1 Fuel Hoses Lines/piping And Fittings problem of the 2004 GMC Sierra

Failure Date: 08/08/2012

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.

3 Fuel Hoses Lines/piping And Fittings problem of the 1999 GMC Sierra

Failure Date: 10/21/2009

I was returning from hunting trip ,and when I got off I-75 freeway to go to my home traffic signal ahead was red and pedal went to floor. Fortunately,the light switched to green and I was able to manuever to not collide with car stopped ahead. I nursed it home via back streets at very low speed and to the repair shop the next morning. Mechanic replaced brake line. The fuel line was rusted out at the fuel filter and discovered while other maintainance was being performed. The undercarriage is extremely rusted and I am concerned about pulling my travel trailer due to rusty condition of things. Rocker panels are rusted out as well as rear fender wells. Surely gm can control corrosion better than they are doing. Someone is going to be hurt or killed due to these vehicles rusting so badly.
