The short version
General Motors LLC reported a problem with the curtain inflator. Here is what owners need to know.
The diffuser component of the Roof-Rail Air Bag (RRAB) inflator may not have been properly crimped to the inflator and could separate from the inflator during air bag deployment.
If the diffuser separates from the inflator during deployment, RRAB performance may be degraded, increasing the risk of injury in a crash.
GM will notify owners, and dealers will replace the suspect RRAB modules, free of charge.
