Official recalls
6Sep 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.
Jul 2, 2014
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.
Consequence & remedy
Consequence: 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.
Remedy: 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.
Mar 17, 2010
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.
Consequence & remedy
Consequence: THE BRAKE HOSE-TUBE INTERFACE MAY RUPTURE SUDDENLY WITHOUT PRIOR WARNING AND INCREASE VEHICLE STOPPING DISTANCE MAY OCCUR INCREASING THE RISK OF A CRASH.
Remedy: DEALERS ARE TO REPLACE BOTH FRONT BRAKE HOSE ASSEMBLIES FREE OF CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN DURING MAY 2010. OWNERS MAY CONTACT CADILLAC AT 1-866-982-2339 OR AT THE OWNER CENTER AT WWW.GMOWNERCENTER.COM.
Jan 20, 2005
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.
Consequence & remedy
Consequence: A PERSON POSITIONED FOR DRIVING MAY RECEIVE MINOR INJURIES, SUCH AS ABRASIONS, FROM CONTACT WITH A DEPLOYING AIR BAG.
Remedy: DEALERS WILL REPLACE THE SENSING AND DIAGNOSTIC MODULE FREE OF CHARGE. THE RECALL BEGAN ON MAY 20, 2005. OWNERS MAY CONTACT CADILLAC AT 1-866-982-2339.
Jun 9, 2004
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.
Consequence & remedy
Consequence: IF THE CONTROL ARM SEPARATES FROM THE KNUCKLE, THE AFFECTED CORNER OF THE VEHICLE WILL DROP AND THE CONTROL ARM WOULD BE FORCED DOWNWARD, CONTACTING THE WHEEL. THE AFFECTED WHEEL COULD TILT OUTWARD AND CREATE A DRAGGING ACTION THAT WOULD TEND TO SLOW THE VEHICLE AND CREATE A TENDENCY FOR THE VEHICLE TO TURN IN THE DIRECTION OF THE AFFECTED WHEEL. IN EXTREME SITUATIONS, THE AFFECTED WHEEL ASSEMBLY COULD SEPARATE FROM THE VEHICLE. SEPARATION OF THE WHEEL ASSEMBLY WOULD ALSO SEVER THAT WHEEL;S HYDRAULIC BRAKE HOSE AND RESULT IN DIMINISHED BRAKING PERFORMANCE OF THE VEHICLE, WHICH COULD RESULT IN A CRASH.
Remedy: DEALERS WILL INSPECT THE BALL STUD JOINTS AND MEASURE THE TORQUE OF THE NUT FOR ALL FRONT LOWER CONTROL ARMS IN ALL MODELS AFFECTED AS WELL AS THE REAR LOWER CONTROL ARMS ON THE XLR AND CORVETTE. IF THE TORQUE IS NOT AT SPECIFICATION, THE DEALERS WILL REPLACE THE BALL STUD, THE KNUCKLE, AND THE NUT. IF THE TORQUE IS AT SPECIFICATION, THE DEALERS WILL REPLACE THE NUT/WASHER ASSEMBLY ONLY. THE RECALL WILL BEGIN ON AUGUST 25, 2004. OWNERS SHOULD CONTACT CADILLAC AT 1-866-982-2339 OR CHEVROLET AT 1-800-630-2438.
Sep 29, 2003
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.
Consequence & remedy
Consequence: IN SOME CRASH CONDITIONS, THE SEAT COULD PIVOT REARWARD AND ITS OCCUPANT OR A REAR SEAT OCCUPANT COULD BE INJURED MORE SEVERELY.
Remedy: DEALERS WILL ENSURE THAT BOTH FRONT ANCHOR TABS ARE FULLY SEATED IN THE FLOOR PAN REINFORCEMENT SLOTS. OWNER NOTIFICATION BEGAN SEPTEMBER 19, 2003. OWNERS SHOULD CONTACT GM AT 1-800-458-8006.

Status: closed (inferred from source dates) · Power Train:driveline:differential Unit
IN JULY OF 2007 THE OFFICE OF DEFECTS INVESTIGATION (ODI) OPENED PE07-037 TO INVESTIGATE ALLEGATIONS THAT THE REAR DIFFERENTIAL MAY FAIL CAUSING A LOSS OF MOTIVE POWER, AND IN SOME INSTANCES A LOSS OF CONTROL, IN MODEL YEAR (MY) 2004 THROUGH 2006 CADILLAC CTS, CTS-V, AND STS VEHICLES.AS A RESULT OF THAT INVESTIGATION GM ISSUED RECALL 07V-589 TO CORRECT A LEAKING PINION SEAL PROBLEM.EA07-017 WAS OPENED TO INVESTIGATE COMPLAINTS OF FRACTURED REAR DIFFERENTIAL HOUSINGS OR REAR HALF SHAFTS IN HIGH PERFORMANCE CADILLAC CTS-V VEHICLES.ACCORDING TO GM, THESE FAILURES RESULTED FROM THE CUMULATIVE DAMAGE FROM MULTIPLE POWER HOP EVENTS THAT CAN OCCUR DURING VERY AGGRESSIVE DRIVING. IN FEBRUARY 2008 INVESTIGATORS FROM ODI MET WITH GM REPRESENTATIVES TO CONDUCT TESTING OF THE SUBJECT CTS-V VEHICLES.DURING THE TESTING THE SUBJECT VEHICLES WERE SUBJECTED TO CONSIDERABLE TORSIONAL FORCES FROM STANDING STARTS AND WHILE DRIVING.POWER HOP OCCURRED DURING SOME OF THE MOST AGGRESSIVE DRIVING MANEUVERS.THE TESTING DID NOT RESULT IN FAILURE OF ANY REAR DRIVETRAIN COMPONENTS.THE ENGINEERING DESIGN AND TESTING DATA SUPPLIED TO ODI BY GM AND THE RESULTS OF THE TESTING CONDUCTED BY ODI TEND TO SUPPORT GM'S POSITION THAT THE DIFFERENTIAL DESIGN IS NOT DEFECTIVE. COMPLAINTS LISTED IN THE FAILURE REPORT DO NOT INCLUDE THOSE INDICATIVE OF FAILURE OF THE REAR PINION SEAL IN CTS-V VEHICLES COVERED BY RECALL 07V-589. FURTHER INVESTIGATION IN THIS MATTER WOULD NOT BE AN EFFICIENT ALLOCATION OF AGENCY RESOURCES.ACCORDINGLY, THIS INVESTIGATION IS CLOSED.SEE ATTACHED CLOSING REPORT FOR FURTHER DETAILS.
