Deep sleep recall on the Hybrid Maverick??

[HeyBales]

$94 @Walmart. Battery above it was leaking on it so I didn't buy..

Nice.
I haven't check recent tests - but the EverStart FLA series always seemed to get good reviews.
Need to see if their AGM series is just as good.

I like the ability to return it to any store that has a replacement, just in case you got a bad battery for whatever reason. Had that happen.
And dealing with a weak one for my mom in year 4 once, it wasn't dead yet, but the service desk guy went ahead and did a warranty replace on it. Pretty sure it was pro-rated at that point a tad, but still - didn't require it to be dead or almost like the dealers seem to be.

Now I just need to search around again, last summer none within a decent distance had them in stock.

So, has anyone had their hybrid not start due to the deep sleep issue?

From what I've seen on this forum, if I understand it correctly, the starter in the hybrid runs off of the hybrid battery (directly? / indirectly through the 12v battery?).

If that's the case, then would letting a hybrid Maverick sit for up to a month without driving it be a problem, at least as far as starting it up goes?

I have. At least 4 times. I got an AGM Battery a week ago, and so far so good.

I have a lower end Everstart FLA in my airport car, it's five years old and doesn't have an issue (knock on wood) but I use a 12v solar panel charger to keep it topped off.

FWIW I believe an AGM is the best solution for our vehicles, they (should) last 8-10 years.

Yes, I have. Only deference is I make Ford replace the battery under warranty and not replace on my dime / dollars.

I'm on my third battery replaced under warranty. Dealer isn't interested in diagnosing the problem.

I bought two identical Mavericks delivered within months of each other. One has been flawless the other constantly in deep sleep and non starting (requires jump start).

If this was a software issue why does only one truck have this issue and the other is fine? I am the perfect scientific A/B test case.

Most likely they are not driven the same. One drives 20 miles to say work. Other sits and drives 2 miles to grocery store. Just guessing. So unless they are put to the exact same drives its not a fair comparison at all. Again just a guess.

Both have close to 23k miles in two years. Both driven daily as commuters (minimum 35 minutes one way) and long trips. The one without issues does more short (multiple) trips.

Your experience dovetails with what another member found (forget the individual, sorry, been so many posts on this issue). He tracked the charging profile on the hybrid, and found that the initial charging upon start up is greater, then tapers off considerably.

Cheers.

I was watching Tim Bartz and he mentioned the deep sleep issues and said the solution is to just take longer trips so the gas engine runs more. I thought this was mainly software related and Ford was coming out with a fix by the end of March?

The reason for getting a hybrid was to take short trips! I can't remember the last time my truck wasn't on deep sleep cycle. Most of my trips are under 30 miles. The good news is it always starts, and then all the interior lights go on.

I discovered in the Service Manual last night 2 procedures to be done by the dealers that enables the IPC and BCM modules. Factory and Transport module mode deactivation.
The BCM for the hybrids deals with some of the BMS functions.
Set's the date for battery activated, OLM, starts the count for the charge & discharge tracking, ect.

Before the procedure was done - they are supposed to fully charge the battery.

Made me wonder how many dealers actually fully charge the battery before doing that.
Because here's an extra step the prep crew is supposed to do, who is probably timed on how many vehicles they get ready, and charging up a vehicle - eh...

This could easily set the stage for the questionable charging strategy to make some of the poor quality batteries die even sooner.
Just like doing a Battery Sensor reset is ONLY supposed to be done with a new fully charged battery, because it sets the base level for the next BMS relearn and how it charges thereafter.
But perhaps some dealers did it correctly, and so a driver starts out right.


To the comment about the charging strategy - it's this graph, except in minutes basically instead of hours (actually not usually that many minutes).
So short drive, long drive, city drive, highway drive - doesn't matter on hybrid.

What is the prescribed procedure for a Ford dealership to do a thorough battery test?

I am pretty sure I have seen mentioned on MTC something that looks like it officially came from Ford. Part of a service bulletin maybe? I've searched, but cannot find it.

I would like something that I can show to the Ford service department that will hopefully get them to do a proper test to determine the status of my 12v battery. My truck goes into deep sleep after every time I drive it, even long 4+ hour trips.

