Audi A4 Recall 18V427: Passenger Airbag Inflator May Explode on Deployment

NHTSA campaign 18V427, reported June 22, 2018, 237,947 vehicles potentially affected.

What this recall means for you

The passenger-side frontal airbag inflator in these vehicles may rupture when the airbag deploys in a crash. Long-term exposure to humidity and temperature changes can degrade the propellant inside the inflator, which can cause it to explode.

An inflator explosion can send sharp metal fragments toward the driver or other occupants, which may result in serious injury or death.

Authorized Audi dealers will replace the passenger frontal airbag with an alternate remedy part at no cost to you. Owners can also contact Audi customer service at 1-800-253-2834. Check your vehicle's VIN for open recalls on the NHTSA website, since this recall supersedes earlier airbag recalls and includes some vehicles that previously had their airbag replaced.

Check whether this recall is open on your vehicle

The repair is normally free at an authorized dealer.
