The 2008HUMMERH3 carries 153 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 4 crashes, 8 fires, 5 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2008 H3 is electrical system with 31 filings, followed by engine (18) and air bags (13). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 2 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 2 investigation files overlapping the 2008 H3. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

The last dealership I went to they advised to come th the dealership but when I got there nobody wasnât trying to work there instead the said that it was going to be hard to work on it cause nobody work on those cars anymore and then they said they were going to order the part but never call me back for it.

Engine was replaced at 163,000 miles now at 168,000 miles the frame is rusted beyond repair and is about to give at any moment nothing really left near rear axels. This could have definitely caused a horrible accident to myself or others having a big car just give way and collapse. Took it to mechanic who warned me first then next day took it to body shop that said nothing could be done. Basically both said get rid of it for parts as fast as you can and donât look back. After the body shop guy actually showed me the rusted out areas i was scared to even drive it like the 10miles back to my house. It sucks after spending all that money on an engine and now having this issue and now having to buy a new car.

I saw a vehicle on sale in Indiana, via AutoTrader. I got a loan from a Federal Credit Union in Huntsville, Al. I can't get brakes repaired because frame is highly unreliable to be lifted. I need your assistance, please and Thank you [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
I was not involved in an incident. The rear frame of this vehicle has rusted 90% away. if it were driven any further the rear axel will fall off. I was towing a boat and it and the axel and rear bumper could have flown off the vehicle. I had no idea the extent of damage. I've owned the vehicle for 11 years. I've read that other Hummer h3 owners have had the axel fall off. Please let other Hummer h3 owners know how severe this can be. Every northern tier state vehicle 2008 and older with 146,400 miles can not have this dangerous of a situation. I've attached a 2011 Buick lacrosse recall of a friend. This truly is a hazard. I had no idea how bad it is.
Vehicle will not crank. After 10-12 minute wait vehicle cranks. According to symbol this is an anti-theft lockdown. But it happens repeatedly for no reason. Has happened 5 times in 6 days. My concern is this could happen during an emergency or in a dangerous place for a woman alone (dark deserted parking lot for instance). For this reason I am very conscious of where I park, but the 1st time it happened, with no warning, was terrifying. From what I have read even replacing the ignition does not solve the issue permanently, the same thing begins to happen again.
THE ANTILOCK SAFETY IS PREVENTING ME FROM STARTING MY VEHICLE. WHEN IT DOES START, AND I GO TO AN INTERSECTION TO TURN THE TRUCK WILL THEN STALL OUT. IT CAN CAUSE A WRECK. IT IS A HUGE SAFETY ISSUE, TIME CONSUMING, AND MONEY CONSUMING WHEN I HAVE TO WAIT 10 MINUTES TO TRY TO START MY TRUCK, OR IT DOESN'T START, I HAVE TO REPLACE IT FOR $450+ WHICH I DON'T HAVE TO REPLACE THE IGNITION SWITCH AND IT'S DANGEROUS BECAUSE IF IT DOES LET IT START I HAVE TO BE CAREFUL BECAUSE IT WILL STALL OUT ON ANY GIVEN SECOND CAUSING A CATASTROPHE!!! THERE ARE MULTIPLE PEOPLE WITH THE SAME ISSUES ON THEIR VEHICLES. GM SHOULD BE RESPONSIBLE TO DO A RECALL AND FIX THIS PROBLEM.
