| Service engine soon light was on after completing a diagnostic test at a local dealer they said the malfunction was the secondary air injection(air pump) code p0410. they said the reason these go out is because of an engineering defect and the way they routed the hoses instead of air flowing through it causes water to accumulate therefore making the motor in the air pump to go bad. so while changing out this bad air pump there was so much water that had accumulated it actually caused the light to blow which could have caused the mechanic to be electrocuted! *tr | |||

| I was traveling on the highway when i herd a rattling sound coming from the engine, got off the highway and pull into a station. call the tow company to tow it to my mechanic he said the water pump bearings broke and the fan stop turning since both are connected together, he said the engine might be damage possible due to overheating. there was no warning of over heating on the gage, water did not leak from the pump. i call gm and they told me to tow it to the dealer for diagnose and they were consider my claim after the diagnose check; they knew my warranty just expired in july. i told them there was know warning of any kind everything was find water pump bearings just broke along with the fan clutch this sample problem cause the whole engine to go bad. if there is going to be a problem with bearings broken on the water pump there should be a warning of this potential problem. right know i need help to get my truck fix gm denied my case to fix the engine. i believe gm knows there is a problem with these water pumps and serious damage it can cause if they fail. *tr | |||

| We have had a problem with our service engine light coming on within the past 2 weeks in our 2004 trailblazer. after getting it diagnosed it is being caused by the fan speed being too high. after doing some research this vehicle has had numerous repairs for the same issue. why has gm not warranted this!? we have gotten crappy service from the dealership and while our vehicle is out of warranty now it is paid for our we would have gotten rid of it already. *tr | |||

| Our 2004 chevrolet trailblazer with approx 40,000 miles caught fire while driving approximately 40 mph. we noted smoke behind the car and before we could pull over other drivers were yelling to us that the car was on fire. we immediately got to side of road, turned off engine and a large fire was coming from the hood. a good samaritan ran up with a fire extinguisher and put out the fire that was approx 4 feet high from the hood. all passengers safely exited the car as soon as stopping and due to the fire being extinguished quickly no other damage was done. this vehicle was running fine with no recent issues or service on the vehicle prior to this event. we have never had the car serviced by anyone other then chevrolet dealerships. we were informed by the tow truck company that they have many 2004 chevy trailblazers towed that have caught fire. i have seen similar experiences described online but have not found if there is a technical service bulletin related to this. *tr | |||

| After coming to a stop the 2004 chevrolet trailblazer ext stalled. i brought it to the santa maria home motors twice. the first time they addressed the problem with the 30,000 mile service and said see if it happens again. the trailblazer stalled again so they reprogramed the computer and charged me $85 to do this. today my wife was driving the trailblazer and it stalled again. like i have told the service agent at home motors i wa s afraid that this will happen when my wife and children were crossing the train track, and they could be killed by an oncoming train. i will bring the trailblazer back to the dealer tomorrow. *ak | |||

| Major electrical problems inside the vehicle. i have owned it less than a year.the vehicle has been in the shop twice in the past two weeks. exiting the freeway the i had a complete power failure. the vehicle completely stopped and locked up and there was a semi truck behind me! my vehicle was moving and in drive when this happened. i had two of my toddlers in the car with me! the vehicle was taken into a local dealer and unfortunately they could not find anything wrong with it. apparently, when the vehicle is restarted it erases the codes in the engine as to what caused the problem. well, it happened to me again this evening. same problem. this will be my 5th time of bringing this vehicle in for electrical problems in less than a year. i only have 9400 miles on the vehicle and bought it brand new. i do not feel safe driving this vehicle with my 5 children as passengers. is there a way gm can get me a better running vehicle? i paid a lot for this vehicle and am very unsatisfied with it's performace. there always seems to be something wrong with it. the connell chevrolet service here in killeen has been very helpful. i feel sorry for them because they did not sell me this vehicle but they are the ones nice enough to try and fix the multiple problems.*ak | |||

| I purchased a used 2004 chevy trailblazer in february 08. it only had 23,000 miles on it. with in the first 2 weeks i had it my gauges started going crazy. they were jumping around all over the place. i took it back to the dealer to have it fixed and they tried to charge me. fortunately i must have complained enough and to the right person because it was replaced at no charge to my self. i now am having major problems with it stalling and trying to stall. after searching the internet i see that i am not alone there are hundreds of complaints about this problem. everyday upon start up it idles very rough and it tries to stall for a good 10 minutes. if i don't let it sit and idle before i drive it tends to stall. my check engine light will flicker at least once a day and every few days my reduced engine power light will flicker. i do not feel safe anymore. what if i am traveling and my car stalls and i lose control and from reading the other complaints i am at risk for my air bags not deploying. if it is a problem with the pcm, i don't have the money to fix it!!!!! why should i have too? i see that i am not alone with this problem. why is their nothing being done about it? why should us as consumer already paying enough for these vehicles be responsible for their mistakes? *tr | |||
