Excessive ethanol causes standard HSBN polymers to almost melt so GM won't have a problem seeing what the actual problem was that caused the damage when your injectors are plugged up with rubber and the fuel lines fall apart in their hands as well as a fuel pump that has no seals left.

My dad was running a stock car in the early 80s and was having troubles with clogging fuel lines. It looked like someone had squirted silicone sealant into his gas tank. They diagnosed it as the new ethanol blends that were first showing up. I imagine you would get the same effect with E85.
