Affected 2019–2023 A8/A8L models with the 48V mild-hybrid system can experience an internal short circuit in the lithium-ion auxiliary battery, causing a sudden electrical system malfunction warning, loss of power steering, engine stall, and in rare cases smoke or fire. NHTSA recall 23V802 covers this defect. Repairs under recall are free; outside the recall, replacing the battery typically costs around $5,250 including parts and labor.
Affected 2020–2022 A8/A8L models with 3.0T or 4.0T engines can have a low-pressure fuel pump impeller that deforms, causing intermittent engine sputtering, sudden power loss, and potential engine stall while driving. NHTSA recall 22V183 addresses this defect. Typical replacement cost for the fuel pump is around $1,450 including parts and labor.
Affected 2019–2022 A8/A8L models with the 48V mild-hybrid system can have a belt-driven starter generator (BSG) failure that drains the 12V battery, triggers start/stop system malfunction or electrical system shut-off messages, and prevents the engine from cranking. This is a known weakness documented in TSB 01-22-34. Replacing the BSG and 12V battery typically costs around $4,350 including labor.
Affected 2019–2026 A8/A8L models with adaptive air suspension can develop air strut leaks and compressor failure, leading to an air suspension level too low warning, uneven ride height, visible sag, and a compressor that runs constantly or fails from thermal overload. Driving on a failed strut can damage the tire and fender liner. Replacing one air strut plus the compressor typically costs around $3,650 including parts and labor.
Affected 2019–2023 A8/A8L models with the dual-screen MMI can have the upper 10.1-inch touchscreen lose response, go black, or show burn-in within the first two years, disabling climate controls, navigation, and phone functions. Audi TSB 91-23-10 documents the issue. Replacing the MMI display module typically costs around $2,950 including programming and labor.
