The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault. The warranty has been extended on some of these units to 7 years or 70,000 miles.Google+

i had the same problem and found a guy that for about a 150.00 he pulled the dash and replaced all the gauge units - seems the original gauges fuel and speed etc have a small motor unit that drys out n cracks so it doesnt work first sometimes then more n more - after 2 failed speed n oil i looked into it and now it works great again - was a real easy fix if you know how to remove the solder right n solder em back on also finding teh little motor part would be a hasle - or you can have teh dealer just replace the whole unit instead for 400-600 , but pay a guy to do it lots less stress n time ( took him about 30 min to replace all 6 )
My panel cluster gauge needle function is shot to hell. Nothing works. Took it to the dealer and will have to keep my car for 2 days, will replace the panle but I have to pay 300.00 for labor. I called GM and found out absolutely nothing. Guess I will have to pay.

I was driving home from a trip and about 1 hour into the drive, the speedometer just starting reading the wrong speed. I was on the highway at 65 mph and the next time I looked down...without slowing down...it read 20mph. It stayed that way...until I stopped for gas. After I stopped the car and turned it off to pump gas, it started working again when I got back on the road. It has only happened this once so I haven't looked into fixing it yet.

Speedometer stopped working. Fixed cluster by replacing server inside cluster. Ordered repair parts on internet.

First the oil pressure gauge quit then the whole entire instrument stopped.
The speedometer became uncalibrated and I use my GPS to go the correct speed. Yes this was ghetto but free. The problem self corrected itself about a week later. Then about two weeks later ALL the gauges fuel, battery etc. went out. New instrument panel 468.00 plus labor and a one year warranty or 12,000 miles, done at my local Chevy dealer. Not sure why they can't guarantee their work past a year. Leaves me with little faith in the workmanship just saying.

Speedometer stopped functioning, most likely a bad stepper motor based on how it is acting. You can get a new instrument cluster for ~$190 and install yourself or go to the dealer who want $595 for the cluster without installation. You can replace the motor itself but it is much more work than just swapping the cluster. Plus my wife has a 2005 which did the same thing and then all the other gauges quit working as well and I replaced her's at that time.

Got a letter thought it was a recall didn't read small print. It was acting up some at that time. My husband had cancer going through treatment and I didnt have time to be without a car. I called dealership they said it should be acting erractic and to bring it in then. Ha I did by then to many miles and they wanted too Many $$$$$ ordered the part on line and installed myself. I will know better next time.
Speedometer indicates incorrect speed and records 10 when the vehicle is stopped.
Sometimes it is ok, other times i could be going 65 and it will indicate 40mph.
I sent my instrument cluster to firstname.lastname@example.org. $247 and it was repaired within a week and
saved me $600. It will also take care of your gage problems. I highly recommend it.
