Took 2003 silverado in to dealership to have computer updated, ever since then I have been experiencing problems with the speedometer. It is erratic, and displays speeds much higher than actual speed. I am able to turn ignition on and off to get it to reset back to zero, but that is not always easy when traveling down the freeway.
