NHTSA recall 14V265000

What's wrong: Affects vehicles equipped with A 220 amp generator (rpo kw5). In the affected vehicles, the retention clips that attach the fuse block to the vehicle body can become loose allowing the fuse block to move out of position. If this occurs, exposed conductors in the fuse block may contact the mounting studs or other metallic components, causing a short to ground event.

Why it matters: This could result in an arcing condition, and combustible materials located nearby could ignite and result in an engine compartment fire.

The fix: Gm will notify owners, and dealers will inspect the fuse block to verify that it is properly secured, repairing it as necessary, free of charge. The recall began on July 30, 2014.
