So the part that is a malfunction is the rear doors weren-€™t made with any child lock and of course one of my kids opened the door while i was driving on the highway.I have a 3 and 5 year old and it scared me so bad I had to hurry and pull the hummer over and park and just held my son. I couldn-€™t even drive after that because of how bad it traumatized me. My mom had to come get and take me and my kids home and drive my hummer back home. Even though we didn-€™t crash or one of my kids didn-€™t fall out.it-€™s still a very serious safety hazard. I reached out to gm to see what my options were and there response was how gm made child locks in 2007 and up and that-€™s not the truth because mine is a 2007 and it clearly doesn-€™t have child locks. Then they later proceeded to tell me I should just sell my vehicle. I was so upset because if one of my kids would have fallen out and something happened I would do everything in my power to make sure they were held accountable and file a lawsuit against them. Yes The vehicle is available to inspect. My kids safety was at risk and then me braking and pulling off the highway in panic mode could have caused an accident.it-€™s been reported to gm and also local dealers. There was no warning just when it happened scared me so bad because my kids are in my back seat. The photos I uploaded are of the transcribed voicemails and I-€™m willing to also submit the voicemails from gm as well.

On 3/13/2020 my wife was driving our 2007 Hummer H3 when the engine compartment and dash area caught on fire. The blower motor connector module had been replaced recently as part of a safety recall. The vehicle was in motion and she had just made a left turn. Although the part had been replaced, I still believe that this recall issue was the cause of said fire. The fire department called it an electrical issue. There was no warning at all. This was traumatic for my wife she had to jump out of the vehicle and had a miscarriage.

With no warning lights or signs, H3 wouldn't accelerate while pressing the gas.

Oil light comes on when idle. Truck loses pressure. No dealership solution.

Passlock issues not allowing the vehicle to start. Wait 10min with multiple attempts.

I don't know why I have to wait 10 min.before the truck will start this is crazy and no one wants to fix the issue.I have had it to 2 different dealers and they say its all the Hummer H3S that this problem is in the computer and will cost me over $800 to fix thats crazy this should be put for recall not good business I have children that if theres an emergancy my Hummer wont start. Really GM get it together this happenes all the time and half the time I have to wait 20 to 30 min for it to start

I stopped at gas station for fuel. Vehicle would not start for approximately 10 minutes after fueling up. Then it started. Apparently this is a wide spread problem with the Hummer, as I have read a number of incidents reported on line with same issue.

Yesterday, January 9, 2018, the louvre on the front of my vehicle blew off while I was driving. It was subsequently run over by the vehicle behind me and broken. Lucky no one was hurt. In researching the replacement part, I came to learn that there was a recall issued to remedy the problem. I contacted Cadillac of dublin to replace/repair the louvre. They then informed me that the recall had been done at jeff wyler in ky. This is categorically untrue. Clearly, the recall was not done. There is absolutely no glue residue anywhere on my vehicle or the louvre. Moreover, had jeff wyler actually performed the recall, it failed. Miserably. I should not be responsible to pay for the part nor the replacement thereof. The information in the recall system needs to be corrected/updated/revised to accurately reflect that the recall was not done, so that I can actually have the situation corrected/required work performed.

About 2 years after I bougth car from dealer, the car cranks but wont start you have to wait 20 minutes and it starts today it left me stranded over 60 miles away, it has being doing this every few months, I saw a forum with hundreds of people having same problem and dealer says it doesent find anything that's what I was told two times at dealer, from the forum it seems to be a faulty passlock security problem or a faulty egnition switch on several years of Hummer, GM needs to recall this because is causing lots of expenses to a lot of people including

Radiator leak, dripping the coolant and its a design flaw. The plastic on the top of radiotr gets cracked and is a known issue to all having Hummer H3. This should be a become a recall as its very risky as there is high risk for engine to get fryed cause of no coolant.

Everything from: Electrical, air condition, stabilitrack system, which cost me over $600 still not working properly. Leakingsun roof censors, I was made to pay for that still dont work. I paid over $8,000, or more. When ever I brought my vechicle in, I was forced to for something else, my vechile only had about $22,000 miles. I was taking it to GMC/vera Cadillac 300 pembroke pines, fl 33025, ph:(954)362-9465, service manager Mr. Gustavo, edwin montoya. I have over 50 pages documents about fake repairs, my vechicle is wrost off now than before. It also has safty issues, mold/medw, ac overheating, airbag not working, etc. I am afraid for my safty.

Several times, while parked, the passlock security system will randomly disables the engine from starting. After waiting 10 minutes the system will allow the vehicle to start. This makes starting the vehicle in an emergency very unreliable and dangerous.

On several occasions I have noticed steady water drops dripping onto front passenger floor. I have taken it to the dealers and they "performed water test" with negative results. I decided to look at my vehicle in the rain and noticed that there was a steady stream of water seen flowing down my windshield on the right side. I raised the hood and saw that rain was flowing around and down into the air intake cover. I could actually see the rain flowing down there and then dripping from under my glove box area onto the floor. There is a lot of visible electrical stuff going on under there and this bothers me more than the wet damp odor that is now coming from my floor because it has been continuously wet over the past several weeks due to rain.

I have owned my Hummer H3 for approximately 8 years and during the last 4 to 5 years I have experienced a repetitive issue with the vehicle not starting and then after waiting 10 minutes and it starts with no issues. This of course has been happening more frequently now, becoming more and more of an annoyance/inconvenience. I have communicated this to GM and their answer is that it is not a recall and they sound somewhat surprised with the issue as if they are hearing it for the first time. I have gone online and have witnessed the numerous complaints from other Hummer customers. Some have spent thousands of dollars to achieve temporary or no resolution to this problem. I am hoping that my testimony to this issue will further corroborate/justify other complains already filed for the same problem and influence a corrective action response "recall" from GM.

I keep getting a code that states that my truck runs with a low engine temperature. Plus my truck has had a leak from some where around the lower windshield that is causing electrical problems and soaking wet floors! we had a mechanic look for the leak and try to fix this issue but was unable to find the problem and we were also told by a few dealership that they have seen a lot of H3 Hummer with the same problem! also we are having issues that causes the traction signal to come on regularly and it causes my truck to lock up. It has almost caused us to wreck several times! it's very scary to drive my Hummer! every time we have any of these problems we are always in motion and it's always on the highway when we are driving at higher speeds. It never seems to happen while driving around town!! this has been continuing going on ever since we purchased this vehicle in August 2014

3-4 months ago my A/C unit started making a loud noise with a burning smell when I would put my A/C switch on level 3 or 4. it would sound like if my A/C unit was going to blow up. The next day I received a recall letter from the Hummer company descriving the same symptoms my H3 A/C unit is having.I called the Hummer company and asked them how long is going to take for them to fix this problem they stated in a very rude manner that they will fix it when ever they get the part. This is the worst experience ever I. I asked them if it can take more than a year and they responded we do not know. I got very upset because its not fair that I spend a lot of my money to buy my H3 and if its a recall why they dont help me to fix my problem, I explain to them that the weather in Texas is very hot and I been without A/C since and they dont care. This is not fair please help me out. I dont even know what to do anymore, please advise. Help!!!!!!!!

Our 2007 H3 had cracked radiator with hose leaking coolant causing the overheating. We have never driven the vehicle off-roading and no warning light was displayed for this issue. Instead, we brought it in for a different issue with the fuel line and discovered the cracked radiator, which could have caused a bigger problem if it had gone undiscovered for longer period of time.
