Audi A4 Recall 21V470: Driver Airbag May Not Protect in a Crash

NHTSA campaign 21V470, reported June 23, 2021, 62,812 vehicles potentially affected.

What this recall means for you

Certain 2000-2002 Audi A4, S4, and TT vehicles have driver-side frontal airbag inflators that may absorb moisture due to a manufacturing issue. Moisture can cause the airbag to deploy improperly in a crash.

If the airbag does not deploy properly during a crash, it may not adequately protect the driver, increasing the risk of serious injury or death.

Authorized Audi dealers will replace the driver frontal airbag inflator with an alternative inflator at no cost. Owners who received a notification letter mailed November 2, 2021 can contact Audi customer service at 1-800-253-2834 (Volkswagen recall number 69CJ). You can also check your vehicle's VIN for open recalls.
