Issue: 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.

SERVICE AIRBAG ON THE DASH / AIRBAG LIGHT ON
MY CAR HAS BEEN DIAGNOSED AS HAVING 'EXTENDED CRANK'. MY LOCAL CHEVY DEALER MADE APPROXIMATELY FIFTEEN ATTEMPTS AT FIXING IT TO NO AVAIL. I'M TOLD IT'S THE CHECK VALVE, BUT I HAVE NOT HAD THAT DONE BECAUSE ALL ATTEMPTS BY THE DEALER DIDN'T WORK; E.G., NEW COMPUTER (AND REMOVED), BATTERY (AND REMOVED), FUEL PUMP, ETC. VERY FRUSTRATING AND I FEEL IT'S A MATTER OF HEALTH AND SAFETY BECAUSE THE CAR ALMOST NEVER STARTS ON THE FIRST ATTEMPT, AND SOUNDS LIKE IT'S A DEAD BATTERY.
I UNDERSTAND THAT 2006 CADILLAC CTS HAS A RECALL FOR AIRBAG PROBLEMS. CADILLAC DOESN'T DENY THAT THE SAME SYSTEM WAS USED IN THE STS. I'VE SEEN SEVERAL COMPLAINTS ABOUT THE SAME PROBLEM. I JUST WONDER WHY THE STS WAS NOT RECALLED. I KNEW THERE WAS NO WARRANTY, AND THAT'S WHY I CONTACTED CADILLAC. KNOWING THIS THEY SENT ME FOR A DIAGNOSTIC, WHICH WAS A WASTE OF TIME AND MONEY. THE END RESULT WAS THAT THEY SAID IT'S NOT UNDER WARRANTY. I WOULD JUST LIKE YOU TO INVESTIGATE TO SEE IF THERE SHOULD BE A RECALL. THIS IS A SAFETY ISSUE THAT CADILLAC SHOULD ADDRESS. *JS
LEAKS FUEL IF YOU FILL THE TANK TO CAPACITY. THIS WAS AN EARLIER RECALL, EXACT SAME THING HAPPENING AGAIN.
CERTAIN TIMES WHILE DRIVING, THE TRACTION ASSIST COMES ON, AND ALL POWER IS LOST TO THE ENGINE. LIGHTS ARE STILL ON, CAR IS STILL ON, BUT GAS DOES NOT ACCELERATE AND CAR IS HARD TO STEER. I HAVE HAD TO PULL OVER 6 TIMES IN THE LAST FEW MONTHS, TURN THE CAR OFF, RESTART AND HOPE IT DOES NOT HAPPEN AGAIN.
PUMP IS GOING OUT

PURCHASED 2006 CADILLAC STS BUILT ON JUNE 21 2005 LAST DAY OF 2005 MODEL. CAR HAS HAD ALL THE ISSUES THAT 22005 VEHICLE HAD. JUNE 23RD 2005 WAS FIRST DAY OF PRODUCTION. AT EVERY CORNER VIN # ARE NOTED HOWEVER FOR THIS MODEL THE BUILD DAYS WHICH NOTED BY CADILLAC ARE THE IMPORTANT FACTORS. I DON'T THINK COINCIDENCE THAT I'VE BEEN COMPANLING TO CADILLACAND ASKING FOR HELP WITH ZERO HELP. CATALYTIC CONVERTER WAS EXTENDED WARRANTEE FOR 200000 AND 12 YEARS HOWEVER CADILLAC ALWAYS SAYS VIN EVEN THOUGH DATES ARE THE ONLY THING NOTED. I HAVE CALLED AND E,AIL FOR 3 YEARS. MY CAR IS OFF ROAD AND THEY HAVE REFUSED TO LOOK AND EVEN IF I PAID THEY WOULDN'T GUARANTEE THEY WOULD EVEN LOOK AT THE ISSUES. MY CAR IS IN ABSOLUTE LIMBO NEITHER A 2006 OR 05 OR WHATEVER. THEY HAVE REFUSED EVERY STEP EVEN THOUGH IT WAS BASED ON RECALLS
