about the recall and to see if their vehicle is affected.
