Safety recalls (4)
Fuel System, Gasoline:delivery:fuel Pump 2014-09-09 · campaign 14V542000 · 10,005 vehicles
Defect: 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.
Risk: 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.
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. Owners may contact Cadillac customer service at 1-800-458-8006. GM's number for this recall is 14405.
Electrical System:ignition 2014-07-02 · campaign 14V394000 · 554,328 vehicles
Defect: This defect can affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. General Motors LLC (GM) notified the agency on July 2, 2014 that they are recalling 554,328 model year 2003-2014 Cadillac CTS vehicles manufactured August 16, 2001, to April 28, 2014, and 2004-2006 Cadillac SRX vehicles manufactured March 20
Risk: If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury.
Fix: GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 15, 2014. Owners may contact Cadillac customer service at 1-800-458-8006. GM's number for this recall is 14172.

THIS FLEXING CAN BREAK THE CONNECTIONS IN THE MAT. IF THIS OCCURS, THE SENSOR MAY NOT DETECT THE PRESENCE OF A FRONT SEAT PASSENGER AND WILL DISABLE THE AIR BAG.
Risk: NON-DEPLOYMENT OF THE FRONT PASSENGER AIR BAG IN THE EVENT OF A CRASH NECESSITATING THAT AIR BAG'S DEPLOYMENT MAY REDUCE PROTECTION OF THE PASSENGER AND INCREASE THE RISK OR SEVERITY OF INJURY TO THEM.
