Truck has just over 150k miles. Maintained well and garaged when possible. 1) noticed a fuel smell from the driver side door area and after parking for a long weekend, a small pool of liquid formed in front of the driver side rear wheel. It was fuel dripping from the line leaving the evap canister that had rusted through. Resulted in a $600 repair to replace all rusted fuel lines so as to eliminate the risk of fire. 2) when approaching an intersection to make a left turn and slowing down the brake pedal pushes to the floor with no stopping power at all. Used the engine/trans in manual mode to slow the truck down and avoid an accident. Driver side brake lines are blown out in multiple spots near the abs module due to corrosion. Potential cost based on research is in the $1000 ballpark. This level of rust on critical vehicle components is irresponsible and potentially deadly. Gm needs to take this more seriously and realize that their cost-cutting measures are putting people and their families in grave danger.
Rusted out fuel lines. Had to replace all fuel lines. Rusted out brake lines. Brakes gave out while driving. Luckly no accident. Had to replace all brake lines.
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.
