problem #5

Sierra 2500 8-cyl

  • miles


Brakes failed to engage, I took it to a GM dealer and upon investigation found a corroded brake line that had failed. As they investigated further they found that all the brake lines were corroded and had to be replaced.I have been a mechanic most of my adult life and have never ever heard of corroded brake lines on a 9 year old truck. This is insane I would like to know why there hasn't been a recall on this very important safety issue"???? what happens when someone is killed?????? I have no problem taking this to the supreme court. When does money take the place of the most basic safety feature known to the american auto makers???? I want everyone to know that this is known problem with many GM auto's and trucks that everyone is aware of and nothing is being done to correct it!!!!!! how do they sleep at night"
