My driver side seat heated seat short circuited and looks like it caught on fire briefly. My head lamp module went bad and is recalled but no remedy has been solved, dealership replaced at my expense but I cannot get reimbursement for repair due to remedy not yet available. Recall date was nov 25th 2015 am I suppose to drive without lights for 13 months. Since I took it too an authorized dealer and they fixed it why cant I get my money? Picture is from the internet but is actually the same as mine. I do have the defected seat element at my home.

As I was driving on the highway, my doors unlocked and locked several times over a period of 30 minutes. I then heard loud chirps from stereo speakers and then the smell of burning plastic. At this point I lost all window controls and audio(door chimes, radio and onstar). To this date I have not been able to use radio or driver side window controls but still notice a smell of melting rubber or plastic. I have two children with autism and I do not feel safe taking it on family outings.

This vehicle had been parked in the driveway from 7:45 pm, (august 10, 2011). I was awakened at approx. 3:55 am on 8-10-2011 by hearing a muffled boom. At 4:00 am (aug. 11, 2011) I heard a loud bang type noise. I immediately got up and went to investigate. I went outside and found my 2004 trailblazer (ext) on fire from the engine bay and just beginning to flame inside the vehicle's passenger compartment at the dashboard..it only took minutes before the vehicle was fully involved. The fire began in the engine bay. The fire marshall report is still pending and I was informed it would take 6 to 8 weeks before it was available. Approx. Two to three months prior, I took the vehicle to a repair garage to fix the low beam headlights (they had failed and changing the bulbs was no help. It turned out that it was a failed relay, which was replaced. It was a couple of weeks later that I had to replace the vehicle's battery as it had gone dead and would not take a charge. The old battery was about three years old. There were no other battery/headlight issues after these repairs. No tools or other parts were dropped into the engine bay, or left in the bay. I was an aircraft mechanic and old habits of keeping rack of my tools never die and all tools used were accounted for. The roads were dry where it was driven there was no rain at the house all night. I reported this to chevrolet that day. As a result of the fire, the eaves of the house over the garage caught fire, my wife, son and myself had minor carbon monoxide poisoning, my work truck was damaged by the heat of the fire, so I cannot work (self employed) until I get a replacement (no rental company will let me use a truck to work from as I need to carry large quantities of chlorine in my pressure cleaning business. There have been no other problems of this kind before with this vehicle.

I have a 2003 chevy trailblazer ext the fuel pump module has started to corrode, I knew something was wrong because of the strong odor of gasoline inside the vehicle and further investigation showed a leak of gas also.this is in addition to our gas gauge not working for the last 3 years. Upon talking to multiple rep's, gm claims they sent out letters in 2007 alerting the consumer to a potential problem. I am the second owner of this vehicle. I purchased this vehicle in september 2005. Gm stated that letters do get lost in the mail, when I stated we were not made aware of this situation. I was never informed of this potential hazard waiting to happen. Gm claims the service bulletin had parameters of 10 years or a 120, 000 miles which ever comes first. I have been in contact with the rep several times, and have not been successful. I do have 149,000 plus miles on this vehicle. I took the truck to the local dealership, they were claiming nothing has ever been documented on this type of vehicle. This is when I did my own research and found the service bulletin as mentioned above and the complaints of this same problem all through the internet blogs. It seems we are not getting anywhere and would appreciate some condsideration from gm and taking part of the responsibility for this problem. We had our children in this car when the gas was leaking out, what if it would have caught on fire? I would like to contact our regional representative for gm.

The service engine light was coming on and we had diagnostic done and was told that it was the gas cap. We replaced several time. Everytime I drove or rode in my vehicle I smelled gas and I would get a horrible headache. My husband took my vehicle to get an emission test done we were told the fuel tank was cracked at the neck and leaking gas. We had it repaired nov 6, 2009 after we had been told of this. The shop that repaired my vehicle said they were shocked it had not caught on fire. There was evidence this had been going on for a while. Probably when we were told the gas cap was loose is when it started, and that had been over a year before.

While driving on a interstate at highway speed. My vehicle had a sudden decrease in forward momentum. The engine RPM's increased dramatically and the vehicle had unpredictable surges and loss of ability to maintain speed. After driving down the berm to the interstate exit, I noted a burning smell. The smell was that of transmission fluid that had leaked out from a corroded transmission cooling line.

I started to lose the high speeds on the fan blower. In checking the internet I found this is a common problem for g.m. The problem is the blower motor resistor. When I went to replace this part I found that the whole wiring harness had been burnt to. It got so hot that it melted everything. The fuse for this did not even blow. This could have set the truck on fire. It is funny how the parts to fix this has much thicker wire. The parts in total was around $118. Thanks to a friend I had no labor cost. If I would of taken it to a g.m. Dealer for sure they would of wanted over $300. G.m. Knows they have a problem and are doing nothing about it. I feel this is a serious matter as it could of set the truck on fire.
