2010 Hummer H3

Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

Latest Jul 1, 2015
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

My transfer case established a large fluid leak so I inspected it, the findings was a large hole in the main housing on the transfer case fluid was leaking out. The transfer case was removed and disassembled, and found that the 2 screws that hold the chain guide to the housing had backed out or fell out and let the chain guide fall down in to the gear mechanism and ground it up and broke the main case. In result was the quarter size hole in the housing of the transfer case allowing liquid to escape and damage the housing. Leaving me without a vehicle.

THE VEHICLE SOMETIMES WILL NOT START DUE TO A PROBLEM WITH THE SECURITY SENSOR IN THE IGNITION SWITCH. THIS IS WHEN STARTING UP THE VEHICLE AND WILL ONLY PERIODICALLY OCCUR. THE SECURITY SYSTEM LIGHT COMES ON AND YOU HAVE TO WAIT 10 MINUTES TO START THE VEHICLE, THEN IT WILL START. IT HAS HAPPENED IN THE SUMMER AND NOW THE WINTER.

Fire reported

MY HEATING AND AC BLOWER MOTOR STOPPED WORKING ON A VEHICLE THAT HAS LESS THAN 31K MILES ON IT. THE ESTIMATED REPAIR COSTS ARE 500$, NOT INCLUDING THE TOW, BEING THAT IT IS THE MIDDLE OF WINTER AND THE CLOSEST DEALERSHIP IS 20 MILES AWAY. ADDITIONALLY, THE TIME OFF OF WORK AND EBING WITHOUT A CAR FOR A WEEK. I HAVE HEAVILY RESEARCHED THIS ISSUE AND IT HAS BEEN REPORTED THOUSANDS OF TIMES AND IS A WELL KNOWN ISSUE AND GM HAS NOT ISSUED A RECALL. THE PROBLEM IS THAT A FAULTY ELECTRICAL SHORT CAUSES A WIRING HARNESS TO MELT, (SMOKING) WITH A BURNING SMELL AND BLACK RESIDUE. THIS IS A MAJOR FIRE HAZARD AND THE RECOMMENDED FIX FROM THE DEALERSHIP ONLY REPLACES THE HARNESS, BUY DOES NOT ADDRESS THE CORE ISSUE CAUSING THE FIRE HAZARD. THIS IS LIKE REPLACING BURNT DRYWALL TO ADDRESS FAULTY HOUSE WIRING . *TR
