This happened to me on the third day of ownership (<200 miles). I got the "Stop/Start Unavailable Service Start Stop" but when I tried to move the car it would move maybe a foot and then seize up. It also said something at one point about me needing to put it in Park but that didn't help either...
Just got a new gladiator overland and it's not working on day 3.
It had 100 miles on it out of the dealership. I drove it home (100 miles) and all was great. Next day drove it and it was great.
Then the third day I got a message when I turned it on "Stop/Start Unavailable Service Start Stop."...
