One problem related to car will not accelerate has been reported for the 2006 Chevrolet Trailblazer. The most recently reported issues are listed below.
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.
