Sometimes after a couple of attempts, or holding the key to Start for many seconds (2-10), it would crank and light off with no problem. No real error codes. Took to the dealer, and they couldn't track it down, as it became intermittent (sometimes it would crank no problem the first time, and other times it would take 20 attempts... you can guess how it acted at the dealer... never a problem). It ended up 'fixing' itself after about two months. I replaced the battery, starter relay, and ignition switch, all with no improvement.
My guess at this point is that the dealer installed 'alarm' (I didn't pay for it, but the dealership installs them on all the vehicles as soon as they roll off the rigs), somehow got it's kill-switch relay funked up by the water. I want to go in and short out the kill-switch relay, as I don't know when it will give me all heck again.
Good luck, and let us know what you find.

I had the exact same problem with my '14 TE on the Mojave Road trail in CA. The deep Mojave River crossing at the end was up to the upper wheel well with my 2.5" lift and 255/75 tires, so I think it was about 36" deep. The truck made it through just fine and ran ok for 2 days afterward, but then continued to get worse every day. Finally, exactly one week later, the truck would not turn over. I could hear the starter "click" each time but it wouldn't turn over. After sitting for about 30 sec, I tried again and it lit up. I proceeded directly to the auto repair shop and dropped it off. They checked it out and replaced the starter and it now runs like a champ.
