If you are letting your car sit long enough that a bird can build a nest in it, you are going to have battery problems in any car. Since you don't drive it a lot, I would recommend starting the truck up every couple of weeks and let it idle for a few minutes. This will help keep the battery charged. Else, you could get a trickle charger to keep the 12V battery charged.

I know this doesn't resolve any past issues, but it might help prevent future issues.
This is partially inaccurate advice, starting interval is too long and a few minutes will not keep the battery charged.
You are correct that a trickle charge will eliminate the problem.

I have a 2024 Maverick, XL Hybrid, bought new (7/13/24) with just under 1 year of warranty left. A few months ago I Suddenly had start, and running problems. I see from this owners groups this is a known problem with battery issues. Mine got to the point it would hardly start, and most of the time it did start, it would then just shut off. I worried if I could drive it to the dealer to see about service, well I was scared I may loose power on the freeway, so I had it towed to the dealer I bought it from. I told them the problem. and that I had read the battery was a likely problem. My dealer, name withheld at this time, instead tried to tell me I needed a $9.000.00 wiring harness replacement due to "rodent damage" they gave me pictures to show this damage, however they were from so far away you couldn't see anything, and I do believe this was part of their scam. Anyhow there is no rodent damage to be found. I did have a bird trying to nest under the hood, and she kept dragging in straw to make her nest, but even me doing an inspection could see none of these rodent chewed wires.

Fearing a scam I had my truck towed to my personal mechanic who I do trust. He spent some time looking for "rodent damage", and all he could find was a battery that would not hold a charge, or start the truck. The battery was replaced, and viola the "rodent damage" went away. So now I am out of pocket for over $700.00 to replace a battery still under warranty, and a lot of man hours LOOKING for rodent damage that did NOT exist. The battery was used with a jumper station, and taken out and tested by them, and their battery company, and it has been found to be dead, and unable to hold a charge. I have kept the battery, and plan to allow the media to do independent testing to verify this. After talking to local news a few of them are pretty interested in a "Can you trust your car dealer" story

I spent over $29,000.00, on a truck I have not driven 5,000 miles yet, and had to buy at MY expense a new battery, because Ford puts cheap crap in their vehicles, and their representing dealers try to invent damage that isn't there, so their service department can make a big score.

I have also called the FORD complaint line, talked to a nice young Lady, who said someone would be contacting me right away about this. I can still hear the crickets chirping. A month, and no word from FORD. I can assure you, anyone that wants to hear my FORD experience is welcome to hear it, no lies just really bad service. I wouldn't suggest anyone buy a FORD product.

Wondering if this is typical?

These are pics the Ford dealer gave me of the "RODENT DAMAGE" there are several, at least you can see wiring in the 3 that I am posting here, most of them there are no wires in the shot at all. What there is are pieces of straw from the bird.

The following pics are from my mechanic, he either circled, or put an arrow to any wiring in the shot. There are several of them, and you cannot see any "rodent damage" in any of them, plus with detailed visual inspection by 2 of his best guys, they saw no damage, but after testing the battery they did find it to be dead, and it wouldn't hold a charge. New AGM battery made the rodent damage go away, amazing. Not sure what you call that where you live, but here in Ohio we call that fraud. Invented problem to sell a big money repair.

I loved this truck, then it had a problem. Had it been addressed properly, and professionally all would have been fine. After this fraud attempt I'm not real keen on the truck, even though it appears ok for now. My issue with the truck is how many $350.00 batteries do I need to buy, how often. Seems anything you may have saved in gas with the hybrid goes up in smoke with battery cost. I know one thing FORD isn't on my Christmas card list anymore, and that dealer could fall into a fiery chasm, and I would applaud.

I believe you got taken again by your trusted mechanic. It doesn't take two mechanics two hours to find rodent damage, maybe 5 minutes! A battery test would be the first thing to do given your symptoms and history. In addition, you ignored all the warning signs, which compounded the problem.

The simplest solution to the hybrids battery issues is a lithium swap. Boat guys long moved to 12v lithium alternatives, they work much better with infrequent charging.
The 12v charging system is not designed to work with a lithium battery, and is not good advice at all.

Right or wrong, kind of invited that diagnosis showing up with it full of hay and other material laying in the engine bay.

Edit: More I look at the pics, the more I am less likely to see the torches and pitchfork mob form on the dealership here. I can imagine a dealership tech that is getting paid maybe an hour at most warranty diag time that when he popped the hood and looked at that mess, made the somewhat lazy but not surprising call that it was rodent damage and did not want to wade through mouse piss and shit to find exact root cause. The $9K harness quote is a typical "go away" quote.

This post is looking like "Swiss cheese"...

He spend $700 on a NEW 12v battery??
The Hybrid 12v is a small one compared to the Eco's.
I plan on (preventative maintenance) replacing my Eco's AGM (with an exact match) in September. As it will be four years old in October.
MY Rangers' batteries lasted 4.5 - 5 years...
It will only cost me, $250 (exact match) and THATS from a local FORD dealer.. 😦

I’m pretty sure that $700 included all the towing and inspection fees

Most of which could have been avoided after the first need to jump start it. Calling AAA over months to jump start a vehicle is like putting electrical tape over the oil light on the dash. The problem is not fixed just disguised for the time being. Also since the OP says he called AAA multiple times they likely would not cover the towing for a dead battery.

