Fuel Pump problem #1

While driving at 75 mph in cruise control mode vehicle stalled. Consumer proceeded to pull off the road. This failure occurred 4 times, simultaneously while in route to the dealership. The dealership indicated that the fuel pump needed to be replaced. The fuel pump was replaced, but the failure recurred.

Fuel Hoses Lines/piping And Fittings problem #2

I was leaving my driveway and completely lost all brakes and could not stop. I had to slam on the parking brake to stop. A brake line blew. All the brake lines and fuel lines are completely rotted. This vehicle isn't even 10 years old yet. The fuel line and brake lines are a major safety issue. This truck is a 2500 and I use it for towing trailers if that brake line went while towing it would have been a major accident. The entire underneath of this truck is so rusted the frame brake line and fuel lines are terrible. Someone is going to get killed from gm's cheap steel.
