I bought my 2005 Trailblazer the same year with 19+k miles. I started having it stall on me around 30k miles. I took it to hayward, CA chevy dealership because it was still under warranty. They said that they found nothing. I took in again because the engine light came up and they said the problem was the light only but, that's the light that would flash when it stalls. I took the car back in several times for the same situation. At the time, I had 2 boys. . . . . 8yrs and 6yrs and this started too become unreliable because I was putting them at risk and not only that, I would stall and then take a few minutes to start again. I've been told that maybe it stalls because the engine was not warm but I know that it can't be it because a few times I was on long road trips and the engine would stall on and off. This has been an ongoing problem since 06 and it's a horrible risk because it's stalls while driving. My kids and I can get hit from behind. I don't know who else to repost this too. I bought another car 5/07 because this vehicle is not reliable but use it when I have to and up to this day, it still stalls.

Subject:reduced power problem with Trailblazer
comments: I have a two year old chevy Trailblazer that has on three occasions had a dramatic loss of power and a reduced engine power light comes on and loses all acceleration. Twice this happened while I was on the highway, and I feared for my safety and the safety of my toddler, as my car slowed from 65 mph to 40 mph in a matter of seconds, and would not accelerate. According to the dealership, there is a problem with an electronic sensor to the accelerator. I have tried to raise this with Chevrolet customer service, who blatantly disregarded my safety concerns and told me that my concerns would go no further up than the customer service desk level and they could offer me no assistance. Based on my research, this is a documented manufacturing defect, however, gm refuses to recall any cars and claims that the bulletin documenting the problem only serves to assist dealers in the repair. I am concerned for the safety of all Trailblazer owners, and believe that chevy and gm need to be investigated for ignoring this dangerous safety issue. From NHTSA web site.
