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…

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 consequ…

Emerging complaint spikes

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.

Equal-age model-year comparison
