Autoliv, Inc. (Autoliv) is recalling certain roof rail air bag inflators with model numbers ACH4.0 (P7.5-30-325) and ACH4.0 (P3.5-30-312). The air bag inflator may fail at the weld joint, which can cause gas to leak from the inflator or result in an inflator rupture.
An inflator that ruptures may cause sharp metal fragments to enter or exit the vehicle, increasing the risk of injury. Additionally, an inflator that leaks gas may only partially inflate during a crash, increasing the risk of injury.
Vehicle manufacturers will determine the remedy for the affected vehicles. Owners may contact Autoliv customer service at 1-248-276-0722.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
