My grand prix recently started to display a message stating reduced engine power. It has been happening randomly for the past week. It only happens as I am driving the car. The car slows dramatically, and does not accelerate at all. As I was driving yesterday, I was merging into traffic where the speed limit is 45 MPH, I had more than enough room to merge into traffic, the reduced engine power message displayed and the car would not accelerate. The traffic quickly caught up to me and I was almost hit due to the car not accelerating. I am curious after looking into this matter and finding so many complaints about the same issue, how many complaints need to be filed, or how many deaths need to occur before something is done? I am now scared to drive my own car.

We purchased the vehicle from a dealer inthe tri-cities area of eastern washington in 2010. The car may have been a lease return. However one of the selling points with the car was the remote starter option. The weather in eastern oregon where we lived at the time was a life saver. However when the battery went dead and replaced at the dealer the remote start quit working. Not only quit working but it even disappeared from the vehicle dic. The remote start is even listed in the vehicle owners manual. But the dealer in medford, oregon, air port chevy/caddi cant seem to figure it out. We have had the vehicle at the dealers in medford 6 times. Even during the recall for the key fob issues and ignition switch fires, the dealers also looked into the darn failure of the remote start but they never did fix anything nor do they have any ideas as to get the thing fixed.
