I’ve been out in the car a couple of times this morning. On the last trip out, the engine management light light has not. One on nor has the stability control “off” light ???
Go into the engineering mode and see what state the battery is in , but check the engine codes , or you will throw money at things and not necessary solve it
i think most vxr8 have them , the toggle switch on the left side of your steering wheel , push it down then turn the ignition on , it goes into a engineering mode , tells you voltage battery charge/life plus other things
