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.

After reading all if these complaints I decided to write mine. Probably about a little over a year ago the first thing that started was my tpm sensor would come on and then go off I took it to the tire store and they said this could be going bad ok well then it stopped , next I got into my vehicle from grocery shopping and my car would not start in the hot summer in my vehicle ( thank god my 2 young kids weren't with me) after several attempts it finally started, this happens a lot more then once until one day when it was freezing cold outside in wonderful wyoming my key would not come out of the ignition, I had to unplug my battery until I could take it to the shop ! Then after I get my car back a few days later my blower to my heater quit working for a few minutes and then I smelled a burning smell, I called the repair shop again to take it back and there was a charred wire and they had to replace what was being recalled.( I received the 1st letter about 6 months later) , which I still haven't received a 2nd letter! Now I'm starting to have a issue of my car dying when I'm slowing down to stop at a stop sign or to turn!!! I happened to get on her and read all the complaints and nothing has been done!!! I have 2 small children and this is absolutely disturbing, I am really regretting not getting rid of this vehicle last year!! I beg that you all please look into these, before someone dies or anything else!! ( it shouldn't even get to that point). I had about 70,000 miles when this all started and noe I have 84,999. My MPH was 0-30 !!!

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!!!!!!!!

Today I am reaching out to you for your help. This letter is in reference to the gm recall on the hummer h3 A/C module resistor that was issued in july of 2015. My wife and I have reached out to gm on multiple occasions with no resolution in site. I ask that the federal safety agency demand gm establish a timeline for the completion of a corrected part and that gm provide an adequate alternative option to gm customers faced with this issue until the part is available. My concern is over my well-being as well as my families. On monday august 31, 2015, I was driving home from work when I noticed a burning smell coming from underneath my glove box. After I pulled over and examined closer I could see the issue was from the A/C module resister that was recently recalled. The resister had burned through part of the harness attachment. Upon reaching out to gm, they stated I only had two courses of action: 1) to replace the part with another faulty part (which I would have to pay for) and hope that the part does not short / catch fire before they are able to come out with the corrected part (which would be free). 2) wait for a corrected part to become available. The main issues with the second option are that gm has no timeline for the completion/availability of the corrected AC module resistor (customer service said anywhere from 1 month to multiple years). This would leave the customer (without heat or A/C) for an extended period of time. My current work commute totals 2 hours every day. Where I live this becomes problematic due to severe summer / winter climates (as I write to you there are heat warnings in effect). Gm has known about this issue since 2009, yet they failed to act. Now the consumer is forced to face the consequences of their ill planning and neglect while gm continues to act inept. Please help gm realize that gm customer lives matter.
