HofstraJet Posted January 2 Share Posted January 2 My 21 Navigator recently started entering deep sleep mode after anywhere from a few hours to a few days. Nothing in the vehicle is on. It is inconsistent as sometimes it will work fine for a week and then a day or two later, deep sleep, and then work fine again for another week or two. I don't always get the deep sleep message on the app, but I know when it occurs as I am unable to start the car from the app (says to start the car and reconnect to "FordPass" - yes, the Lincoln app says "FordPass"). At the dealer now and they can't find anything wrong. Had this issue a few months ago and they found the battery had a bad cell and replaced it, but now it's happening again and everything checks out fine. Any thoughts on what I should check? My dashcam and radar detector are connected to a fuse that turns off with the engine, so they aren't pulling power (and even if they were, why did this just start now when I have the same setup I had since I got the vehicle in 21?). Thanks! Quote Link to comment Share on other sites More sharing options...

Thanks! From afar - I’d say you have another defective battery (or one that doesn’t receive a full charge and the car’s system can detect a partial charge).
