I bought my Colorado in April looking for fuel economy the salesman were very good. But this truck is full of probiems. Just to start the fuel economy, it gives only 19 miles per gallon on the expway. This traveling 200 miles north with the wind going the same direction. The brakes do not work fine after the truck being parked for more than 4 hours. It does not have any power at all. I feel this is not I reliable for family, truck. The worst part for me is the poor shop service the place I bought my truck has. The personnel checked the truck in less than 5 minutes and told me that the computer did not registered anything wrong and in regard to the brakes the manager said " it is brakes dust.
