All Service msg came on

Have a 2016 Jeep Cherokee latitude just bought it November for 31,000 miles on it right now I have 35,000 miles on it. I went to town yesterday and my transmission light came on and the service anti-lock brakes light came on and sevice park brake came on it seemed to be running fine but I turned around and went back home. We unplugged the battery check the battery the battery battery is running at 14 volts I don't know if it's ever been changed or how old it is bought it used. I have a anti-theft device in my ODB we took it out put it back in a few minutes later all the lights were gone drove it to town and back no problems.Didn't show any Messages. Got up this morning to go to town and all the lights came back on again did the same things we did yesterday but now all the lights still stay on I have tried to search YouTube and can't find anything as to why all of them came on and cycled thru the same errors but now stays on Service transmission . Won't let me check msgd on steering wheel. And Odometer and tachometers not working. Any ideas?
