Noticed fuel smell after exiting vehicle. Looked under vehicle to see fuel dripping on the ground directly below the fuel cell. Further investigation revealed the fuel lines were severely corroded or rusted to the point of failure. Also noticed the brake lines were also severely rusted. GM has sacrificed safety in place of cheap parts and materials. This is a major defect and a serious matter that needs to be rectified. Someone will die with the brake and fuel line failures.

Another vehicle pulled out in front of me while I was towing my boat. When I hit the brakes the pedal went to the floor; I narrowly avoided a collision. A rusted brake line had ruptured. When replacing the brake line I discovered that all of the brake lines and fuel lines were severely rusted. We contacted GM; they set up an appointment at a local dealership to examine the truck. The dealer agreed that the lines and much of the chassis were rusted but would not do anything about it. When the truck was still under warranty I had complained to the dealer that the undercoating on the frame was falling off, and there was actually rust under the coating. They said this was not covered by the warranty. I have also had to replace all four brake rotors because they were so rusted they were falling apart. The rear rotors went at only 35000 miles.

Driving home down two lane road at 35 mph. Came to curve and slow traffic ahead. Went to apply brakes like normally, they failed. Pedal traveled all the way to floor with little to no stopping effects on vehicle. Vehicle is a 5 spd standard. I was able to down shift and apply park brake to slow vehicle. I was unable to stop completely and had to drive off the road into the road side ditch to avoid a collision with the stopped traffic. Once stopped I got out to check for damage. No cosmetic damage was sustained to the vehicle. I did see brake fluid dripping from under the truck on the driver side. Closer look revealed that the brake line had rust completely in half and bleed the brake system dry. Noticed that the other lines were in similar condition. They all seem to be severely rusted at the point where the brake lines is retained by a green plastic clip on the upper portion of the frame rail. Had vehicle towed home, replaced visible bad lines. Two months later brake section in rear of truck hid by undercoating failed as well. Thankfully was parked when it happened this time. Truck is well maintained and cleaned and waxed seasonally. The under side of this truck is horrible. There in not a place on it that isn't rust. Shouldn't have this from a us made product. I have older vehicles from the 60's that have sat for year and look almost new underneath. Many other people have had the same problems with these vehicles. I just hope that nobody gets hurt or killed because there vehicles rusts out and causes critical safety systems to fail. I also hope that the NHTSA will take the steps necessary to make people aware and help to resolve this issue. Shameful GM owner.

Brake pedal went to the floor without stopping the vehicle. Found the lines on the driver side below the door on top of the rail were corroded and had burst.

The entire brake line system is rusted, as well the drive shafts and U-joints. This truck is well maintained and these rusted parts may cause severe personal damage.

Failure of braking system due to rusted brake lines, all lines need replacement. Upon attempting to stop the vehicle the brake pedal went to the floor, upon exiting the system was leaking brake fluid directly under the driver compartment.
