IllustrationCERTAIN TIMES WHILE DRIVING, THE TRACTION ASSIST COMES ON, AND ALL POWER IS LOST TO THE ENGINE. LIGHTS ARE STILL ON, CAR IS STILL ON, BUT GAS DOES NOT ACCELERATE AND CAR IS HARD TO STEER. I HAVE HAD TO PULL OVER 6 TIMES IN THE LAST FEW MONTHS, TURN THE CAR OFF, RESTART AND HOPE IT DOES NOT HAPPEN AGAIN.

414V542000 · Fuel System, Gasoline:delivery:fuel Pump
Sep 9, 2014
General Motors LLC (GM) is recalling certain model year 2004-2007 Cadillac CTS-V vehicles manufactured October 6, 2003, to March 15, 2007, and 2006-2007 Cadillac STS-V vehicles manufactured June 23, 2005, to March 15, 2007. In the affected vehicles, the electrical terminals of the fuel pump module may overheat resulting in the melting of the flange material.
Consequence & remedy
Consequence: 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.
Remedy: 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. Owners may contact Cadillac customer service at 1-800-458-8006. GM's number for this recall is 14405.
