Trailblazer 6-cyl

  • 66,000 miles
I have been hearing a clicking noise and my car had begun sounding like a jet engine taking off for the last 3 days - very noisy. I took it to pep boys where I was told that it is normal for the Trailblazer to begin making this noise shortly after 60K miles. I was told the serpentine belt needed to be replaced, tensioner pulley and the idler pulley. I had the new parts installed. None of my warning lights came on the dashboard so I assumed was well as there was no other indication that something was wrong. Driving my car within 24 hours of being fixed, the fan clutch seized and my water pump burst causing car to overheat in the middle of an intersection where my car then stalled putting me and my children at risk for injury. The car almost caught on fire it was smoking severely. Someone helped me move my car out of the busy intersection and I called my husband and a tow truck to come get the car. When I got home and looked up the problems again on the dealer website, I found hundreds of forums where the fan clutch has been mentioned and the water pump too. A fan clutch according to the mechanics I surveyed stated they should last at least 100K or more. This has been brought to GM and they ignore it. It is a safety issue. Additionally, my speedometer hasn't worked for at least a year and when I called Chevy they wanted to charge me $700 to replace it when it is not my issues. I didn't cause it. Not knowing what speed you are going is definitely a safety hazard and can cause accidents or tickets.I am attaching a forum (this is just one of hundreds I found online)www.edmunds.com/Chevrolet/Trailblazer/2004/consumer-discussions.html where people are having the same safety issues I am and GM has ignored them. My car could have caught on fire today and I had my 4 yr old daughter with me. Not a position I ever want to be in. Please issue a recall.

I own a 2005 Chevy Trailblazer that is experiencing very sluggish acceleration, transmission is not shifting smoothly, and runs very loudly. I have researched this problem and found hundreds of complaints with other owners of this same year, make and model.

After doing some research I am encountering a problem that seems to be out there a lot. I have a 2005 Trailblazer and my forward gear stopped working at 80K miles. I think is a much too new car to encounter a transmission failure. There is obviously a problem when I have read pages and pages of this same issue. GM has to step in and tell me something my dealer estimate this to cost me a min. $3,200 in this economy or any that is a large expense to encounter with no warning or previous problems. I hope the GM will have some answers and do the right thing! this happened to me on the van wyke expressway in rush hour many of us could have been hurt or killed! thank you

Had to have transmission replaced (a whole other sick story:( ). when I got my truck back, second day on the freeway, the speedometer started to climb even though I was staying with the flow of traffic. I twent around to the 100S. When I got home it spun straight down not stopping at the zero like it normally did. Took it back to mechanic at least twice maybe 3 times, he did something that fixed it for a few days, but then it would mess up again. As it is right now, it is parked but saying it's at 100+ mph. Reading other peoples same problem, it will cost too much for me to pay the dealer to fix. I have even gotten a speeding ticket because of this (my first in 20 years!)!!!

The transmission shifted hard from first to second gear. The transmission shifted so hard that it almost jerked the steering wheel out of the consumers hands. The second concern was when the consumer had to place the rear seat down to place items in the back, it required that the front seat be moved forward and would not go all the way back again. The last concern was that the vehicle could not use tire chains due to the fact that there wasn't enough clearance and the consumer was informed to use another traction device.
