Well, expensive is a relative term. Ususally this issue is the tank sender, but of course you need to test it. The problem is now most tank units also have an expensive fuel pump as part of it and both get changed. This involves tank removal in most cases. This issue is not limited to your type of vehicle.

you need a new cluster if you have less than 75,000 miles check with the dealer gmc issued a recall for that, if your over that look on ebay for a replace or repair service

You can just replace the gas cap...However about the fuel guage fluctuates back and forth...thats due to the sending unit, which is located on the fuel pump itself

GM had a problem with the fuel sending unit cards inside the fuel tank,If you replace that you should be good to go.

The sending unit in your tank is bad replace it.

Is it ALL of the gauges? My wife's 2005 Envoy Denali had a problem with the gas gauge sending unit (in the tank) that made the gauge act erratic. Also, the check engine light would stay on alot. If it is all the gauges, then it may well be the dash unit. Hope that helps some.

U must replace the fuel gauge sending unit to correct the problem with your gauge, the sender is located inside the fuel tank, the tank must be removed to replace the sender.

There is a Sending Unit for the Gas Guage Under the Dash I Believe. It usually Runs about $750.00 Just for the Unit. I agree with you!

a fuel sending unit seems to be the most popular solution. the part is about $40. I think the labor is what's going to kill you.
