The 2009HUMMERH3 carries 94 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 2 crashes, 6 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 2009 H3 is electrical system with 30 filings, followed by engine (9) and unknown or other (7). 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 2009 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.

Was doing a frame inspection on my hummer h3. Turns out the rear left frame rail is completely rusted through. And there are parts hanging on by a thread. I have found many complaints online about rust in this exact spot( rear left frame). I believe this issue should be dealt with immediately. Someone could be killed. The car is not that old and no other car of this age and mileage has this amount of rust penetration through the frame. GM needs to be held accountable. THIS IS A MANUFACTURING DEFECT.
The contact owns a 2009 Hummer H3. The contact stated that the vehicle failed to immediately start, and the security warning light illuminated. After several attempts, the vehicle was started. The contact stated that the failure was intermittent but had become more frequent. The cause of the failure was not yet determined. The manufacturer and local dealer were notified of the failure, but no assistance was provided. The failure mileage was 97,000.
Mileage: 97,000
The contact owns a 2009 Hummer H3. The contact stated that while attempting to start the vehicle, the vehicle failed to start. The contact waited for a while before the vehicle started. The contact stated that the vehicle was slow to start. The contact stated that while her husband was at the store, he waited for 15 minutes before the vehicle started. There were no warning lights illuminated. The vehicle was taken to an independent mechanic who replaced the battery and starter, but the failure recurred. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was unknown.
I was having the truck inspected per state yearly requirements and when the shop lifted the truck, the bed bent backward. The frame was rusted out on both sides.
Traveling at approximately 35mph on inner city road in my 2009 Hummer H3T, both driver and passenger side curtain airbags deployed without any warning, no collision or accident, system went into crash mode and fired seat belt tensioners. Pictures taken of the exterior conditions and terrain/road conditions. Luckily just driver was in vehicle no other passengers. Vehicle taken to GMC dealer and inspected by service tech and insurance company. Multiple other Hummer H3(T) owners have experienced similar incidents. Lack of parts OEM or after market make repairs unlikely will be contacting GM.

RECENTLY MY 2009 HUMMER H3, HAS BEEN ACTING STRANGE. WHILE DRIVING DOWN THE ROAD, WARNING LIGHTS WILL FLASH, WILL BEEP, (TRACTION CONTROL, ABS, SERVICE 4WD, CHANGE OIL, SERVICE TPM), ALL THE WHILE ALL THINGS ELECTRICAL STOPS WORKING SUCH AS HEADLIGHTS, BRAKE LIGHTS, BLOWER FAN, HEATED SEAT, TURN SIGNALS, AND ALL THIS WHILE DRIVING DOWN THE ROAD AT NORMAL SPEED. IT STARTED DOING THIS AS THE WEATHER GOT COLDER BUT THIS H3 IS WELL MAINTAINED AND IS GARAGE KEPT AND I ONLY USE IT TO DRIVE TO AND FROM WORK. IT IS NOW A SAFETY HAZARD AND WITH THESE ISSUES WILL NOT BE ABLE TO TRADE IT IN. I HAVE NO IDEA WHERE TO START IN ORDER TO FIX IT. AFTER FINALLY DRIVING FOR 30 MIN OR SO SOMETIMES IT WILL FINALLY QUIT MESSING UP AND ACT NORMAL.
