Sometimes when i come to a stop at a light/sign and auto stop kicks on normally it leaves ac,radio etc on but occasionally it will kill all power for a split second as soon as I let off the break. Its not to big of a deal to me but when im listening to music through Bluetooth it gets annoying. It doesn't do this to often maybe 3-4 times a week sometimes it won't do it for a few weeks. Could this be the auxiliary battery not having enough voltage to keep them on or something else? Thanks.
