1 Fuel Hoses Lines/piping And Fittings problem

Failure Date: 09/04/2011

I noticed a strong odor of gas coming from under the truck. I only noticed the fuel leaking when the truck was on a downhill grade. I climbed under the truck to see where it was coming from. It turns out that the fuel leak is coming from the return line on the frame under where the fuel filter is attached. That section of the fuel line is totally corroted and fuel is slowly dripping from it. I am taking it to my mechanic tomorrow for repair. The brake line right above the fuel line is also severly corroted. Gm really needs to recall and fix these issues due to these corroted fuel and brake lines. I will never buy another gm product again.

2 Fuel Hoses Lines/piping And Fittings problem

Failure Date: 09/28/2010

Severe corrosion of the brake lines became apparent during a sudden application of the brakes which caused multiple brake lines to rupture and leave the vehicle with no brakes since a line from the master cylinder to the abs unit front left input and the abs to the rear t line blew simultaneously. When removing the damaged brake lines they literally crumbled to pieces due to corrosion. During the repair to the brake lines severe corrosion was noted on the fuel lines also.
