2006 AUDI A3 Recalls — Canada & USA

Recalls 4 and 5 describe the same underlying defect (curtain airbag inflator leak) filed in multiple jurisdictions. Recalls 1 and 2 both involve the driver's frontal airbag inflator but describe distinct failure modes (rupture vs. degraded propellant causing excessive force). I'll treat Recalls 4/5 as one issue and keep Recalls 1 and 2 as separate issues since the physical failure is different in each case. The 2006 Audi A3 has 5 recalls, the most serious being a driver's frontal airbag inflator that can rupture on deployment, sending metal fragments into the cabin and potentially causing serious injury. A related airbag concern affects the same driver's frontal airbag: long-term exposure to heat and humidity can degrade the inflator's propellant, causing the bag to deploy with more force than intended. The side curtain airbags also have a concern of their own, where the inflator module can leak and leave the curtain bag without enough pressure to fully inflate in a crash. On the fuel system side, this recall only affects Quattro models: a weak spring in the fuel tank ventilation valve can allow liquid fuel to push past the valve and saturate the carbon canister in the evaporative emissions system, which can create a fire risk.
