NHTSA recall 15V636000

What's wrong: The affected vehicles received replacement seat base assemblies during repair service, but during the work, the seat position target bracket may not have been transferred from the old seat to the new one. Without the seat position target bracket, the air bag may deploy at a higher intensity than necessary.

Why it matters: An air bag that deploys at a higher than intended level increases the risk of injury during a crash.

The fix: Gm will notify owners, and dealers will inspect the vehicles and, if necessary, install a seat frame equipped with a target bracket, free of charge. The recall began on December 28, 2015.
