Sierra 3500 4WD 8-cyl

  • 79,000 miles
I went out to my truck in the morning and my dash board indicator told me to get my brakes checked; everything was fine the night before. I brought the truck into mymechanic and found out that my brake line is corroded and broken. Also found out that this a recurring and consistent problem with the GMC Sierra. I have my truck serviced by an authorized service center on a regular basis and this has never been mentioned to me. This needs to be a recall item! serious safety threat. Cannot imagine what could have happened if this occurred 2 days later when I was pulling our 40 foot rv. Shouldn't GM be responsible for this? my truck is now in the shop getting the brake line replaced.
