2003 GMC Envoy Owner Comments

problem #3

I have 03 GMC Envoy that I take very good care of. I have been smelling gas lately and not seen any gas leaking. The gas odor gradually has been getting stronger and stronger. Eventually I was able to tell that there is a gas leak, but is only leaking a small amount while the truck is running. Now my Envoy reeks of gasoline all the time outside and sometimes inside when the heat is on and idling. Seems the gas pools on an indent on top of the gas tank and when I pull into my driveway(down a steep hill and sharp turn) it all pours out. Seems that everyone is having the same type problems. Seems to me this is a bad design on GM's behalf.......maybe they will step up to the plate and fix this obvious defect. I wonder if they still produce them like this? I can only assume that this affects so many other models. Yikes! that's a lot of people who are in danger or got stuck with a lofty repair bill.

Vehicle: 2003 GMC Envoy failure: Speedometor and fuel gauge stopped working. The dealer states this is a very common problem and GM known about this defect but refuse to do anything about it. The instrument cluster needs to be replaced, approx cost of repair is $500 (part & labor). I am very uncomfortable to drive not knowing how fast I am going especially when drive with my baby in GMC Envoy.
