All dash functions stop, and warnings pop up

[Rs31markie]

Hi all, Just wondered if anyone had any idea what’s up with my car. The other day p/steering failure came up and all the dash lights came on, I stopped turned it off and all good after restart, today same thing except this time it wouldn’t start, engine wouldn’t crank over. I’ve searched the forum and most faults like this point to a battery fault??!!! Thanks for any help
