i have an 05 duramax diesel and the speedo on the insturment panel is acting funny. it will stick and then catch up!! and when i stop at a light it says that i am doing 15 to 20 miles and then go down to zero!!! just wondering if anyone else w an 05 or anybody has the same problem w there speedomter!!!

Please do a search on speedometer and check off the Search titles box. You'll see a ton of posts already that will help you.

Geezz, Yaz. You could of at least said use #10 in Rttoys's sig.:D

no need for all of that guys!!! i just got off the phone w the people at gm and they contacted my local stealer!!! they told my stealer about the problems and they said that they would repalce the intsturment panel for free thanks to GM!!! Wow and my truck is an 05 and is not covered under that special coverage through gm on the 04 and 03 models!!!

They should, they know it's a problem, nothing changed till the new body style in '07

we have had several problems and there is a special policy on 03 and 04 vehicles.
