Because your battery isn't dead. H
You need a new one.
Perhaps it needs service.
Could be a reason as simple as a headlamp burned out to a sensor malfunction. Get the codes set in the BCM and look it up.
Probably loose gas cap syndrome. Be sure to tighten cap past a couple of clicks after getting gas. Rick
Your service light is broke and is in need of service.
Any one of a dozen possible reasons. Gas cap not on tight or defective, fuel trouble, ignition trouble, faulty sensor somewhere. You'll probably have to take it to a shop and get the fault code(s) from the computer read. If the light is on a code has been generated and stored.
