“I was traveling close to my home and was making a left turn on a country road. I went to apply my brakes with no result. The peddle went all the way to the floor. I shifted the vehicle into low gear and finally made it home. I had to have the vehicle transported to a shop for repairs. The cost to fix the brakes lines, master cylinder - $1000. Not happy with Gmc and will probably never buy another american made vehicle. I also have a chevy tahoe and I have had nothing but problems with that vehicle as well.”
