So my two-week old ST wouldn't start this morning, after driving fine yesterday. Oct 30 build date. Deep sleep message hit my Ford Pass in the middle of the night, but clearly the voltage was truly low. It measured 3.5 V on the roadside assistance guy's portable booster.

It barely started off the booster (and wouldn't even click on a smaller one that hotel security had, and promised they kept charged).

I'm at the Quick Lane in Orlando... wife is thrilled I bought this damn thing and its effect on our vacation.

I saw a couple mentions of reprogramming that appears to have fixed the drain issue, right? Of course the main service says they can't look at it until Monday... Not helpful when we're driving back home tomorrow. Is there a TSB or anything I can mention to my home dealer?

Chances are you have a bad battery.. hundreds of thousands of them produced a year.. someone will get one.

The software update doesnt prevent battery drain, it prevents the deep sleep from occurring if I recall correctly.

I'd call a dealer and see about swinging by and getting it swapped out. 3.5 v.. that battery is junk now if it wasnt before.

Software update corrected the battery drain on mine..... it triggered the deep sleep because of the battery drain , after the update I haven't had the issue again. They never replaced my battery but since it's a lease I didnt care .

Original poster here with an update! I recently took my Explorer in for service (recall), and they also updated the software due to a bulletin associated with cars built pre-August. I believe it is the same one referenced here:

Possible Deep Sleep Fix

I'm happy to report that unlike the last time I left it at the airport, the car was fine after spending nearly a week at the airport over Thanksgiving. I'm cautiously optimistic that this issue is solved.

Thank you for that. Mine is after that build date, so I'm hoping I just hit the bad battery lottery like @blwnsmoke said, and the new one stays charged. I'll post back here if it dies again. I know it's not the best test, but any validity in taking a voltage measurement in the morning, without disconnecting? What should I expect if there's no abnormal load over night?

I bought my explorer the first week of Sept 2019. On Oct 9th I went out to start it and it was dead, the dealership replaced the battery. On Nov 9th (yes exactly 1 month), it was dead again, they jumped it and all was ok. On Dec 9th (yes again 1 month), it was dead again. This time no jump worked and has to be towed. I told the dealership I'm not picking it up until they find out what the heck is draining my battery. The solution is not that I have to drive it or run it every 2-3 days. No one should have to do that. I have not had this issue with any other car. I work from home so I do not drive my vehicle every week.

This problem has been solved, it needs a software update from the dealership. Mine did the exact same thing when I got it.

Yes they were actually able to do that update. Hopefully it is fixed.

I have had my 2020 Explorer Platinum about three weeks. I recently left it in the garage for a trip (6 days), and on the return flight home I received a "Deep Sleep Mode Activated" FordPass alert on my phone. When I got back to the car, it would not start or respond, and acted like it had a completely drained battery. I was forced to jump it to get it going (last night).

I've triple checked for lights or other accessories on, and found nothing. The auto-start stop also seems disabled, which makes we wonder if there is a battery issue. Unfortunately, I just received another such alert, and am now wondering what to do next on this Labor day weekend. Anyone else experienced a similar issue?

P.S. I dare you all to figure out how to remove the battery on this vehicle.
Yes I found the battery in the compartment under the passenger side under the wiper, I had that problem also and had to have it jump and drove around and the next day it did the same thing, So I had it towed in to the Dealership and they put it on the machine and charge it up and told me it was fully charge, And I was willing to bet my life that it wouldn't start the next morning, But it did, And Monday Jan 20th again my 2020 FORD EXPLORER ST went in to another Deep Sleep Mode @ 3:19 am and I called Roadside and they had to use 2 jump box to get me started and I took it to the dealer and they said they've never seen this before, I'll have to make an appointment so they can put their Senior Mechanic on it.

That is also because they must have done the software update.

Ford came out with a fix for this. SSM 48268 it includes reprograming of BCM, TCU and APIM

Summary

Some 2013-2020 vehicles equipped with an EVDC air conditioning (A/C) compressor may exhibit poor A/C performance/improper climate function. To support the proper diagnosis of this compressor, the EVDC control valve tester has been provided to each U.S. dealership (339-EVDC100). Ensure the A/C system has a full charge prior to any compressor diagnostics. To support the proper diagnosis of this compressor, the EVDC compressor tool must be used, and the results recorded in the Technician comments field with the warranty claim. This tester will help reduce the potential for misdiagnosis and unnecessary compressor replacement. Refer to the Rotunda catalog for a video and user manual which provide detailed operating instructions.

Here it is:

SSM 48268 - 2020 Explorer/Police Interceptor Utility - Discharged Battery/No Crank - Built On Or Before 30-Aug-2019
Some 2020 Explorer/Police Interceptor Utility vehicles equipped with SYNC builton or before 30-Aug-2019 may exhibit a discharged battery/no crank condition. This may be caused by the software in the accessory protocol interface module (APIM), body control module (BCM) and/or the telematics control unit (TCU) module. To correct the condition, reprogram the APIM, BCM, and the TCU using the latest software level of the appropriate Ford diagnostic scan tool. If the BCM softwareupdate is not available in the FDRS Toolbox, a software fix is being developed.As a temporary fix, uninstall and reinstall FDRS selecting'remove all data'. If the battery drain concern is still present, follow normal diagnostics in Workshop Manual(WSM), Section 414-01 > General Procedures.

I thought I would report an update here as well. Mine has been at the dealership for over a month now, and the last time I was able to see it had been moved was exactly 1 week ago. This is one issue they claimed to have fixed, but just a few minutes ago I received a notice that it went into deep sleep mode. Just wondering if anyone else has left the car alone for more than one week. It's supposed to be 2 weeks before it does that.

My 2020 Explorer had that problem and I took it to the Dealership and they Reset all of the modules, and Thursday 7th of Feb my truck sent a message to my Ford App.

Same issue for me. Received multiple notifications regarding the deep sleep mode. It has never sat for more than 48 hours. Took it in to the dealer, they removed the battery and hook it up to a battery charger until fully charged, completed a load test on the battery and it failed. Battery was replaced and no issues so far.

They did the same and said that the battery was charging and the next week I'm back at the Dealership but I decided to go to another Dealership and they reprogrammed all of the modules, and again on the 7th of this month it died again so I called Roadside and they came out and jump my truck again, now If it happens again then I'm going ask for a new battery.

According to post #68, a software update is required.
