Stopped to get gas. As I was pulling out the lot, brakes went to the floor. Tried to pump brakes to pressurize. I decided to pull over. As I was turning off road to investigate I heard a loud pop. Check brake light and audible came on. Pulled over immediately only to discover brake line had ruptured. Further investigation revealed all brake line tubings were severely corroded. Chevy had finally made wise decision to go stainless steel for exhaust system. Puzzling why they did not make same decision for the brake lines. Brake system is critical safety item that should mandate highest safety measures. Not the exhaust system! I was fortunate failure did not occur on the highway. I was able to tow the vehicle to dealer for repair. While pulling into parking stall at the dealer, I heard another loud pop. And even though my foot was on brakes, the truck began to accelerate. I had to put the truck in park to stop. It appear there was just enough stopping power to get off the road. Must advise anyone who experience this not to attempt to drive home! No matter how close. I was considering this option. Good thing my good sense prevailed.

The suburban would stall while waiting in drive thru lines. Several times. Dies while in gear, put in park and would then start up. Dealer could not find any problems. I knew I had gotten a bad tank of gas, 2 months earlier. So we tried fuel injections, etc... The suburban would die and would be towed back to the dealer. They decided I needed to replace the fuel module. $800 later and it was still happening. The dealer was driving my car more than I. Putting miles on the car and gmc decided I had too many miles on the vehicle to do anything about it. Now, it dies while driving the vehicle. One year later and the problem still exists and no one has figured it out. I am scared to drive the vehicle and mostly dissatisfied that I spent 45k on a vehicle and then when it fails no one knows how to fix it. They just want you to buy a new vehicle.
