Sounds wrong, very wrong. Try sports mode, if it’s not very noticeable difference in acceleration I would guess a bad wire. If it is noticeable but short lived then poor battery.
There are tools and phone apps that will show cell performance and overall battery ‘health’ dealership and Ford has even better tools but would have no desire to admit unhealthy battery
Oh in sports mode? It runs like a bat out of hell! But hybrid mode isn't used in Sports mode, correct? And I get about the same mileage when on the highway (65-70mph) no matter what mode I'm in.

Question, is the electric motor supposed to be working along with the gas engine when in hybrid mode? I get the feeling that it isn't.

In sports mode it accelerates like a bat out of hell. But the mileage it about the same no matter what mode I am in. I try to remember to switch it to econ every time I start it up. But it doesn't make much difference in mileage.

What does the truck computer say your mpg? Is it pretty close? Mine typically 1-2 mpg higher than what calculated by hand.

Not sure what you mean by hybrid mode, but yes a parallel hybrid system generally has the electric motor helping as long as there is enough battery charge.

Yeah truck computer shows a bit more than the actual mileage, when calculated by hand. I have about 3500 miles on the truck and have NEVER calculated more than 32MPG

I don't get it. I am only averaging 30mpg in my hybrid Maverick. That is 40% town, and 60% highway driving. IF I drive all in town, I average 20-22 mpg. This is done by actual math at the pump, not by the trucks estimate. Here's the thing, I BARELY touch my accelerator pedal, and I can stay in electric up to about 20mph. After that it kicks on the gas engine. When I say barely I mean it takes me two blocks to get up to 20. Now, also, if I am looking at my instant mileage, it NEVER shows more than 8-20 mpg at low speeds but accelerating with the gas engine on. Then I get up to speed speed and back off the pedal to put in in hybrid mode. On the highway I will regularly get 35-38 mph indicated on instant mileage.
Here's my thought and question. When the gas engine cuts in at low speeds (30mph) doesn't the electric motor keep assisting the gas engine? I can't figure out how in the world people are getting over 40mpg.. My truck just doesn't seem to have any power in electric operation.
Before you start thinking I am driving crazy, I'm 66 years old and being passed by other cars all day long. I brake easy and accelerate lightly, backing off the gas pedal to let it kick into hybrid as much as possible.
Bad battery? Bad programming? Bad electrical connection somewhere? Anybody have any ideas? Took it to the dealer, they drove it on the highway and said "It's getting 35 mpg, what do you want?" Well, the big problem isn't on the highway, it's on the damn city streets at sub 40mph speeds!
Or is this just all I can expect? Yeah I'm frustrated. And yes I know how to drive a hybrid.
I improved my city driving mpg after disappointing results by mostly %power usage gage at 9-18% as less takes too long. (this is my first 6kmiles in hybrid so I'm just learning). Too slow accelerating is worse than a reasonably fast acceleration particularly if driving to keep in battery mode once you are up to 20-30-40 just get to speed while keeping power gage under 20%. If you can get get 90+% recovery when braking then getting back to speed is pretty much a wash. Also when I first leave and truck is cold I will put truck in drive economy and low. My thinking is the Regen braking is enhanced ( if in EconDriveLow more current is put into battery when foot comes off accelerator, at 35 Regen can go to 100%. I trust computer to max Regen to capacity to what is safe to put into battery. This will help warm battery internals quicker which will allow max Regen current acceptance. The warmer the battery the more current it can accept or disperse. The computer will adjust transfer rates to whatever Ford has programmed. I generally do not leave truck in low for more than 2 miles. You can push the L button on and off at any speed. If the HVB gets close to being charged the ice will be used to engine brake instead of Regen braking as fully. This will happen if you forgot to turn low off. After a mile or so in EconDriveLow I have a 14 mile trip that's winding 40mph with 6 90° turns so driving is 10mph to 40mph. Depending of ??? I usually get 42-60 mpg. I normally don't super attempt to keep truck in battery mode as I just keep the power gage in the 9-20%range. If the Regen braking seems to not be as aggressive I may turn drive low on for a few minutes. You cannot leave low on for extended periods or milage will go downhill. When approaching a 90° turn I sometimes will turn on low at 45-50mpg and 100% Regen brake to speed I want to make the turn at and then gently touch the accelerator the turn low off or maybe not. Have fun but try driving a little more aggressively.

Thanks for the advice. I'll give using the L button a shot. But understand, in no way can I ever go beyond 10% power usage without the gas engine starting. Then instant mileage starts at 10mpg at 20mph, and slowly increases to maybe 22mpg until I let off the gas to put it into electric. Then on the highway at 65-70 it will start out showing 30mpg and slowly get up to 35 on level ground after maybe 10 miles. I have never SEEN 40 mpg except on a long downhill.when it might flick up to 45 for a bit close to the bottom of the hill.

I agree with poster about babying the Maverick hybrid is counter productive. Coming from Prius I got the wrong view on how good mileage is achieved by hybrids.
My wrong view was wimpy driving is forced on Prius to get mileage numbers. The real reason was small ICE small electric motors and a battery with current limits on charge and discharge rates.
Ford took another route Larger than standard sized engine (2.5 v 2.0 eco ) much stronger electric motors and a battery chemical with high charge and discharge current rates.
But gets around Prius rates with lack of proper shape factored.
So, my new view is its engineered to be at the sweet spot with normal driving.
Trucks are always over powered when used as a daily driver.

Still think something is wrong with OPs truck. In most conditions my truck will climb and stay in electric mode to 35mph and can stay running a steady 30mph in electric mode for about 8/10s of a mile. In limited times / distances with 45 mph can be managed after brief pass into hybrid mode. Even in rolling 50 mph zone it will try electric mode for at least 1/10th mile at a time.

I accelerate at a pretty brisk pace, then feather it to keep it in electric at speed. Have been averaging around 42, but this last rank ran with no climate control on and hit 49.
It seems counter intuitive, but try accelerating faster and save the battery for when you hit the speed limit

Try driving some in all gears and modes. Might help the computer to build some tables (give the computer some data to possibly work with). Remember it says that the truck may do strange things for some time at first. The program might be turning some things on and off to see what does what and when and at what voltage or resistance. I have never bothered to find the instant milage screen, I need to see what it's like. Perhaps when you are seeing 22 mpg on that screen it's simply showing that the portion of the torque being used from the ice to push the truck equates to 22 mpg with the rest of the torque being used to generate the electricity for the electric drive motor which may be factored in differently. I'm going to have to find the instant screen. I drove 1.8 miles the other day and my trip summary showed 1.2 electric with a trip mpg of 84.6. I would expect the 22 mpg or whatever you are seeing is only for the mpg for what the truck actually did. I have trouble hearing the ice run due to lariat sound deadening windshield and ears ringing but it seems to come on sooner than I would like. I was thinking 12-15% on mine but do not worry about all electric mode since all the electricity was created by the ice. The computer will try to run the ice at it's most efficient rpm's for the energy needed. If any generated is not needed it will be put into battery for future use

Yes accelerate using up to 20-22% power then feather it.

sounds like you battery capacity is really low or its not charging well. a drain or short may be leaving you hybrid battery low to start every time as well. are you city trips short? might be able to test this with extended city driving.

My hybrid is doing the same thing and I also drive it like a baby. Only getting low 30’s and I noticed it after the recall was done but may just be a coincidence. Does everyone use 87 octane or higher?
