I only have about 3 hours on mine. I noticed a few days ago that when the key was on, the brake light was on. Called a local dealer and he said to drop it by and they would take a look at it. Took it by today and they looked at it while in the truck. The first thing the mechanic said when he looked at the rear adjustment was "it looks like something has hit it". He said part may have to be ordered but didn't think the warranty would cover it. I asked him to just see if it was out of adjustmant. He turned the knob a few turns and all was well. Works like it is supposed to now. I hope this is not a sign of what is to come if I have more problems, large or small.