This is where they dropped the $9,000.00 bomb, but I still have the text, just no idea how I could send it to this forum?
Open your text message, then briefly press the power button and volume down at the same time to take a screenshot. Or if you use Google Assistant, you can "Hey google" then say "take a screenshot". And if you have an ancient phone that has a physical home button, briefly press the volume down and home buttons at the same time.

Missing something here. If still in warranty why not return to dealer and work out an exchange?

My old F250 diesel has 2 batteries. Time passed since new. Wouldn’t start. Even after I tried charging. Towed to dealer. Dealer replaced them, I paying quite few $$. After few years same thing happened. I pulled them, return to dealer, parts department. Service mgr says you get new batteries, free of charge! I take it!!

Try again. That is nothing more than a warning to take precautions when using poison bait. I do. Because secondary poisoning is POSSIBLE. I want proof, not fake news and scare tactics. Your link states predators are "vulnerable" to secondary poisoning. Yeah, no sht. It also states "deaths associated with secondary poisoning is not well known". Exactly, that is basically what I already said. I have 5 dogs. I have no problems. So you don't need to worry and make up sht about me killing all kinds of other animals. Why did you buy a EB? Don't you know they produce way more, like 5 times more, toxic brake dust that ends up in the waterways and kills fish? Shame on you. Go protest the damn wind power that kills millions of birds (documented) every year. I quit the Nature Conservancy over their promotion of wind power as green energy. Nothing green about it. ☮

The 12v charging system is not designed to work with a lithium battery, and is not good advice at all.
12v lithium replacements are designed to work on AGM battery charging systems. How do you think they work in boats? Their have their own internal BMS that takes the AGM charging signal and uses it to charge the internal cells without requiring the host device to recognize the battery chemistry change.

Please do some research. The way the hybrids work, constantly trying to maintain 80% SoC on the 12v system, is a prime target for lithium tech. Lead Acid has been long abandoned in most sectors for a reason.
By name only. Some dealers are trustworthy and decent people. Many are not!
Nope. Ford works with dealers. If a dealer constantly provides poor business and Ford is not stepping in to correct them, they are just as much of a problem.

Ford needs to get a leash on their dealers and get them to behave. All automakers do, to some extent, but Ford has been slacking for a long time.

The simplest solution to the hybrids battery issues is a lithium swap. Boat guys long moved to 12v lithium alternatives, they work much better with infrequent charging.
12v lithium replacements come with a lot of caveats:

Upgrading a standard car battery to a 12V lithium iron phosphate (LiFePO₄) drop-in replacement offers massive weight savings, faster cranking, and a lifespan up to five times longer than lead-acid. However, you must manage alternator compatibility, under-hood heat limits, and freezing temperatures.

Critical Installation & Safety Factors
  • Built-in BMS: Always choose a battery featuring an internal Battery Management System (BMS) with short-circuit, over-discharge, and thermal protections.
  • Temperature Limits: Standard lithium batteries cannot safely accept a charge below 32°F (0°C). For daily drivers in cold climates, look for units with low-temp cutoff or integrated heating elements (such as the Ionic Lithium 12V Starter Battery).
  • Under-Hood Heat: Extreme engine bay heat can cause thermal stress. Some users prefer relocating large lithium blocks to the trunk if engine compartment temperatures routinely exceed maximum operating limits.
  • Alternator Matching: High-output alternators can overwork a drop-in lithium battery unless the BMS or a secondary DC-to-DC regulator limits the current draw.
The better and working solution for many (myself included) is to get an AGM battery replacement and do the BMS Reset after replacement.

Common 12V Issues & Deep Sleep
  • Parasitic Drain: Maverick Hybrids are known to enter "deep sleep mode" or suffer 12V drain due to connected modules or software bugs (such as the accessory/HVAC control modules failing to sleep properly).
  • Upgrades: Many owners replace the factory flooded 12V battery with an Absorbed Glass Mat (AGM) battery for better reserve capacity and resilience against phantom drains. Group 47 (H5) or Group 4 (H4) replacements are common options (though H5 may require minor tab modification).
  • BMS Reset: After changing the 12V battery, you must perform a Battery Monitoring System (BMS) reset (e.g., turning the ignition to on without starting, flashing high beams 5 times, and pressing the brake 3 times) to tell the truck's computer a new battery is installed
Be sure SSM-54785 is done to fix the battery drain issue.

Ford Special Service Message (SSM) 54785 is a software update released in April 2026 for 2022–2024 Ford Maverick Hybrid trucks. It addresses the chronic 12V battery drain and "deep sleep" or no-start conditions by reprogramming both the Anti-Lock Braking System (ABS) module and the Air Conditioning Control Module (ACCM).

Details of SSM 54785
  • Affected Vehicles: 2022, 2023, and 2024 Ford Maverick 2.5L Hybrids.
  • The Problem: Parasitic electrical draw leading to a discharged 12V battery and frequent deep-sleep warnings.
  • The Repair: Dealerships use the Ford Diagnosis Repair System (FDRS) to update software on the ABS module and the ACCM, test and fully charge the 12V battery, and reset the battery monitoring system.
