The 2003 Audi A6 has 3 recalls, the most serious involving fuel system risks: a worn fuel pump that can cut power to the engine and stall the vehicle in traffic, and a cracked fuel tank vent valve nipple on 4.2L models that can leak fuel and start a fire.
The fuel pump issue can cause the engine to cut out without warning while driving, leaving the vehicle without power in situations where loss of momentum creates a crash risk. The fuel tank vent valve concern is specific to vehicles with the 4.2L engine, where a nipple on the rollover valve can crack and allow fuel to escape near potential ignition sources. On the safety equipment side, certain vehicles equipped with a three-spoke sport steering wheel may have a driver's airbag igniter that was not properly seated during assembly, meaning the airbag may not deploy in a crash.
