2007 Cadillac STS recalls

2 NHTSA recall campaigns list this model year.

  1. NHTSA 14V542000Sep 9, 2014Fuel System10,005 vehicles

    Fuel system, gasoline:delivery:fuel pump

    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.

    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.

    On certain passenger vehicles, the rear axle pinion seal does not meet all of the specifications and may experience a fluid leak.

    Risk: A rear differential failure may cause loss of motive power and possibly loss of control increasing the risk of a crash.

    Remedy: Dealers will replace the pinion seal free of charge. The recall began on february 1, 2008. Owners may contact cadillac at 1-800-458-8006 or http://www.cadillac.com; pontiac at 1-800-620-7668 or http://www.pontiac.com; and saturn at 1-800-972-8876 or http://www.saturn.com.
