I know we have a big thread on the light & serice soon message. I get the light but message in the center screen (don't have nav). SGII of course doesn't read that message.The first time I saw the wrench was during our hot spell (105+) for over a week. it came on 3-4 times, but of course cleared on restart. That was July, no wench since. It came on today (76°) in the middle of my 5 mile commute. Stop at PO and of course it cleared. So before I drag myself to take it to a dealer to hear "could not duplicate", can anyone else with an 08 conirm if the batt actuator problem is just a wrench, or if a service message also appears?
