My battery seems to be losing charge. Then it will completely die. When I charge it on a battery charger for a while it would hold the charge for a a couple of days then die again. I had the battery, alternator, and starter checked and machanic stated that they are all working good. This happens randomly. The driverside power control buttons work on and off. Some days they work and others they dont, almost like a short. This also happens randomly.
