NHTSA recall 17V412000

What's wrong: The affected vehicles received a replacement headliner as part of a repair. These service parts might not have had impact energy-absorbing foam blocks attached. As such, these vehicles fail to comply with the requirements of federal motor safety standard (fmvss) number 201, "occupant protection in interior impact."

Why it matters: If the service parts do not have energy-absorbing foam blocks, there may be an increased risk of occupant injury in the event of a crash.

The fix: Gm will notify owners, and dealers will replace the headliner assembly, free of charge. The recall began on July 28, 2017.
