Volkswagen Group of America, Inc. (Audi) is recalling certain 2019-2026 vehicles. Please see the recall report for a complete list of models. A software error may prevent the rearview camera image from displaying as intended. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“My Audi RS6 has experienced a recurring central locking/door latch malfunction. The vehicle displays a “Central Locking System Malfunction” warning and the affected door does not operate normally. This appears to be a known issue affecting the C8 Audi platform. Audi has issued a Technical Service Bulletin addressing front and rear door-lock failures on the RS6 and other related models. Audi’s own bulletin describes conditions including doors that cannot be opened from the outside or inside, central-locking/exit-warning messages, and situations where a vehicle is locked but a door can still be opened. The bulletin also identifies faults involving the central-locking mechanism and states that the door-lock manufacturing process was optimized. I am concerned this represents a safety defect rather than simply a convenience issue. A malfunctioning door-lock/latch mechanism may prevent an occupant from opening a door normally during an emergency, or may prevent a door from remaining properly secured when the vehicle is supposed to be locked. This could be particularly dangerous following a collision, fire, or other situation requiring rapid vehicle evacuation.…”
“My Audi RS6 has experienced a failure involving the engine cooling system/water pump that requires repair. This appears to be a recurring issue among C8 RS6 owners. Other owners have reported water-pump failures, coolant loss, overheating, drivetrain malfunction warnings, turbo underboost faults, and vehicles entering reduced-power or limp mode. Audi has also issued technical service information addressing coolant-pump leakage and related cooling-system problems. I am asking NHTSA to investigate this issue because the potential safety consequences appear to extend beyond an expensive mechanical repair. If the cooling-system failure occurs while driving, the vehicle may overheat, display urgent coolant warnings, enter reduced-power/limp mode, or require the driver to immediately pull off the road. A sudden or significant reduction in available engine power can be dangerous, particularly while merging onto a freeway, passing, crossing traffic, or driving at highway speeds. Likewise, an overheating vehicle may force the driver to stop unexpectedly in an unsafe location. There appear to be numerous RS6 owners reporting similar water-pump and cooling-system…”
