Been sitting since Christmas

[Hockeyfish11]

My Maverick has been sitting since Christmas in my garage (I’ve been in Florida). Two concerns with startup 1. 12v battery - assuming it will be a simple charge, and 2. Upper engine lubrication during start up. Assuming dip stick is at the halfway mark I was thinking of adding oil to the full mark and hoping it drips down and provides some upper engine lubrication. Your thoughts?

battery should have been put on a battery tender, but that's something you can do next time. deep discharge permanently reduces battery capacity. perhaps to the extent you'll be replacing that battery. that's a common issue with motorcycles and riding lawn mowers when you stop using them for the winter and it can definitely happen to your maverick also.

no need to do anything with oil.

you probably will get poor mpg after you start driving it again because the truck will know the fuel is old and run the ICE a lot to burn it up and get you to pump in fresh gas.

Turn the key or push the start button if it don’t start hopefully you have a jump box as far as the lubricant concern I personally wouldn’t fret over it although I would not rev the engine at startup

I don't know if the flood start procedure works on hybrids but if it does that would give the motor a pre lube before you actually start it

Procedure is to hold the gas pedal to the floor and keep it there while you press the start button or turn the key to engage the starter. The engine should crank over but not start as long as your don't release the gas pedal

the reason there's no concern about the oil is because it wasn't nearly long enough for significant degradation (through water absorption), and the top of the engine is irrelevant. Ford specified a 0w20 which no doubt will quickly drain down into the pan, except for whatever pooling might occur exactly as Ford engineers designed.

it doesn't matter if the truck is parked an 6 hours or 6 months, the same amount of oil will be on the top end (minimal) and the rest in the pan.

I personally throw an AGM friendly battery tender on anytime we are away or not using our Mav for a week...not necessary normally, unless we go on holiday. This rule is in effect for our camper van as well.

I have AGM batteries in both and even then our vehicles will slowly drain them and eventually kills the batteries due to parasitic drain. Then I don't have to reprogram everything like I do if I just disconnect the batteries.

I am not trying to hi-jack the thread with my following discovery, but when we were away on holiday if Feb of this year. I have been reading about all the battery drain issues/sleep notifications since before we ordered our 2025 Lariat. So before we left for a couple weeks I hooked up our maintenance charger to our truck. We were on a cruise in the South Pacific about 8 or 10 days away from home when I got an alert on my Ford App saying our Mav had gone into deep sleep mode. When we got home, I checked and yep, it had! Not because the battery had discharged over time but I imagine due to lack of use. All was good, batteries were fully charged on it so very happy. Disconnect charger, button up, check tire pressures etc, jump in and carry on just like normal.

So I imagine the OP may have had his battery saved from over discharging by going into sleep mode. But, I would recommend using an AGM appropriate charger when leaving the truck for any extended period. Hook it to the underhood connection points and save some money and aggravation in the long run.

Have a great day,

Yes - 14 days non-start it goes into Deep Sleep mode.
Deep Sleep mode is specifically disabling the telematics ability.
The telematics with no start/stop is merely pinging the network every hour to keep AT&T from dropping the connection - so you can reach it remotely. It's a spike of usage might as well not waste battery power on.
Long enough with battery going lower some Battery Saver features would likely kick in too, but about the only thing left if not using the truck, is it listening for the fob to unlock or get close enough, and haven't heard of anyone discovering that was disabled except the receiver on passenger door for keyless entry. Perhaps it eventually does disable the driver door one too.
So that would be the only extended drain left that could occur.
Long enough that would be a problem though.

Funny the manual mentions for storage some items that would not work together.
Start and run every 15 days. Ok - but the remote start just got disabled on day 14 with Deep Sleep, so...
Fresh oil change so no corrosives in oil sitting in engine - but then run every 15 days up to operating temp.

Much better with the tender.

Deep Sleep is not a design feature. It is a defect. A vehicle designed to be monitored and tracked remotely. And started remotely that is suddenly taken offline, due to the deep sleep problem, takes away features that owners paid for. Owners with 2023 Lariats did not come with a key fob remote start so the only way they can be remote started is through the Ford Pass app. If in deep sleep the Ford Pass app is effectively disabled and the vehicle is unreachable. Ford need to solve the deep sleep problem.

"...Ford need to solve the deep sleep problem..."

I am in the - they cheaped out on a substandard flooded cell battery camp. I think they can tweak the computer to be a little more conservative with the stored electrons while it sits unused.

This is a comparison of the original flooded cell battery and the AGM I put in over a month ago (at almost the same point in their life cycles - both batteries were close to the same age when the readings were done.

and an equal time before and after making the switch.

My truck went from immediate deep sleep after every drive to not one case since the change. I know time will tell but I am happy with what I see so far!

Okay, Zabsmav...i like to think about things and try to answer items like this while we await a fix...if it occurs.

Someone may have tried this, so let us all know...or try it and do the same!

Day 5, 7 or what have you, while away, go open your fard app....lock and unlock your doors for example...will this reset the sleep clock?

Or, do your own thing like maybe start it for a minute of 5 seconds on day 6, every day 6 and set a reminder on your calendar while away. This should keep your truck awake for your arrival home! Or wherever it is...

Just a thought on a possible "sleep" work around...it wouldn't hurt to try, would it?

Cheers, and i hope to hear how this works!

Then why has Ford added the 2025 hybrid Mavericks to the SSM that was published publicly on April 17, 2025? All 2025 hybrid Mavericks came with an AGM. The solution is not just putting an AGM in and calling it a day. Glad you are happy. But we paid a premium price for a Lariat model and expect all of our features to work as advertised. We loose vehicle tracking and remote start capability as well as have a dark vehicle when we get in it. They need to fix the deep sleep problem.

How do you propose that one goes into the FordPass app and do what you said when the app randomly reports the vehicle is now in deep sleep? It has nothing to do with a purported "clock" that puts it into deep sleep problem, it is the 12v battery randomly becoming so discharged that it shuts down all communication. Ford needs to redesign the charging circuit so that the battery gets fully charged in normal use just like vehicles have for years and years.

I don't disagree, and maybe I should have emphasized my second point as more of a acknowledgment that the battery drain still needs to be addressed. Trust me I am not happy about the fact that I had to buy a battery for 1 year old (Ford) truck, but the dealer did nothing (their fix lasted 1/2 a day - charge and reset). My time is worth more to me than chasing a problem I can fix (even if is only temporary).

I see the issue here, I am suggesting a simple (possible) solution for those that have to leave their truck for an extended period of time...where they would attach an appropriate charger for their particular battery before they leave.

This would not allow the battery to drain over time. In the OP's situation, I have suggested doing something to keep the trucks electronic systems active (such as locking or unlocking the doors or more likely, starting the truck for a minute or 5 every week or so).

This would keep it awake and eagerly anticipating the owners return with full lights and remote starting etc available.

This is only a possible solution (that I have not seen put forward to help others who may go away on holiday, etc))...NOT for a Mav that is having the dreaded deep sleep issues, such as yours seem to be experiencing where it sleeps whenever.

Okay, that should do it so have a good one.

[RR - All the way]

So is it bad to just take off a battery cable. My Camry manual says to disable battery if not using it for two weeks which I do if I am parked at an airport for very long......
