361 reportsI BOUGHT THIS H3 HUMMER USED AND IT RAN GOOD UNTIL LAST YEAR. IT WOULD NOT START AT DIFFERENT TIMES BUT AFTER YOU WAITED 10 MINUTES, IT WOULD START. WE JUST PAID 1300.00 TO HAVE THE FUEL PUMP REPLACED LAST WEEK. NOW IT WON'T START AGAIN. I HAVE SEEN MANY COMPLAINTS ON THIS AND THERE SHOULD BE A RECALL ON THIS PROBLEM.
THE PADLOCK SYSTEM THAT THE CAR HAS IT PREVENTS THE CAR TO START AND LEAVES YOU STOPPED FOR 10 MINUTES. IT'S BEEN DOING IT LATELY MORE IN THE MORNING OR WHEN THE CAR HASN'T BEEN MOVED IN AWHILE. THE SECURITY ICON IN THE DASHBOARD BLINKS WHEN THE PASSLOCK SECURITY ENABLES AND THAT LEAVES THE CAR WITHOUT STARTING.

MY H3 HAS BEEN HAVING ISSUES WITH RANDOM WARNING LIGHTS APPEARING. OFTEN MULTIPLE LIGHTS LIKE ENGINE, CHECK TRANSMISSION AND TRACTION. EACH TIME I WOULD TAKE IT TO MECHANIC AND WOULD NOT FIND A PROBLEM ANYTHING IN ENGINE. THEN THE 4 WHEEL LIGHT DRIVE WOULD NOT ILLUMINATE. THE MOST RECENT PROBLEM IS MUCH WORST... WHILE THE CAR WAS NOT RUNNING THE RIGHT TURN SIGNAL CAME ON BY ITSELF. I GOT IN IT TO DRIVE IT TO LOCAL MECHANIC AND WHILE DRIVING IT ACTIVATED THE BRAKE AND MANY WARNING LIGHTS WERE FLASHING AS WELL. VERY DISTURBING. I HAVE OWNED THIS VEHICLE SINCE 2006 NOW IT HAS 125000 MILES. I HAVE KEPT A COMPLETE HISTORY OF MAINTENANCE THAT INCLUDES OIL CHANGED EVERY TIME BETWEEN 3500-5000 MILES

THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED. THE DEALER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS NOT AVAILABLE.
THE HOOD COVER IS LOOSE AND RATTLES WHEN DRIVING. IT MAKES ME AFRAID AS I DRIVE THE INTERSTATE EVERYDAY AND IT SEEMS AS IF IT IS GOING TO FLY OFF. I ALSO LOSE POWER OR IT FAILS TO START DUE TO SOME TYPE OF ELECTRICAL ISSUE, BRAKES GO, STEERING GOES AND ALL LIGHTS ON CLUSTER LIGHT UP
ELECTRICAL PROBLEMS, EITHER THE VEHICLE WIL NO START DUE TO THE ANTI-THEFT SYSTEM OR I WILL LOSE ALL POWER WHEN DRIVING.
MY 2006 H3 HAS SPORADIC ISSUES WITH STARTING FOR A FEW YEARS NOW. WHEN I TRY TO START IT, IT WILL CRANK FINE BUT WILL NOT START. IF I WAIT APPROXIMATELY 10 MINUTES & TRY AGAIN, IT STARTS WITH NO PROBLEMS. DURING THIS ISSUE, EVERYTHING ELSE WORKS IN THE VEHICLE (RADIO, LIGHTS, ETC..).

