I have the 3.0. It has happened to me 7 times within the first 5k miles. Been to the dealer 3x. Last time they claimed to have re-torqued the fuse box bolts. Other than that they say they can't replicate and usually mention that they "checked all the software". First new truck i've bought in a long time so its very disappointing performance from a $60k truck.
To recap what my truck is doing
First two times, i was using key fob, and the start would spin but not fire.
3rd time - starter spun but would not fire, then it would not crank after at all for multiple attempts. I had it towed to dealer but it actually did crank as he was putting it on the tow truck.
Times 4 - 7, push the crank button on dash, starter runs for ~10 seconds but no fire, and I can't get it to stop. Then it has crunk on 2nd attempt every time.
