I UNDERSTAND THAT 2006 CADILLAC CTS HAS A RECALL FOR AIRBAG PROBLEMS. CADILLAC DOESN'T DENY THAT THE SAME SYSTEM WAS USED IN THE STS. I'VE SEEN SEVERAL COMPLAINTS ABOUT THE SAME PROBLEM. I JUST WONDER WHY THE STS WAS NOT RECALLED. I KNEW THERE WAS NO WARRANTY, AND THAT'S WHY I CONTACTED CADILLAC. KNOWING THIS THEY SENT ME FOR A DIAGNOSTIC, WHICH WAS A WASTE OF TIME AND MONEY. THE END RESULT WAS THAT THEY SAID IT'S NOT UNDER WARRANTY. I WOULD JUST LIKE YOU TO INVESTIGATE TO SEE IF THERE SHOULD BE A RECALL. THIS IS A SAFETY ISSUE THAT CADILLAC SHOULD ADDRESS. *JS

STARTED RECEIVING A CONSTANT, "SERVICE AIR BAG" WARNING MESSAGE AFTER 125,000 MILES. THE DEALER TOLD ME THE PASSENGER PRESENCE MODULE NEEDED REPLACED. IT WILL COST $1,000 FOR THE PART, LABOR, AND PROGRAMMING. NOW I READ ON THIS FORUM THAT THE SAME ISSUE WAS FOUND ON THE CTS MODEL AND IT WAS RECALLED BY THE MANUFACTURER, BUT NOT THE STS.

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.
