2003 Envoy Speedometer Sticking Issues

Hello

I have a 2003 Envoy SLT and lately my speedometer has been "sticking" I will be on the highway doing at least 65 MPH and I look down and my speedometer says I am doing 20 to 30 MPH. All of the other displays are fine.

I have noticed than when I drive the needle on the speedometer seems to "stick at certain points" It almost looks like it needs to be lubed (i dont know if thats possible) or it looks like it gets caught on something....It only happens when I am increasing speed. Decreasing speed seems to always be smooth.

The needle always returns to zero when I stop the truck.

Any thoughts or help would be appreciated

Thank You

Internal in the speedo head.

I too have problems with the speedo it sticks at 65 but doesn't reset and now it's stuck past 120. GMC should fix this no?

Welcome to AF, I don't think anyone here can answer a question based on whether a car is still under warrantee, it has 3/36 coverage.