Yeah, that's ripe for omission when a delivery of Mavericks arrive.

What are the odds that these amateur dealership hacks will fully charge the battery and do the BMS reset, given that half of them can't even drop the tire shipping pressure to the correct driving level or top up the fluids to the required levels before you get the vehicle.

And here's the process they aren't probably thrilled about doing anyway.
Well - perhaps if they could do the 125 miles in some vehicles!

Factory Mode Deactivation
NOTE: During vehicle build, some modules, such as the IPC and BCM module are set in factory mode. Factory mode reduces the drain on the battery during longer periods where the vehicle is not used. While in the factory mode, various systems may be altered or disabled and the IPC displays FACTORY MODE CONTACT DEALER in the message center. If the vehicle is in factory mode, the system automatically reverts to Transport mode after 60 ignition cycles. If the IPC displays TRANSPORT MODE CONTACT DEALER, refer to the Transport Mode Deactivation procedure in this section.
1. Place the ignition in the OFF position.
2. Verify the battery is fully charged.
Refer to: Battery Charging (414-01 Battery, Mounting and Cables, General Procedures).
3. Without push button start, cycle the ignition from off to on 60 times.
4. NOTE: One IKT must be in the vehicle.
With push button start, press the Engine Start/Stop button 120 times.
5. Refer to the Transport Mode Deactivation procedure in this section.
Refer to: Transport Mode Deactivation (419-10 Multifunction Electronic Modules, General Procedures).

Transport Mode Deactivation
NOTE: After vehicle build, some vehicle modules are set in Transport mode including the IPC and the BCM. Transport mode reduces battery drain during longer periods where the vehicle is not used. While in transport mode, the IPC displays TRANSPORT MODE CONTACT DEALER in the message center. Various systems may be altered or are disabled when in the transport mode. The vehicle automatically reverts to normal operation mode after being driven 201 km (125 mi). The vehicle can be manually taken out of Transport mode using this procedure.
If the IPC displays FACTORY MODE CONTACT DEALER in the message center the vehicle is set in factory mode. The system does not automatically revert to another mode and must be manually set to either the transport or normal operation mode. Refer to the Factory Mode Deactivation procedure in this section.
1. Place the ignition in the OFF position.
2. Verify the battery is fully charged.
Refer to: Battery Charging (414-01 Battery, Mounting and Cables, General Procedures).
3. Place the ignition in the ON position.
4. NOTE: Steps 4 and 5 must be carried out within 10 seconds.
Press and release the brake pedal 5 times.
5. NOTE: The IPC message center indicates NORMAL MODE when the procedure has been successfully completed.
Press and release the hazard switch 2 times.
6. Start the engine.
7. Place the ignition in the OFF position.
8. Verify the RKE works correctly

Deep sleep isn't enough, if truck starts. For most service departments anyway.
Perhaps you can get a real friendly one. Because if it starts not a warranty issue yet, for them to get paid dealing with it.

Need to get that jump pack - and that day it fails to start take it in.

Here's the SSM you are thinking about.
Battery drain issue, so dead. Since that can kill a battery if it happens enough - they thoroughly test if it's damaged enough yet to get a replacement.
But perhaps they can charge their time against this even if you don't have a dead battery yet.

Usage at low voltage will take longer to get there compared to parasitic drain overnight.


SSM 53087 2022-2024 Maverick - FHEV - Intermittent 12V Battery Drain When the Ignition Is Turned Off
Some 2022-2024 Maverick vehicles equipped with 2.5L full hybrid electric vehicle (FHEV) powertrain may experience an intermittent 12V battery drain condition when the ignition is turned off.
If the 12V battery drains, perform a 12V power reset to the vehicle by disconnecting the 12V battery negative cable for 5 minutes.
Fully charge the 12V battery and use the Rotunda GRX-3590 or DCA-8000 tester to determine if replacement is needed.
If replacement is needed, fully charge the new battery and perform a battery monitor sensor (BMS) reset.
Engineering is currently working on a software solution for this condition that is expected in the first quarter of 2025. Monitor OASIS for additional information and schedule service appointments for customers once the repair becomes available.
