I EXPERIENCED WATER LEAKING AND RUNNING DOWN THE INSIDE OF BOTH OF THE FRONT DOORS. IN ADDITION, THE DASH LIGHTS FADED IN AND OUT INTERMITTENTLY, THE CLOCK LOSES TIME, THE NAV AND RADIO SCREEN BLACKS OUT, AND THE STABILITY TRAK SERVICE LIGHT COMES ON. THEY "FIXED" THE WATER LEAK BY EXTENDING THE DRAIN HOSES ON THE SUNROOF. ALL OF THE ELECTRICAL PROBLEMS WERE FOUND TO BE RELATED TO THE LEAKS IN THE SUNROOF. ON SEPT. 18THE OF THE SAME YEAR, I RETURNED THE VEHICLE TO HAVE A RECALL ON THE SUNROOF DRAINS PERFORMED. I ADVISED THAT I WAS STILL HAVING THE SAME ELECTRICAL ISSUES. A DIMMER SWITCH WAS ORDERED. ON FEB. 20, 2012 I STARTED MY VEHICLE AND HEARD A FAINT PINGING NOISE LIKE A DYING SMOKE ALARM EMITTING FROM THE PASSENGER DASH AREA. I TOOK IT TO A GMC CENTER AND WAS TOLD THAT WATER HAD LEAKED BEHIND THE DASH, CAUSING CORROSION AND A SHORT IN THE IP FUSE BOX. I HAD TO PAY ALMOST $1,000 TO HAVE THE LEAK SEALED (DESIGN FLAW) AND HAD TO HAVE A NEW ELECTRICAL BLOCK INSTALLED. I CALLED AND COMPLAINED TO GM THAT I SHOULD NOT HAVE TO PAY FOR DAMAGE THAT RESULTED FROM 1) A POOR DESIGN AND 2) DAMAGE THAT SHOULD NOT HAVE HAPPENED SINCE I HAD TAKEN THE VEHICLE IN TWICE ON PRIOR LEAKS WHICH WERE SUPPOSED TO HAVE BEEN FIXED. IT HAS BEEN THREE WEEKS AND I AM STILL GETTING THE RUN AROUND FROM GM. NOW THEY CLAIM IT WASN'T THE SUNROOF LEAKING, BUT THE DOOR. A LEAK IS A LEAK AND IT SHOULD HAVE BEEN CHECKED ON THE PRIOR SERVICE VISITS. APPARENTLY THE LEAKING HAS BEEN GOING ON FOR QUITE SOMETIME. I SEE THAT OTHERS HAVE HAD THIS SAME BAD EXPERIENCE. HERE WE BAILED OUT A COMPANY THAT WON'T BACK UP ITS PRODUCT. *TR

POWER TRAIN
DRIVING DOWN THE HIGHWAY THE TRANSMISSION FAILED. TURNS OUT THE 2007-2009 MODELS HAVE A KNOWN ISSUE OF A FAILED "WAVE PLATE". MY SON AND I WERE ALMOST IN AN ACCIDENT BECAUSE OF THIS. THE VEHICLE WAS TOWED TO THE GMC DEALER. *TR
