Bought a 1999 GMC Sierra 3500 4door 8ft. Bed with 30000 miles on it in 2001. First brake line rusted out in 2005. Second line from front to back rusted and broke 2008. Fuel line rusted and leaked gas all over my driveway 2010. Today that same truck? is in a repair shop because the frame by the steeringbox and passenger side front rusted and cracked. Its a shame GMC used such bad materials for their trucks. My truck now has only 97000 miles on it. If it cant be fixed safely the scrap yard is its next stop and a Ford will take its place. To bad GMC you lost another customer.

I was driving in town closing in on an intersection as the light began to change red, two sedans were in front of me so I applied my brakes allowing plenty of time to stop when without warning the brake pedal sunk quickly to the floor and did not slow at all. I had to veer into the turn lane but could not make the turn due to speed and oncoming traffic. I cleared the intersection and had to veer into a busy parking lot ran over a stop block and continued through 2 yards and out a driveway back onto yet another road where the vehicle finally came to a stop. Both yards had people in them and it was a miracle no one was hurt. This was the most terrifying driving experience in my life. Upon inspection of the brake lines I found a tiny hole in the line crossing the engine yoke. As I furthered my inspection it came to my attention all the brake lines resembled burnt corn flakes and must all be replaced.
