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.
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, 2003, to August 11, 2006. In these models, the weight on the key ring and/or road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.
GENERAL MOTORS HAS NOTIFIED NHTSA OF A DEFECT IN CERTAIN MODEL YEAR 2003-2007 CADILLAC CTS VEHICLES CURRENTLY REGISTERED IN OR ORIGINALLY SOLD IN CONNECTICUT, DELAWARE, ILLINOIS, INDIANA, IOWA, MAINE, MARYLAND, MASSACHUSETTS, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WASHINGTON D.C., WEST VIRGINIA AND WISCONSIN. SOME OF THESE VEHICLES HAVE A CONDITION IN WHICH THE FRONT BRAKE HOSE FITTING AT THE CALIPER MAY CORRODE DUE TO SNOW OR WATER, CONTAINING ROAD SALT OR OTHER CONTAMINANTS, ENTERING AND BEING RETAINED IN THE ROUTING SLEEVE. IF THE FITTING CORRODES SIGNIFICANTLY, THE BRAKE HOSE-TUBE INTERFACE MAY DEVELOP A LEAK.
ON CERTAIN PASSENGER VEHICLES, AN INTERACTION BETWEEN THE SENSING AND DIAGNOSTIC MODULE AND VEHICLE'S ELECTRICAL SYSTEM MAY CAUSE THE DRIVER'S FRONTAL AIR BAG AND/OR ROOF-MOUNTED SIDE IMPACT AIR BAG TO DEPLOY WHEN THE IGNITION KEY IS TURNED TO THE "ON" POSITION.
ON CERTAIN PASSENGER VEHICLES INVOLVED IN THIS CAMPAIGN, THE LOWER CONTROL ARM BALL STUD NUT/WASHER ASSEMBLIES WITH WASHERS WERE MADE OF THE WRONG MATERIAL. THE WASHERS MAY FRACTURE AND BECOME LOOSE OR FALL AWAY FROM THE VEHICLE, REDUCING CLAMP LOAD. SEPARATION OF THE CONTROL ARM BALL STUD AND STEERING KNUCKLE, DUE TO DISENGAGEMENT OF THE TAPERED ATTACHMENT AND RETAINING NUT, IS POSSIBLE.
CERTAIN PASSENGER AND SPORT UTILITY VEHICLES FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 207, "SEATING SYSTEMS." ONE OR BOTH FRONT ANCHOR TABS FOR THE FRONT BUCKET SEATS ARE NOT ENGAGED IN THE FLOOR PAN REINFORCEMENT SLOTS. A SEAT WITH ONLY ONE TAB ENGAGED OR NEITHER ENGAGED WOULD NOT MEET THE STATIC REARWARD LOADING TEST REQUIREMENTS OF THE STANDARD.
