I know there has been other posts on this my speedometer does not move smooth it started it about a month ago i have not had time to take it into the dealer with xmas and all wondering if there are any updates on this problem and who else has had this problem.

For these complaints (which usually is at lower speeds) the fix is to replace instrument cluster.

I take my car in tomorow morning to get the speedo looked at i hope they replace it not tell me theres nothing wrong like they have done before with other things

Mine has been doing that as well. Sort of jumps in increments of 2-4 Mph.

My G6 developed a speedometer problem last week. At speeds above 75mph the needle would suddenly drop from 75 to 40 and then recover. Took it to the dealer this morning and while they couldn't duplicate the problem, they "re-programmed" the instrument cluster. I took it back out an went about 10 miles at 75mph and it seemed OK. Will have to watch it.

Hmm, interesting because I don't think the instrument cluster can be reprogrammed

I know I'm behind here...I have just noticed the same problem..well not just but a while ago...I 've been thinking about taking it in but my work isn't in the same city as the dealership anymore and I don't trust other dealers around. I'll put this on my list of things to be looked at...along with the engine not turning over properly.

Speedometer issue

Update - Problem happened again and this time I rode with the dealer's technician and this time we were able to duplicate the problem. He thinks it's a wiring issue. I am going to take it in next week and leave it.

:banana: I posted on hear a year ago about my speedo issues i got so sick of it now i just can tell how fast i am going without looking most of the time mine would be 5mph off sum times or it would just not move, my favroite is the 2min dance on start up before it decided to start workin LOL.
But the kicker is everytime i get an oil change or something there i will tell them to check it out and it is always working perfectly when i am in there and everyone thinks i am CRAZY!

Hmm I've never heard of this problem before. Let us know what it was.

7/12/06 The car has been in the shop for almost a week. They replaced the speed sensor but problem was still there. They just called to tell me that the GM techical folks think that there is a seal leaking in the transmission that is causing the gear that sends the signal to the speedometer to slip at speeds of 75 mph and above. They now have the transmission apart. If that doesn't fix it, they are going to replace the transmission. I hope the cure is not worse than the problem.
