Hi, everyone. I've been driving a 2008 Silverado 2500 since April of this year. One thing that bugs me about it is that the cruise control does not start to correct until the vehicle speed varies by more than +/- 3mph from the setpoint. This is the first vehicle I have driven that has such a sloppy cruise control. I beleive it to be a safety hazard because it slows down so much when going up the slightest incline, making the traffic behind you have to brake and go around. By the time they get next to you, the Sileverado starts to speed up again, making it look like I'm trying to block the other motorist from getting back into the lane. Is there some programming the dealer can do to get some of the slop out of the cruise control? Thanks.
