One by one things have been going out and not working. First the car would not start all the time with the key, then the A/C stoped working, next was the fuel pump, then the injectors. I checked everything it could be. I was driving with my kids down the highway when my car just died lost power steering so it was hard to get off the road fast. I got it started and was driving and it did it again. I was able to finally get it home when it would not start again. After some research online found out this car has issues with the fuse box itself under the hood. I opened it up just to find the wording that connected the pins was broken in numerous places and had started to burn up in the box.

What owners say
Vehicle's reduced engine power light comes on, and vehicle loses power in dangerous places. Lost of problems consist of several parts having to do with acceleration. This problem happened suddenly, andnis a danger to himan safety because of it happening several times including o n the highway.
The transmission cooling lines corroded and caused a transmission fluid leak. The engine rpms increased and the vehicle lost power while going down interstate 86. When the fluid leaked out of the transmission cooling lines, it sprayed all over the exhaust pipes, which caused a severe fire hazard. Due to the loss of transmission fluid, it cased significant damage to the transmission internals.
My vehicle started randomly shutting off while driving. Loss of power to everything but the brakes. Luckily I was only going 10-15mph each time this happened. With the recent recall in gm vehicles regarding the ignition switch I thought it would be a good idea to switch this part out first. Fixed the problem immediately. I would like to be reimbursed my cost for part and labor. I can't believe as many known problems the trailblazer has with this that it has yet to be added to the recall list.

I was driving the truck and the fuel gauge was reading that there was gas in the tank. The vehicle died causing loss of power steering and power brakes. I was able to pull the truck to the side of the road with great effort. Had my wife or teenage daughter been driving the outcome might had been very different.after filling the gas tank the gauge went to e and never worked properly afterwards.

Erratic fuel gauge for couple of days and abrupt engine power loss, fuel gauge stayed below empty mark even after full fill up.
As of today, my reduced engine power light came on and there appears to be an issue with the electronic throttle control system. When I turned the car off, and then restarted it, the problem went away, but then a few minutes later, came on again, and the car would not accelerate. This is a major safety concern as the problem occurred crossing an intersection. Luckily there was no oncoming traffic, or it could have been very serious.
Our 2002 chevrolet trailblazer loses power and the trouble lights flash including the service light and reduced power light come on. I have changed the 02 sensor, flushed the transmission, replaced spark plugs and had the emission system checked all to no avail. Our mechanic cannot isolate the problem and all things we have tried has failed. We have reset the computer several times to no avail. This is a problem and safety issue. We have had no help from gm.
