Interior lights not coming on when entering

[ZABSMAV]

I have the same battery issue with '24 hybrid. Battery in deep sleep mode and no interior lights. Dealer replaced the battery a year ago and now having the same issue with replacement battery. If I drive it on about 20 mile trip the battery stays up for about one day then back in saver mode.

Get used to a yearly battery replacement. Until Ford gives us all their promised permanent fix, that is all we will be getting. Just remember to get in writing with each free battery replacement that the replacement battery has a new 3 year replacement warranty.

A trickle charger?
I drive it 25 miles to work and 25 miles back everyday and then four or five times after that in the evening.
Why would I put a trickle charger on it? or hell when? I don't get it.

Check your battery volts in the morning before you leave only takes a short minute from under the hood...it might say a lot...then go from there

I'll take a meter to it today but damn I may need a new batter in a 2024?

My Apr '24 bought 24XLT mfg 3/24 - battery from 48 wk of '23.
Fully recharged several times in Aug/Sep '24.

Finally hit warranty replacement low voltage level 7/25.

So ya - not surprising you may eventually need one. Likely not low enough yet though.
Even when it gets that low - from other posters and myself - it'll start to get you to dealer to test it for warranty.
Voltage will need to be down around 11.6 to reach that level.

Good news - it appears if the spec'd batteries aren't in stock - you'll get an upgrade to the AGM the 25's came with.

There is more to deep sleep than just "the modem is turned off - that's it". The fact is that the vehicle is gasping for air by the time it goes into the deep sleep problem. An FLA or AGM battery should never be allowed to drop to a state of charge as low as what triggers the deep sleep problem. By repeatedly going that low it has set in course the destruction of the battery through sulfation. This poster states that he drives a significant distance and yet still goes into deep sleep. The person that posted the SSM on the ACCM module didn't also mention that that is for "some" vehicles that "may" exhibit problems. We are waiting for Ford's promised fix to enable the battery to be properly charged and to stop, permanently, the rapid battery discharge that everyone is seeing. The ACCM SSM was not "the" fix.

That's what Deep Sleep Mode is literally - modem is turned off. That is it.
You should really stop describing an issue by a symptom it causes - really doesn't help.
Issue is undercharged battery. That should be stated by everyone dealing with this to the dealer.

Indeed the voltage is low enough when that symptom shows up - damage is already done - and people have run for months in this state with truck starting.
Until they finally start it - go to dealer - and get a new battery.

Poster said nothing about deep sleep mode.
He said cabin lights are off - that's battery saver stuff that happens first.
Could have time to help the battery in this case.
Or help the battery die sooner to get replacement under warranty.

Ford promised no fix to the undercharging issue - gotta stop repeating that rumor.
I'd suggest a battery making it a year or two is hardly a "rapid battery discharge that everyone is seeing".
If an issue is exaggerated and the potential fixers know it - usually doesn't help.
Everyone needs to express the issue correctly when they go to dealer - and make sure it's on paperwork.
Not just "bad battery warranty replacement after customer receiving deep sleep mode".

It's just that I haven't had a single problem with it in the 22 months that I've owned it.
15,000 miles.
yes I think the battery is fine not just because it "starts" (it's a hybrid) but the headlights are bright, horn is strong etc with rhe key in the accessories position.
It's a small problem just an annoyance really to have a dark interior when you get in the vehicle.
But I don't understand the advice of charging the battery.
Aren't I charging it the hundred miles or so a day that I drive it?
How does an outside charger or a trickle charger do better than that?

Keep those headlights on in ACC mode for awhile - you'll perhaps see some other changes happen!
Do you use Fordpass app?

Why does your daily driving not charge enough?

No I don't use fordpass and I don't know what ACC means

Accessory key position you mentioned headlights were strong on.

You might help the situation a bit by causing Deep Sleep Mode to conserve a touch of battery, by disabling the modem that sends a report up to Ford's servers upon each turnoff.

Pull fuse 11 under the glove box.

The modem pings hourly to keep the network connection up - so truck can be reached remotely by Ford and by the Fordpass app - which you aren't using anyway.
It uses about 25 mA of power, so not much.
But it adds a process that could go haywire, especially if you have really bad/no ATT wireless signal where truck parks, and haywire could cause more drain that is not helping matters.

A "fix" to be provided by Ford certainly was not a "rumor". They made this known in a publicly released notice. They said that they would have a solution by the end of the first quarter of this year and then, when that came and went without that solution being announced, stated publicly that they would have the solution by the end of quarter two. That date came and went as well with no solution announced.

Then Ford released a partially related SSM notice that said "some" hybrid Maverick vehicles that "may" be having battery discharging leading to deep sleep "may" be helped by doing the ACCM software update. They did not state in that SSM that it was the "permanent" solution to ALL Maverick hybrid models from 2022 - 2025.

I had the ACCM update done and the battery SOC still reduces way too rapidly just sitting with the vehicle completely off. The repeated deep discharging of the battery, regardless of being an FLA or an AGM will shorten the life of the battery. On our third battery in two years and soon to be the fourth.

Those of us with this situation have a right to complain and demand action by Ford to fix it since almost one year ago Ford actually acknowledged this problem and, yes, they promised a solution to it.

Thank you for your response.

I spoke to the service dept at the Ford dealership and state issue as an uncharged battery. Service reps response was that it sounds like your going to need a new battery as the warranty is 3years/36 thousand miles (est $400)...Truck was bought in Jan 24 and has 58k on it...Not happy!

 

[Robert C]

I appreciate all your comments and advice but here's the thing.
What I'm saying is is this truck isn't left alone for any more than when I go to sleep to when I wake up in the morning so 8 hours and then at work another 8 hours I drive this truck all the time. I have never ever left this truck for more than 12 hours without driving it.
The battery has to be being charged.

From another post last week or further back.

That SSM that resulted in the ACCM software update - was the ONLY message Ford had about batteries and issues.

I challenge you to find anything else. You didn't last week, you won't now.

And that SSM prior to a solution - was ONLY about an intermittent battery drain issue.
That description has not changed, nor the process in it. Except now it says to update software.
Prior it said pat the customer on the back and tell them a solution is coming.

Too many people misunderstood that message INCLUDING dealers - accepted what the dealer told them about that SSM - and made up a rumor that Ford was working on a fix to an undercharged battery issue that finally resulted in Deep Sleep warnings.

Never true.

Not enough - that's the whole point.
Over 2 years of posts will help you appreciate it.

So my truck isn't charging by being constantly driven, it's not enough?, and yet the trickle charger should do it?

 

[RR - All the way]

So I have an EB and have never experienced all this sleep and battery crap. Seems a bit complicated to a simple person such as myself.

Thinking simply, is it possible that the OP hit the control towards the icon on the overhead panel and has selected the option for no overhead lights. Just sayin............

EB doesn't have these issues.

But good call on accidental light switch.
My son did that at campsite since doors opening/closing, next night I'm wondering why lights are not coming on after multi-day driving and full battery.
