Thank you! While I realized running the cam constantly is not good for the battery, I had no idea there's a separate power adapter to eliminate that problem. Mine's not a Garmin, but certainly appreciate the info. I'll try turning off the parking mode and see if that helps.
You are correct. Apparently, I turned off the deep sleep notifications from Ford Pass, but when checking the app directly, that's the message I was getting, so yes, the issue is due to deep sleep. Thank you for responding.
Sound advice. When the lights fail to light, Ford Pass reports deep sleep when launched. I turned off notifications from this app a couple months ago which is why I didn't consider deep sleep from the get-go. Thanks to the members, I now have a pretty good idea what's causing the light fail and some ideas on how to solve it.
In the case you mentioned, right after driving the battery has enough charge to light up the interior. After it's been sitting a while, the battery does not have that same level of charge so the computer doesn't allow the interior lights to come on. Probably a priority thing, Ford would rather you not have interior lights and the truck start than have interior lights and the truck not start. But it sounds like the battery is either defective, or is too small to keep the necessary level of "juice" needed for everything to work after the truck has been at rest for a period of time, which is hella annoying and should be addressed under warranty. I wonder if sitting in the hot temps of Mexico has anything to do with this?
Thank you for sharing. I will definitely add this to a possible solution. Any improvement with the battery drain using the new battery?
You bring up some very valid and interesting arguments. Your 'priority' comment sounds reasonable. Better to have enough juice to start up the truck . . . not needed when exiting.
You are correct. I've used this procedure many times not only with the Maverick but with our Palisade that also has the push start feature. Thank you for posting. No doubt others will read your post and gain from it.
I hear you. We should not need to recharge our battery every day, right?!
Great tip! That worked to reset the BMS and now when I open the door or unlock, the overhead courtesy light works. You did say it might be a temporary fix, but I'm wondering since I turned off parking mode on the dash cam, resetting the BMS might last longer. I'll also check the mirror situation. Ironically, many of us owners were chastising Ford for not including an auto dimming mirror with the Maverick; perhaps now we know why.
I honestly don't think it draws any power since it uses a switched wire. Most likely it's the dash cam or just the fact that the battery is utter garbage. Most new vehicles also have circuitry which allows the alternator to essentially turn off and not charge all the time since the alternator puts more load on the engine than you would probably imagine. This is in pursuit of more efficiency so manufacturers can eek out as much gas mileage as possible due to fleet standards. I don't know if this is the case with Ford but it's common practice among other manufacturers and I wouldn't be surprised if Ford is doing it as well. Add that to a trash made in China battery along with a dash cam and short to medium length trips and it's a recipe for deep sleep mode on the Ford.
Your comments make good sense and your point about the alternator made me ask myself, "does the Maverick even have an alternator, or is the 12v recharged from the lithium?"
That makes sense. Same battery used in both hybrid & Eco, so both would experience deep sleep issues. I was thinking it was only the hybrids with the issue, so thanks for the clarification.
