yellow battery light
The other day when I stopped driving, I turned off my engine and left the keys in with the music on for about 1-2 minutes. After 2 minutes, the service light with the yellow battery showed up. I took the keys out, and attempted to start the car and it did not lag or sound any different than usual. This happens pretty much every time I do anything in the car with the keys still in. This week I took the car to a nearby shop to get the battery tested, and it showed it was charging, and recharging fine. What could be the issue here?
