THIS PROBLEM STARTED OVER A YEAR AGO AND I HAVE HAD IT TO THE DEALER TWICE AND THEY CAN NO FIND THE PROBLEM BECAUSE THERE ARE NO CODES IN THE CAR. WHILE DRIVING THE CAR IT SHUTS DOWN AND YOU LOSE EVERTHING LIGHTS, TURN SINGLES, HAZARDS,THE DASH GOES TOTALY OUT AND THE ENGINE STOPS THE BEST YOU CAN DO IT TO PULL IT OVER TO THE SIDE OF THE ROAD AND HOPE YOU DON'T GET HIT. I HAVE HAD THIS HAPPEN IT TOWN DRIVING AND ON THE HIGHWAY SO IT HAS NOTHING TO DO WITH SPEED. I HAVE LOANED MY CAR TO OTHER PEOPLE AND IT HAS HAPPENED TO THEM SO IT IS NOT THE DRIVER. I WILL HAPPEN AND YOU PULL OVER PUT THE CAR IN PARK AND IT STARTS RIGHT UP AND YOU CAN CONTINUE DRIVING AND IT MAY HAPPEN A MILE UP THE ROAD OR IT MAY NOT HAPPEN FOR A WEEK OR A MONTH LATER AND STILL NO CODES.

Official recalls
4Sep 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.
Dec 20, 2007
ON CERTAIN PASSENGER VEHICLES, THE REAR AXLE PINION SEAL DOES NOT MEET ALL OF THE SPECIFICATIONS AND MAY EXPERIENCE A FLUID LEAK.
Consequence & remedy
Consequence: 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.
Jan 25, 2006
CERTAIN VEHICLES EQUIPPED WITH V6 ENGINES MAY HAVE A CONDITION WHERE FUEL IS NO LONGER SUPPLIED TO THE ENGINE. THIS CONDITION OCCURS WITHOUT THE ILLUMINATION OF THE FUEL LEVEL LOW INDICATOR LIGHT OR THE WARNING CHIME.
Consequence & remedy
Consequence: IF THE ENGINE STOPS RUNNING, THE OPERATOR WILL NOT BE ABLE TO RESTART THE VEHICLE WHICH COULD INCREASE THE RISK OF A CRASH.
Remedy: DEALERS WILL REPROGRAM THE ELECTRONIC CONTROL MODULE (ECM) WITH NEW SOFTWARE FREE OF CHARGE. OWNERS WERE NOTIFIED IN DECEMBER 2005 AND ASKED TO MAINTAIN AT LEAST 1/4 OF A TANK FUEL LEVEL TO AVOID THIS CONDITION UNTIL THE PARTS ARE AVAILABLE. THE PARTS ARE NOW AVAILABLE, OWNER RENOTIFICATION BEGAN ON MARCH 23, 2006. OWNERS MAY CONTACT CADILLAC AT 1-866-982-2339.
Jan 13, 2006
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH ALL WHEEL DRIVE AND A 3.6L V6 ENGINE, THE TORQUE MONITORING FUNCTIONS OF THE ELECTRONIC THROTTLE CONTROL (ETC) ARE NOT ENABLED. THESE FUNCTIONS CAN LIMIT ENGINE SPEED AND TORQUE IF UNUSUAL ENGINE CONTROL MODULE (ECM) HARDWARE OR SOFTWARE FAILURES OCCUR.
Consequence & remedy
Consequence: WITHOUT THESE FUNCTIONS ENABLED, A PERSISTENT ECM FAILURE COULD RESULT IN A THROTTLE OPENING GREATER THAN COMMANDED BY THE DRIVER AND A CRASH COULD OCCUR.
Remedy: DEALERS WILL REPROGRAM THE ECM ON THESE VEHICLES FREE OF CHARGE. THE RECALL BEGAN ON JANUARY 24, 2006. OWNERS MAY CONTACT CADILLAC AT 1-866-982-2339.
