Brand New Maverick, Deep Sleep before driving off the lot.

At that voltage your +12v battery is only at about ~65% charge after transportation.. Charge it overnight with a quality charger, perform the reset, and enjoy your truck.

Is it recommended that all maverick batteries be charged upon delivery?

So there is not a TSB... yet. There is on every other vehicle that suffers from this issue. I'd be on the lookout for one and it's one reason why I avoided the hybrid (but I still do like the hybrid). The drain on the Escapes is a huge problem and judging by these forums - it's the same for the Maverick too. I'm only relaying the knowledge I have from that setup - because it's the same deal regardless if the battery is different. That's what I meant.

Did you replace the battery with a larger capacity one? What is the difference compared to the stock one?

What is 'this issue", and 'the same deal" (as the Escape)?

Some Hybrid Mavericks suffered Deep Sleep and/or no start from a known main cable issue going to the junction block under the hood and some of the concerns were remedied with a main cable replacement. Did the Escape encounter that problem?

Some Hybrid Mavericks suffered Deep Sleep and/or no start from a known cold solder joint to the lug on that adjacent underhood terminal and some of the concerns were remedied with the lug replacement. Did the Escape encounter that problem?

Some Hybrid Mavericks suffered Deep Sleep and/or no start due to a faulty battery. Replacing the original battery resolved some of those concerns (as it did mine).

I provided the link above to my Hybrid battery replacement thread. At least at the time, all Group T4 batteries irrespective of manufacturer had the same capacity. I'm not aware of any advances.

My ...guess... is that a good overnight charge will remedy the OP's issue... The new Hybrid +12v batteries probably sit for 1-3 months, are installed during the build, then sit another month in shipment and could likely use a good charge before being placed into service..

good luck

Working with Ford via messenger, but for the moment I've not been able to get the battery over 12.5v. I'm going to pick up a slower charger tomorrow and see if that will do it, but if not I'll update.

It's a group 48 replacement and resetting the BMS in forscan. Going from a 45ah to a 70ah.

The issue is constant drain below safe voltage levels. The thread is 10 pages and in it there is the official TSB as well as the voltages the battery should be, but the 45ah would never get to.

Which is why I asked what is the difference in batteries you swapped out? Anything? Have you tested voltage? How are temps where you live? Etc etc. I can't help but wonder if you put a band aid over a wound that needs stitches, and FORD has yet to address the issue on the MAVs the way they have on the Escapes.

First attempt with my current charger didn't do it, going to pick up a charger that will trickle it in today.

I've pointed you to my Maverick Hybrid battery replacement thread 2 times in post #34 here, I can't read it for you...

It's not clear why you continue to co-mingle the Escapes issues with the Hybrid Maverick's specific Deep Sleep and/or no start issues.


Does the Escape have a known cable issue like the Hybrid Maverick does? I suspect not. Ford has addressed the cable issue, there are many, many threads here.

The Hybrid Maverick uses a group T4 battery, without cutting or further modification there is virtually no room for a physically larger battery under the seat of a Hybrid Maverick

Unless things have changed in the last ~week, currently all commercially available Group T4 batteries have the same capacity specs, I used a Diehard to rule Motorcraft batteries out of my failure equation.

My Hybrid Maverick was failing every ~3-4 days for ~6 months. Temp was not an issue in my case. Every time it went into Deep Sleep I put a quality charger on the truck overnight, and drove it almost every day. The battery would fully charge, then drop. I have several high-quality Fluke DVMs as well as a Fluke clamp-on meter to test current draw/drain. I did not see any unusual high parasitic drain on my truck when it off. In my case, mine was a battery failure. I've experienced multiple Motorcraft Infant Mortality battery issues on some of my other new Ford vehicles in the last 15 years (my Raptor, one of my Platinum Expeditions, and my wife's Platinum Explorer, while the batteries in some of my other new Ford vehicles have lasted for 5-7 years w/o issue. .

My truck has not gone into Deep Sleep since I replaced the battery more than 3 month ago now.

Already got it sorted, thank you!

That’s Old Man’s answer to every post!

 

[ArkyMosuke]

Small update, got a better charger and it is indeed showing the battery at 60%. So I gonna leave it on the charger to 100% and see how it goes.

 

[ArkyMosuke]

Charged to 100%, tested and got 13v. Did a battery monitor system reset, started vehicle. Message didn't go away. Unpaired uninstalled, reinstalled, and repaired my Ford pass app, message came back immediately.

Problem persists.

Edit: On the bright side, I did get my 42k Ford pass reward points.

You can take the battery to AutoZone or advance where they can charge it full overnight

 

[samspritzer]

Get it addressed. It's a massive issue in the Escapes and here too, but I feel people are less informed about it here.

They used a crappy battery and they have an updated one you need to swap it with. Do not accept the dealer telling you anything else.

My dealer keeps saying mine is fine. I imagine that if you're not getting a bad battery reading, how else can you convince them to replace it unless this is a directive from Ford.

I never could convince any dealers I have the TSB 22-2340 issue. Ford finally issued the 22B39 Customer Satisfaction Program, but that was issued right after I got my Maverick back from the airbag recall debacle, which cost me six weeks without the vehicle.

I got 22B39 too and took mine in. Guess what!? They thought they had the overlay in stock. It turns out it was for the non-hybrid and that the directive didn't even mention there is a difference. The service advisor and I agree that we'll wait for the replacement to be done and hope that solves the DS problem.

 

[ArkyMosuke]

Stopped into the dealer today, have an appointment for the 13th, gonna do a software update, there's some TSB, and then try and track down the deep sleep issue of it persists. The lady in the service department literally said "not this again" when scheduling it.

I don't know if that's a good or bad thing, I guess it at least means they are familiar with the issue in one way or another. So far they have been a pleasure to work with, so here's hoping it continues that way.

Side note, when it rains it pours, I got a chip in my paint from a rock on the rock kicking up from a guy going in the opposite direction. Size of my pinky nail and right on the edge fold of the front left fender. Gonna have to get that fixed too.
