Five problems related to check engine light on have been reported for the 2003 Chevrolet Trailblazer. The most recently reported issues are listed below.
My 2003 chevy Trailblazer check engine light comes on accompanied by the low engnie power light. The vehicle goes into limp mode. This is a safety feature that allows the computer to protect the engine from any damage should something go wrong. The only problem is that there is nothing wrong. This happens multiple times a day (6-8). Changing sensors doesn't fix it. I believe it to be a problem with the 2003 chevy Trailblazer computer. I have read many forums with hundreds of people that have this same problem. Please look into it before it causes an accident or makes an emergency situation a fatal one.

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.
