I haven't seen that issue anywhere either, could be a one off issue. Glad they were able to get it fixed. It might be worth posting the part number in case anyone runs into a similar issue.

As for the drive by wire, I still can't get used to it. I hate how it responds (or doesn't I should say), there's too much delay between letting off the gas and the truck settling down. I sit in traffic alot on the way home from work so I usually drop it into M, then fluctuate between 2nd and 3rd so that the truck isn't shifting between 1-4 a bunch (less braking for me). If I'm sitting in 2nd, give it gas for a bit and immediately let up, it seems like it takes a few seconds for the truck to figure out, "oh hey, he let up on the throttle, we should probably cut the fuel"...
