WE HAVE BATTLING THE PROBLEM OF THE SUNROOF LEAKING ON OUR HUMMER. THERE IS DRAIN TUBES IN THE CORNERS OF THE SUNROOF THIS WATER IS SUPPOSED TO GO DO THESE TUBES THEN ON THE GROUND. HOW EVER THIS IS NOT THE CASE. IN MOST CASES THE WATER LEAKS DOWN THE PILLARS IN THE TRUCKS DASH COMPARTMENT AND SOAKS THE CARPET ON BOTH SIDES AND THE HEAD LINER. WE HAVE HAD IT TO THE DEALERSHIP ON SEVERAL ACCESSIONS AND THEY JUST SAY THEY WERE STOP UP BUT THEY JUST LEAK THE NEXT DAY LIKE NOTHING HAS EVEN BEEN DONE. THEY CHARGE 300 DOLLARS TO DO THIS. I HAVE THE TECHNICIAN TELL ME THAT NOTHING HE HAS DONE WILL FIX THIS OFF THE RECORD..WHEN THE WATER IS POURING IN THERE IS NOTHING YOU CAN DO THE ONSTAR GOES OFF AND YOUR LIGHTS ON THE INSIDE GO DIM WE HAVE HAD THE CPU SHORT OUT DUE TO WATER THE BLOWER CONTROLLER BOTH FRONT SPEAKERS AND BEHIND THE DASH ALL THE METAL PARTS ARE COVERED IN RUST. WHEN THE ELECTRICAL PARTS SHORTED OUT THE WIRES WERE BURNT AND WE WERE DRIVING WHEN THIS HAPPENED ON ONE OCCASION AND HAD TO HAVE IT TOWED. WE HAVE TRIED EVERYTHING TAKEN IT THE DEALERSHIP DID NOT HELP. THE TRUCK IS ALWAYS DAMP INSIDE. THEN OF COURSE THE SMELL OF THE CARPETS. I EVEN HAVE CONTACTED GM AND JUST SAID TAKE TO THE DEALERSHIP AND THEY ARE GONNA CHARGE THE SAME THING. I AM SCARED FOR MY WIFE AND FAMILY TO DRIVE THIS TRUCK. WE WILL NOT EVEN LEAVE IN THE GARAGE DUE THE RISK OF FIRE. IF YOU GOOGLE THIS PROBLEM THERE IS OVER 60K TOPICS ON THIS AND FORUM AFTER FORUM ABOUT IT. AND EVERY IS SAYING THIS. IT IS OBVIOUS THAT THIS IS A DESIGN FLAW AND GM IS NOT GOING TO STAND BEHIND THIS. I THINK SOMETHING SHOULD DONE ABOUT THIS BEFORE SOMETHING VERY BAD HAPPENS TO SOMEONE IN THESE TRUCKS. I JUST WANT IT FIXED NOTHING ELSE. *TR

I HAVE OWNED THIS TRUCK SINCE 2009, AND IT SEEMS TO BE A COMMON PROBLEM WITH THE SUNROOF DRAIN TUBES CLOGGING. WHEN MY VEHICLE WAS UNDER WARRANTY, AND WAS GOING IN FOR IT'S SCHEDULED PMIS I WOULD HAVE THEM BLOW THE DRAIN TUBES OUT WITH AIR, BUT THE CLOGGING IS NOW BECOMING MORE FREQUENT, AND THE WATER IF NOT REMOVED CAN CAUSE HAVOC WITH THE CLOTH, ELECTRICAL & FLOORING. LAST WEEK I HAD A MILDEW SMELL BECAUSE OF ALL THE RAIN WE HAVE HAD, AND THE WATER BUILT UP IN THE SUNROOF DRAIN AREA. THESE TUBES ARE A DESIGN FLAW, AND THIS SHOULD ALSO BE A RECALL, AS THE WATER WILL BE THE MAIN CAUSE FOR PROBLEMS IN THIS SITUATION. *TR

