1. My headlights dim on and off. They stay on but dim and go back normal. on 2005 Hyundai Sonata

2. My Esc light keeps coming on? It will go off when I turn on and off the car?
3. My tire keeps losing air pressure. I have to put air in it once a week, and 4 or 5 places says there is nothing wrong with the tire?

have codes scanned and poss valve stem is bad in tire.
Thank you very much "Greg's Orange Auto". That is much appreciated.
Headlights that dim, and brighten sometimes indicates an alternator or charging system problem. The tire might have a leak at the bead and rim, small puncture, or valve stem leak.
