Deep Sleep Mode

[Action]

All of the newer vehicles built in the last say decade or two have parasitic drains due to electronics.

Meaning something (electronics) is still drawing some current after the shut down sequence has completed. However, that draw should be very very small. Something in the range of 50 to 80 mili-amps should be acceptable. (Thousandths of an amp) Draws in that range or less should leave enough of a battery to start the engine a week later with warm ambient temps.

Not something measured unless a no crank situation occurs. Then charging and testing would be the next steps.

I have had that problem twice of the past year. The battery was replaced each time. I believe something is using power while the vehicle is off as I sometimes get in and the screen tells me to turn the vehicle on or it is going to cut power.

Was this before you even started the car? I’ve had that problem. I sent my car in for service. They said the battery is fine. They also said I should start the car at least once a week to charge the battery because it appears I don’t drive it often. in reality, I drive it every day. I feel like I’ve just been brushed off.

My Lincoln dealership updated the BCM for SSM 52445, recharged my battery to 80% ( the SOC was low at 35% when they checked it) and reset the BMS on my 2023 Lincoln Navigator with just 2,500 miles on it. I just got the car back today so it will take a few days for me to see if the repetitive deep sleep message issue is resolved.
I also had a click then double click sound every 25 seconds that was coming from underneath the hood after the car was turned off. I also had them had replace the trunk liftgate struts as the liftgate was squeaking loudly when opening or closing the trunk. Hoping that either the SCM update or the replacement of the liftgate struts resolved the battery drainage and clicking noise. No clicking noise so far!

The clicking is something I notice when I'm near the car with my key or phone linked to the car with lincoln way app. Was the clicking resolved? What did they do for that?
