Audi S6 Recalls

The Audi S6 has 22 recalls spanning 1992 through 2025, with the most serious recent issue affecting 2020–2021 models where a broken rear axle lock nut can misalign the rear wheels and cause sudden loss of control.

The 2020–2022 model years carry several other significant concerns. Liquid spilled in the rear seat on 2020–2022 vehicles can reach the gateway control module and cause it to shut down, cutting engine power without warning while driving. The passenger airbag on 2020–2021 models may have an incorrectly manufactured score line, meaning it can fail to deploy properly in a crash or eject plastic debris into the cabin. On those same years, the fuel level sender can stick and show an inaccurate reading, potentially causing the engine to stall from fuel starvation. The rearview camera on 2020–2025 models can fail to display the image behind the vehicle due to a software error. A separate software fault on 2021 models can cause the instrument panel to go blank, taking the speedometer and warning lights with it, and another software issue on 2022 models can also disable the rearview camera display. The 2021 model year additionally has a rear seatbelt retractor that may not properly secure a child restraint in a crash, and a brake fluid reservoir cap that may be incorrectly labeled, leading to the wrong fluid being used and reduced braking performance. Rear axle misalignment on 2020–2021 vehicles can also cause uneven or premature tire wear.

Going back to the 2013–2018 range, the passenger seat occupant detection mat can wear or stress over time on 2013–2018 models, causing the sensor module to malfunction and potentially preventing the front passenger airbag from deploying in a crash. The turbocharger oil supply strainer on 2013–2017 models can become blocked, starving the bearings of lubrication; a broken shaft or turbine contact with the housing can stall the engine while driving. Fuel line issues on 2013–2014 models with 4.0L engines and a separate fuel line defect on 2013 models both create the risk of fuel leaking near ignition sources and starting a fire.

The 2007–2011 model years are affected by Takata airbag inflator recalls, where the passenger frontal airbag inflator can rupture or explode and send metal fragments into the cabin, with the risk of serious injury or death. The 2009 model year has an additional airbag propellant degradation issue where high humidity and temperature cycling can cause the passenger airbag to deploy with excessive force. The 2009 model is also covered under the broader 2007–2009 inflator recall.

Earlier production has two separate recalls on 1992 and 1996 models where a fuel feed line shrinks from turbocharger heat, loosening a clamp near the turbocharger and allowing fuel to seep out. The 1995 model year has a recall where static electricity discharge under low-humidity conditions can trigger the driver's airbag when the driver touches certain areas of the steering wheel while entering or exiting the vehicle.