THIS HAS ACTUALLY HAPPENED SEVERAL TIMES. WATER DRAINAGE FOR THE SUNROOF SYSTEM GET CLOGGED REALLY EASILY AND FAST. WATER WILL SPILL OUT FROM WATER TRAY AND WILL RUN OVER THE CEILING AND FALL THROUGH THE ROOF MIC (USED FOR ONSTAR), LOCATED DIRECTLY ABOVE THE DRIVER'S FACE. WHEN DRIVING AND TURNING, WATER WILL MOVE SIDE WAYS AND IT WILL SPILL THROUGH THE MIC AND SUNROOF WINDOW INTERIOR OPENING, SOAKING THE DRIVER WHILE DRIVING. NOT SAFE AT ALL. DRAINAGE DESIGN IS FLAW, AND IT KEEPS CLOGGING AFTER FIXING IT. *TR

AFTER HEAVY RAIN EXCESSIVE AMOUNTS OF WATER POOL INSIDE VEHICLE. DRAIN PLUGS HAVE BEEN CLEANED OUT MULTIPLE TIMES. ALTHOUGH WATER CONTINUES TO LAY INSIDE THE TRACK OF THE MOON ROOF AS WELL AS DRAIN ONTO THE FLOOR AND SOMETIMES ONTO THE DRIVER'S SIDE SEAT (DEPENDING ON HOW THE VEHICLE IS PARKED). BASED ON THE FORUMS REGARDING H3'S THIS APPEARS TO BE A COMMON PROBLEM. WHY HASN'T GM DONE ANYTHING TO RESOLVE IT??? *TR

H3 |DRAINAGE PROBLEM I PAID TO HAVE IT FIXED A YEAR AGO AND IT IS BLOCKED UP AGAIN. MY WIFE HAD THE SAME PROBLEM WITH HER H3. I HAVE HAD CARS AND TRUCKS AND HAVE NEVER HAD THIS PROBLEM BEFORE WITH THERE SUN ROOFS. I KNOW I'M NOT THE ONLY ONE OUT HERE THAT'S HAD THE SAME PROBLEM . WHEN AT THE DEALERSHIP ONE OF THE SHOP MECHANICS SAID THE DESIGN WAS A POOR CONSTRUCTION AND DESIGN.THE COMPANY SHOULD BE DOING SOMETHING ABOUT THERE DESIGN AND FIX IT OR HAVE A PROGRAM TO KEEP THEM FROM FLOODING . IT COULD LEAD TO ELECTRICAL PROBLEMS . DO TO THE WATER RUNNING DOWN OVER THE LOWER PANELS. I'M NOT HAPPY PAYING TO HAVE IT FIXED AGAIN. THIS IS JUST A BAD DESIGN ON GM PART. *TR

THE SIDE TRIMMING NEAR THE ROOF RACKS ARE CRACKED, THE GASKETS NEAR THE REAR OF THE ROOF RACKS ARE COMING APART, AND THE TRIMMING ON BOTH SIDES OF THE VEHICLE NEAR THE WINDSHIELD ARE COMING OFF AND FADED. THE BEST WAY FOR ME TO DESCRIBE WHAT IS GOING ON WITH MY VEHICLE IS BY PRESENTING SOME FORUMS THAT I READ ABOUT.............. HTTP://WWW.GMHUMMER.COM/FORUMS/SHOWTHREAD.PHP?T=796 HTTP://WWW.HUMMERFORUMS.COM/FORUM/SHOWTHREAD.PHP?T=16421 HTTP://WWW.ELCOVAFORUMS.COM/FORUMS/SHOWTHREAD.PHP?T=20479 HTTP://TOWNHALL-TALK.EDMUNDS.COM/DIRECT/VIEW/.F0E3B5A APPARENTLY, I AM NO THE ONLY ONE WHO IS HAVING ISSUES WITH THIS. NOT ONLY IS THIS ISSUE COSTLY, BUT SITUATIONS LIKE THIS SHOULD NOT BE OF THE CUSTOMERS FAULT WHEN THE VEHICLE HAS BEEN TAKEN CARE OF AS IT SHOULD. ESPECIALLY IF IT IS ONLY 4 YEARS OLD. MOLDING SHOULD NOT COME OFF A VEHICLE IN THIS MANNER AS IT COULD EVENTUALLY COME OFF AND DAMAGE SOMEONE ELSE'S PROPERTY AS DEBRIS WHILE DRIVING. *TR