MY 2006 H3 HAS SPORADIC ISSUES WITH STARTING FOR A FEW YEARS NOW. WHEN I TRY TO START IT, IT WILL CRANK FINE BUT WILL NOT START. IF I WAIT APPROXIMATELY 10 MINUTES & TRY AGAIN, IT STARTS WITH NO PROBLEMS. DURING THIS ISSUE, EVERYTHING ELSE WORKS IN THE VEHICLE (RADIO, LIGHTS, ETC..). I'VE HAD IT CHECKED BY SEVERAL MECHANICS & REPLACED LOTS OF PARTS BUT DIDN'T HELP THIS ISSUE AT ALL. I HAVE READ MANY COMPLAINTS REFERENCE THIS SAME EXACT ISSUE ONLINE & THROUGH NHTSA BUT NOBODY HAS HAD ANY POSITIVE RESPONSES. THIS IS A MAJOR ISSUE THAT SHOULD BE TAKEN CARE OF BY GM AS A RECALL. I WILL BE PART OF THIS CLASS ACTION LAWSUIT THROUGH THESE THREADS RELATED TO THIS HUMMER H3 ISSUE. THANK YOU & WAITING TO HEAR ABOUT THIS TERRIBLE GM ISSUE.

10V179000 · Structure:body:hood
Apr 30, 2010
GM IS RECALLING CERTAIN MODEL YEAR 2006 THROUGH 2010 HUMMER H3 VEHICLES. SOME OF THESE VEHICLES HAVE A CONDITION IN WHICH THE INTEGRAL CLIP-TABS ON THE LOUVER ON THE HOOD MAY FRACTURE, CAUSING THE HOOD LOUVER RATTLE AGAINST THE HOOD AND BECOME LOOSE. IF THIS INDICATOR IS UNNOTICED, ADDITIONAL CLIPS COULD FRACTURE AND THE HOOD LOUVER COULD DETACH FROM THE VEHICLE.
Consequence & remedy
Consequence: IF THE VEHICLE IS BEING DRIVING WHEN THIS OCCURS, IT COULD STRIKE A FOLLOWING VEHICLE AND CAUSE INJURY AND/OR PROPERTY DAMAGE.
Remedy: DEALERS WILL APPLY AN ADHESIVE TO THE HOOD LOUVER TO SECURE IT TO THE HOOD. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON APRIL 12, 2010. OWNERS MAY CONTACT HUMMER AT 800-732-5493 OR AT THE OWNER CENTER AT WWW.GMOWNERCENTER.COM.
06V417000 · Air Bags:frontal
Oct 31, 2006
CERTAIN VEHICLES ORIGINALLY BUILT WITH CLOTH SEATS THAT WERE EQUIPPED WITH AN AUTOMATIC AIR BAG PASSENGER SENSING SYSTEM AND LATER REUPHOLSTERED WITH AFTERMARKET LEATHER SEAT COVER KITS ARE INVOLVED. TESTING HAS INDICATED THAT THE AFTERMARKET LEATHER SEAT COVERS CAN CAUSE THE PASSENGER SENSING SYSTEM TO MALFUNCTION.
Consequence & remedy
Consequence: IF THE PASSENGER SENSING SYSTEM MALFUNCTIONS, THE FRONT AIR BAG ON THE PASSENGER SIDE MAY BE DISABLED WHEN IT SHOULD BE ENABLED, OR ENABLED WHEN IT SHOULD BE DISABLED. IN EITHER CASE, IN THE EVENT OF A CRASH THAT REQUIRES AIR BAG DEPLOYMENT, A FRONT PASSENGER'S LEVEL OF INJURY MAY BE INCREASED.
Remedy: BECAUSE A REPLACEMENT LEATHER SEAT COVER THAT IS COMPATIBLE WITH THE PASSENGER SENSING SYSTEM IS NOT AVAILABLE, GENERAL MOTORS (GM) WILL REPURCHASE THESE VEHICLES IN ACCORDANCE WITH THE TERMS STATED IN GM'S LETTER TO OWNERS. THE RECALL BEGAN ON NOVEMBER 6, 2006. OWNERS SHOULD CONTACT GM AT 1-877-477-1022 TO BEGIN THE PROCESS OF REPURCHASING THEIR VEHICLE.
