While having my vehicle check over for the winter, the mechanic inform me that the front brake lines are very rusty as well as the fuel lines and the cooling lines going to the transmission. This situation is very disturbing since i have very low mileage. The tubing used for the brake as well as the fuel lines should be able to withstand rusting for the life of the vehicle. If the material used by gm was not up to…

The braking system failed when the pedal went to the floor. Investigation revealed that the steel brake line had rusted and ruptured. The only precursor to this was noise from the abs unit at low speed. It appears that all of the brake lines are badly corroded and will need to be replaced. *tr

Main brake line blew while my wife was backing up in a parking lot, the only way to stop was to put the car in park while moving. We had it towed to our local mechanic who had to replace every brake line. The truck only has 68k miles on it. The mechanic said they were very bad and we were lucky to be safe. I cannot believe this issue has not been addressed and recalled by gmc. Our bill was an unexpected $1,300. I'm…

A brake line burst underneath the truck when i applied the brakes with substantial pressure (not enough to engage abs on the dry pavement). Was able to swerve to avoid vehicle that cut us off and use emergency brake to slow/stop vehicle in a safe place. All brake lines were severely rusted/corroded and needed to be replaced. Fuel lines were replaced as well at the same time, due to severe corrosion.

I entered my vehicle to drive home and realized that i had no brakes. After looking underneath i realized that my brake lines were rotted and leaking. One line is currently leaking but they are all in very bad condition. I was left with no option but to have the vehicle towed home. I am going to have to replace all the brake lines as even the ones that aren't currently leaking are in very poor condition. It would be…

Luckily there was no accident as i have been teaching my 16 year old daughter to drive. The brakes felt spongy and not as responsive as normal on my way home from work. When i stopped in my driveway, i looked under the vehicle and brake fluid was pouring out of an apparently ruptured line to the back brakes. There was no warning light on. Regardless of the miles, this truck is barely 8 years old. A quick internet…
