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 !!!
