7 Days Parked at the Airport - Here's What Happened to the Hybrid Maverick (Battery)

[Leuf]

A quick question. Is your battery an AGM?

Yes. And it's apparently gotten worse because I drove it for a half hour 9 hours ago and the lights didn't come on just now. That's ridiculous.

I've heard so many people talk about the 12V battery issue with their Maverick so I wanted to share my results.

I drove to the airport and left my 2024 Hybrid Maverick parked their for 7 days. When I returned, I unlocked it and it started up with no problems. The only difference I noticed was the MPG for the trip home was 33.9 whereas my avg is 46.9 and this trip would have been about 45 MPG given it was mostly highway with no traffic. I believe the reason for lower MPG was due to the gas engine running throughout the trip home to recharge both the Hybrid and 12V battery given that it was parked for a week.

All in all, I can say that if you have a good battery, you shouldn't have any problems with your Maverick being parked for days. All of this talk about keeping the 12V battery charged while the vehicle is parked for days is overhyped. If the battery is good, it should be just fine. I received my Maverick in Dec of 2023, and never had any issues with my battery and never need to replace it. Those who did, probably had a faulty battery installed during production.

It's not a battery problem. It's an intermittent drain that Ford has acknowledged. Mine has been fine then all the sudden got deep sleep notification after a decent drive !

There is 0 excuse for people with 2ish year old cars to be dealing with battery issues .

The lower MPG on the return trip was due to colder temperatures, headwinds, higher speed, or a combination of all three.

It was NOT due to the status of your HV battery or 12 volt battery.

I am 100% sure.

The HV battery is SMALL. Very small.
The 12 volt battery is small too.
You did not say how long your trip home was, but I promise you, with certainty, your HV battery is fully recharged in the first 3 to 4 minutes of engine run time. (I have a ScanGauge and this charging process is consistent, over hundreds of cycles.)

I your trip home was less then 4 minutes, then I'm willing to entertain your wild theory.

Second, while the 12v battery does lose charge while just sitting, it takes a TRIVIAL amount of energy to recharge it, and it usually recharges very slowly over HOURS.

In reality, it takes trivial gasoline to recharge either, or both batteries. Too small to notice. Unless you did a really short, 2 mile / 4 minute trip. Then you MAY notice a low "trip" MPG, but your overall tank MPG would be immeasurably affected.

My trip home was 21 miles and it took me about 25 mins to get home. It was midnight and the temp was about 20 degrees. Mostly highway with no traffic. Thanks for the info. I just guessed the lower MPG on the trip home was due to the HV and 12V battery being charged because I usually get between 44-50 MPG per trip to and from work everyday. It’s a 20 mile drive equally shared 10 highway and 10 city with stop and go traffic.

Thx for sharing. I think this site has alot of complainers lol. Almost 3 years with our maverick and no issues, other than 2 softwear recalls.

My ‘22 hybrid has always started and only the driver side door unlocks by grabbing the door handle. Passenger side door doesn’t open when in deep sleep mode when you grab the handle, and interior dome lights don’t work.
Question: if I delete Ford app from my phone, will this solve the problem?
Thanks!

I don't think there is a problem. My truck will be 3 years old in March, and does exactly what your truck is doing. It goes into sleep mode, and shuts down things that will drain the 12 volt battery, but retains power to start when I hit the start button. (Lariat) All the items that shut down turn back on without any problems. That's the way Ford designed it to work.

I would tend to agree that a hybrid battery or regular 12V battery should not drop in voltage significantly in a week of non-running, even two. MPG is highly affected these days by tires and proper tire pressure + road conditions (wet roar, wind)

IF alternator was producing 500 A it would equal to about 7 kW which is a bit over 9 hp. Maverick will likely have something like 175 - 200 A alternator, so yes, it can affect the fuel economy, but not that much IMHO

My truck, when not in 'deep sleep mode', will turn on the interior dome light when I open the door, that's the way it's suppose to work. You should never have to get into a 'dark' vehicle and have the lights turn on 'after' you hit the start button.

RE: Only driver's door unlocks = I believe that is the default setting for safety - the other doors remain locked so someone lurking, a car jacker, can't get in when you unlock the door.

I know on my other vehicles I can change the setting regarding which doors remain locked when you use the proximity touch feature. Look for this in the owner's manual.

I am like....who cares????????? As long as the truck starts up faithfully every time, regardless of how long it could be sitting all by its lonesome self. If the app wants to tell me its in deep sleep, fine...I can still start up using the key fob. As always, the truck takes me wherever I need to go.

Who cares! I paid for a vehicle for a purpose not for a failure and inconvenience. I have a 2024 and 6months in it started the battery BS. Dome lights first so I can't see the freaking key at night. Now radio doesn't work when stopping and sitting for a minute before work! Recently now key fob doesn't always work, so I manually open doors. I have been watching battery voltage and it has slowly been going down closer to 11 volts. It is slowly being destroyed and sulfate. They have had years to figure this out in the Escape. I'll be damned if I have to drive the vehicle at high speeds to " refresh "/ charge the battery or trickle charge when I drive almost everyday. I've been bringing it back to the dealer every 2 weeks. I will cost them time and money. This is what everyone should be doing. Built Ford TERD.

Why would the hybrid battery drain that much in just a week though? That doesn't seem quite right. I know with my Prius I've parked if for over a week and have never noticed any appreciable drain on the traction battery.

It’s believed that the modem continues to communicate over the Internet. There may be some other things going on in the background as well, but I’m not sure of.

 

[Angloblaxon]

Not helpful but I found my car doesn't draw if the alarm isn't armed. Once I lock my car... the battery will be dead in a day.

I could see that draining the 12v battery, but not the traction battery.

Anyway, I hope for the best when I finally get my Maverick (just went into production). I'll have to keep some of these things in mind, especially since my conditions are challenging being2 miles from work, so frequent short trips in winter with temperatures that can drop subzero (and sometimes double digit subzero, not windchill, straight temps). So far I've had no 12v or traction battery issues in my Prius, but it seems 12v loads just keep increasing on modern cars without sufficient consideration by manufacturers to whether the 12v battery can actually handle those loads.

I appreciate the post and happy you are not having any issues. We have a 23 Maverick that we received in Aug of 23. We are on our 3rd ford battery from the dealership. It is currently at the dealership now, probably getting its 4th battery. I really don't know what the chances of us getting 3 bad batteries in a row are, but I know there are others that are having similar issues.

Correct. But, when my truck is not in 'deep sleep mode', you can grab the passenger door handle and it will unlock if you have the key fob on your person. When my truck is in 'deep sleep mode' then I must use the key fob and unlock my truck if I want to access the passenger side door to open.

 

[NewcMaverick]

We've gone on multiple 10 day trips with our Maverick sitting in the Economy lots at O'hare. I never even once thought about the thing not starting lol. It started up and worked great every time.
