At first my speedometer would 'tick' and that led to it jumping around. It sticks in various places, sometimes down to the right far off of the gauge itself. My tachometer does the same thing. It has been this way for a while now, I just can't want to fork over $600 to get it fixed. I heard that GM infact has and unpublished bulletin under their goodwill program to fix it - can this be made to be a published bulletin?

I have a problem with my speedometer. Every day after driving it for 30 +/- miles the speedometer stops. Sometimes at 50 sometimes at 0 mph. Once I begin to drive it will sometimes go from 50 to 100 or it will stay where it stopped. This started about 18 months ago but it only happened once every couple months. Now it happens daily. I have learned that after leaving it set for a few hours I start it up, put it into drive and turn it off. With the gearshift in drive I try starting it and each time I turn the key the speedometer goes from 50 to 40 to 30 and then back to 0. once at zero I start the truck and the speedometer will be accurate for at least 30+/- miles.

While driving my GMC Sierra the speedometer reading is grossly and obviously inaccurate. I took it to my mechanic and he says that GM parts will cost approximately $600 and that this is an extremely common problem that the dealer shop says he sees several times a week on this model of pickup. Using my gps for speed monitoring since I don't want to pay GM an exorbitant repair fee for something they aren't standing behind.
