NHTSA recall 14V542000

What's wrong: In the affected vehicles, the electrical terminals of the fuel pump module may overheat resulting in the melting of the flange material.

Why it matters: If the flange melts, a hole may be created allowing the fuel pump to leak fuel, causing the vehicle to stall, increasing the risk of a vehicle crash. Additionally, leaking fuel in the presence of an ignition source increases the risk of a fire.

The fix: Gm will notify owners, and dealers will replace the fuel module and fuel tank jumper harness, free of charge. Gm sent out interim notices in late October. The recall began on March 12, 2015.
