Recalls 1 and 3 describe the same underlying defect, so this is effectively two distinct issues.
The 2004 Audi A8 has 3 recalls, the most serious being a driver's frontal airbag that may not unfold or inflate correctly in a crash, leaving the driver without that protection when it matters most.
The steering system carries a separate concern: if the vehicle's electrical system fails and the driver uses the optional override device to remove the ignition key while the transmission is not in Park, the steering wheel does not lock as required. A car left in this state could roll away without the wheel locking to signal or limit movement. This recall applies specifically to A8L models rather than the full A8 lineup.
