brochue Posted October 25, 2021 Report Share Posted October 25, 2021 Ever since this update my car is dead when I go to start it. I open the door and I get the "shutting down to save power" message. This is after I've been gone for hours. I've made an appointment to take the car to a dealer, the first available was in November. I've tried shutting down everything before I turn car off but this does not help. Everytime I see that message I know I'm going to have to jump start the car. Seems there might of been a bug in the update. Had the battery checked it is fine. Am I the only one having this problem?? Quote Link to comment Share on other sites More sharing options...
homestead Posted October 25, 2021 Report Share Posted October 25, 2021 What version of sync did you update to? You might try pulling sync/radio fuses. My car shuts sync down to save power less than 5 minutes after turning car off. Quote Link to comment Share on other sites More sharing options...
cr08 Posted October 25, 2021 Report Share Posted October 25, 2021 This message will only appear if the vehicle feels the battery is at low enough health to warrant shutting off the radio that early after key-off. Nothing directly to do with Sync. Has the 12v battery been replaced since you've owned the vehicle? If so, do you know if the battery life counter has been reset? This is a vital step when replacing the 12v battery so the vehicle can manage it accordingly. Otherwise it's going to assume a brand new battery is still x years old and may not charge correctly and can result in premature wear. If the battery has not been replaced, it may be due. Most cheap battery testers aren't that thorough and can say it is ok when in fact it may be on its way out. Zathrus and Bill-N 2 Quote Link to comment Share on other sites More sharing options...
