Battery Saver Mode - Constantly

[Raggy]

Good afternoon

I recently got a 2024 Maverick Lariat Edition about 8 months ago.

For the past month or so anytime I drive to work in the morning I soon get the message:
Vehicle in Battery Saver mode and I need to drive it to recharge the battery to add remove features...
So I drive it... park it at home, no issues, next day I drive to work... same thing. Battery saver mode again.. everyday.. without fail.

This is getting really annoying what is causing this to go into Battery Saver Mode? I am not leaving on the lights I double checked everything.. What is going on here?

I just want things to work.. correctly.. Especially now that the weather is starting to get cold.. I would like to be able to remote start my car to warm it up... and not deal with this BS BS... (Bull Sh!t Battery Saver). 8 months old battery shouldn't be having issues....

I've just accepted it at this point. It will always start and I'm able drive but the interior dome lights won't come on automatically nor will the 3rd brake light when I unlock the car/get and before I start it up

Do a forum search, what you are experiencing is the norm, welcome to Maverick Hybrid life. Unless you drive 2 hours a day or more, this is just how it is. It started for me less than two months into ownership. Dealer test the battery "it's fine", yeah because they put it on a trickle charger. I can do that myself and skip the 4 hours at the dealership.

There is no real fix, it's a combination of draw from all the computers, poorly coded charging software, an undersized SLI battery(standard lead Acid battery), rather than a AGM deep cycle and other things.

Some of us just installed an in-car trickle charger to get by, I hang the power cord out under the closed back passenger door, once a month I'll fully charge and it goes about a month before getting Deep Sleep messages again. If you do charge make sure to connect the negative charger cord outside of the Black Block BMS sensor on the negative terminal of the battery, then the Mav will sense all of the charging and won't have to reset BMS after. Go back to the dealer and they might give you a new battery, and hopefully it helps Ford realize it affects every single Maverick.

One of the advantages of a discussion forum based on a common subject is that you can search the wealth of past discussions for your answer prior to asking via another post. People who have given lengthy answers before may not be around or even willing to answer similarly again.

I retired shortly after purchasing my Maverick new on 5/22. Both it and my bought new 19 F-150 get driven very little and quite often show me the Deep Sleep message before starting them.
Never a problem with either truck.

one of the advantages of a discussion forum based on a common subject is….. that I can post a new thread and get a singular answer or a new perspective instead of reading posts on older models of trucks that may have nothing to do with the problem at hand.

yes I searched, yes I read.. do you think this is my first time on a forum?

No actual solutions were offered aside from deal with it, Aka not a solution so why would I not ask again?

deal with it. Is not an acceptable solution for a brand new vehicle, in any respect

Does the deep sleep inhibit your ability to use the vehicle or are you just annoyed by the messages?

Surely the person who has the answer to this problem looked past all of the other people who had posted of the problem and was waiting for you specifically to ask.

My apologies.

You don't have to search. The solutions have already been mentioned in this thread. Buy an AGM battery and use a battery maintainer. No more frustration.

Ford won't do anything about it, other than swapping in a new battery, which isn't a fix, so you don't have much choice.

What performance issues does this cause?
Remote start?
No start……

3 yrs of truck.
No changes between those years.
May not be aware of that.

I'm sure you've done this on many forums, indeed.
Actually solutions were given.

Now look at the 5 Similar threads listed below and you'll see several solutions given.
And the reasons why.

Sorry, but "deal with it" IS the answer at least from a Ford perspective. As you should have read many times on the many, many posts on the subject, there are basically 3 primary things you can do:

1) Turn EVERYTHING off (remote start, app, etc.) which will get you about twice as long (battery will lose about .05-.1V per day instead of .2V per day). Locking the door also slows down but does not eliminate the truck "waking up" constantly. On at least a dozen posts last year you will see that myself and a few others did EXTENSIVE research across multiple months (I literally checked and recorded the battery voltage every day for almost 2 months). Nothing has changed in the last 24 months.
2) Buy an AGM battery (again, doesn't fix the issue but gives you a few more days between drives before going into battery saver at roughly 11.8V), The Ford Battery Monitor is actually DESIGNED to quickly kill the provided lead acid battery since it limits the actual "full" charge to around 80% capacity [the assumption is that this is a legal move to keep the battery from potentially over-heating/over-charging since it is physically located in a passenger area]. A lead acid battery needs to be over 80% charged to not start sulfating (a quick Google search will provide you with all the science behind this).
3) Put a battery-minder or trickle charger on the truck about every 3 days. This is what I personally have resorted to doing since I sometimes go a week between drives.

Well, I guess is a 4th thing which is whine and moan but that isn't going to get you very far with Ford or on this forum. Folks on this forum have probably invested 1000+ hours on this issue and it still all boils down to the 3 main suggestions above.

Well, I guess there is also a 5th option which is sell the truck and buy something that doesn't have this issue. However, zero clue what that vehicle may be since there are complaints on pretty much every major auto forum (Toyota, KIA, Chevy, etc.) I have read in the last 3 years (since pretty much all new vehicles have power sucking computers and other features in them). Some are better than others but it is a common issue.

I just had this issue fixed on my 23 Hybrid this week. The BMS recall does not correct the issue, and the bad software means that the damage is already done. If you check your battery voltage, it only holds overnight at 12.1V or less, or about 50% charge. It should be at 12.6V to be fully charged. When the battery drops below 12.0V or about 25% charge, then the system goes into battery saver mode and shuts down normal external operations, interior lights when the doors are opened, etc. The problem starts with the BMS not allowing a flooded battery type to get to at least the 95% charge required to prevent sulfation. Your battery is now sulfated and will not hold a charge anymore. Its covered under the 3/36 vehicle warranty. If you're still in the warranty period, then take it in to the dealer for a free battery replacement. IMHO because the BMS is preventing the battery from charging correctly, its going to happen again, also probably within the warranty period.
A much more expensive AGM battery will last longer even with the improper charging level, but will eventually have the same issue. Another temporary (and intrusive) fix is to put a trickle charger on the battery every day. The correct fix is for Ford to reprogram the BMS to allow the correct 100% charging level to occur. Someone in xcharge of the Ford BMS software group needs to go back to school and learn how batteries work before they are allowed to work on the software for them.
