Before This Oil Change The Clock will turn off when I turn car off. Got my Oil Changed at Blue Sky Auto & Tires this morning. They Ran a Test also on What problems my Car has.Now When I Turn Off My car The clock stays On

I doubt the garage did anything while servicing the car that would effect the clock.

Do you have anything plugged into the power sockets in the car? A phone charger or something like that?
Is the car still fitted with the original Hyundai radio or has an aftermarket unit been fitted?

If I helped you fix it, why not...

Your support is greatly appreciated​
