Will not start after multiple stops

The battery cables were loose and there was corrosion. I had that fixed today. The "parking assist disabled" message is still showing (that was not there before this happened also), but the car did not lose power today after multiple stops. I will check this wire to the fuse box that you have suggested also. I had an engine light and gass cap light on that has disappeared now since the car did not start, but I expect those to come back within twenty four hours. Any other ideas please forward. The work done prior to the power failure to start was a radiator replacement and oil and filter change. The car was at the shop for a month.
