I have been buying (2) 1500 silverado's every year for the past 11 years with the awsome 6.2L. They are used as business trucks for work in the field in remote locations. The people that are using these trucks are using them as mobile offices. This feature of shutting off when ever it wants is for the birds. I realize that this was installed as a safety feature but it is a big pain in the butt! If their are that many dumb people out there that they can't tell when their vehicle is running or not, maybe the push button is to advanced for them and we need to return to a key system. I hate that I am being forced to look for other options for trucks and as of this morning a Dodge 1500 Limited got the nod. Im going to miss the awsome trucks chevrolet makes but as the cold is coming and I can't have people in freezing conditions with trucks that dictate to them when they will work! If your looking for a daily commuter and not a work truck look at Chevrolet!!! Such a shame!!!
