Had mine quit on me at 1000 miles. Threw a bunch of warning lights, had to flatbed it to dealer. Turned out to be loose connection at the pcm. A week later the check brake system light kept showing up! Had vaccum hose and sensor repalced, so far so good!! So frustrating!!!!
I also don't have them and kinda wish I did! I didn't realize they could be there until i was given a loaner which did have them. Been curious about this ever since. I'm glad someone started a discussion about this!
Just got mine back from the dealer for the same issue, they replaced a vaccum hose and sensor. So far so good! previous to that it was in for a loose connection at the pcm. Whole truck shut down on me, had to flatbed it to the dealer. All this in the first six weeks of ownership!
