Endless repeated Hybrid failures have finally broken me

[MakinDoForNow]

I'm curious why you kept getting the impression it "limped to dealer on electric motor".

If anything, it was the opposite.
You probably limped to dealer WITHOUT the electric motor assisting.
The truck can travel only 2 to 3 miles without the gasoline engine running.

Truck would feel very sluggish on gas engine power only. Truck would be fairly zippy at low speeds with electric power only.

Just asking why you thought it was electric motor only. That only happens when you run out of gas.

The hybrid limp mode from what I have read is 2 cylinders active.

Don't do a dealer trade in. They will make thousands off you. Further adding to your loss. Sell on your own and buy a new vehicle without trading anything in.

How do you know all this?
I don't see where the OP posted the trade in he was offered.
I don't see if the state they're in removes trade ins from tax calculation.
We have no idea what it would sell for private sale since it'd be easy to search the service history and see all the issues.

That is an over temperature engine reduced power limp mode.

There's more than one limp mode.

So what happens is that the Check Engine light and Service Engine light pop on, and the engine continues to rev freely without a change in road speed. The truck maxes out at 35-40mph.

I'm guessing the engine is charging the battery, and the electric motor is immediately consuming the energy. But the coupling (damper clutch?) between the engine and electric motor has failed so the engine can't contribute to forward motion.

Just to recap, here's what's gone wrong with our 2022 Hybrid XLT in just the last ten months:

Codes P0811, P0E71, and PL920 at 41425 miles. Power loss on the highway, CEL on, limp to dealer on electric motor, damper clutch and flywheel replaced.

At 41725 miles, code P1061, CEL and Service Engine warning come up, limp to dealer on electric motor, got replacement engine.

At 49174 miles, code P1061, CEL and Service Engine warning lights, limp 20 miles to dealer on electric motor, new "trans" installed and damper clutch replaced again.

Now at 51k miles, waiting for codes to be read, but CEL and Service Engine warning lights illuminated with limp down highway to out of state dealer. Was unable to get loaner on a Saturday, messed up trip, blah blah blah.

Wife says dump it. I hate giving up a paid off vehicle before the factory warranty has even run out, but even I don't trust it anymore.

Hate to say it but it seems like a lemon. Perhaps the only good thing is everything is everything is almost been replaced

F-that.
dump that POS.
Musta been a Monday truck.
No problems with my 22 HYB XLT
Sorry about yours...

I understand your symptom.
It's in a "limp mode" is the bottom line.

But the assumption of what is going on may be incorrect.

What you "think" is happening sounds like normal operation for reverse. But it's behaving the same way traveling forward.

I of course can't say for sure without being there.

2024 with 26000 miles no problems yet. I am a light foot driver n rarely push throttle beyond 30%

Driving behind Lightfoot Larry's can be frustrating

Unfortunately the 1st year of a new vehicle is often plagued with problems. Not always though.

see if the dealer will do a trade in - get something else - you'd have a hard time selling this on your own if you chose to divulge what has been fixed so far, maybe the dealer will be a little helpful. Doesn't hurt to try.

yep - my 22 w/ 30k miles has had 0 probs except for a CV replacement.

My opinion...You know why it's called the top 10 percent? Because 90 percent didn't make it...Point is, mechanics same..Each one may have the same certs but that really means nothing when it comes to the caliber of experience, knowledge, and work ethic plus the specific dealership management protocols...I try to build a relationship with the service writer and find out which mechanic works on the owner's vehicles..That who I want..

There is no coupling or damper clutch.

Inside of the transmission, there’s 1) a traction motor, that uses electricity to make torque to create forward movement and there is 2) a generator motor that creates drag on the planetary carrier in the transmission to change the gear ratio of the continuously variable transmission, thereby generating electricity that gets sent to the high voltage battery, the traction motor, or both, depending on what the BMS tells it to do. And 3) a planetary gear set that serves as the continuously variable transmission. As you can see from diagrams below, there are multiple combinations of where you send engine power and what gear is connected to the traction motor and what gear is attached to the generator motor. iirc, the Maverick has the generator attached to the planetary carrier.

If the generator motor, is freewheeling, the planetary carrier is also freewheeling, which means there is no power being sent from sun gear to ring gear and the truck will set at a stop. When you want to go forward and give it some throttle, the engine will rev up and the generator motor starts generating electricity, which creates drag on the planetary carrier, which slows it down, which increases the gear ratio of the transmission, to go faster and faster. So let’s say your engine is making 50 hp and the generator motor is using 20 hp of that output. That will result in 30 hp going though the transmission epicyclic gears: sun gear, planetary gears, planetary carrier, ring gear and out of the transmissions at the output shaft. The other 20 hp of generator drag that is being used to change the gear ratio of the transmission is simultaneously getting converted into electricity, which then drives the traction motor, which is also attached to the output shaft of the transmission.

So when you describe the engine freely revving and the truck barely moving, that sounds like the generator motor, or it’s associated electronics, has failed and it is not making much drag on the planetary carrier, which means the the planetary is nearly freewheeling, which means there is minimal power from the gas engine getting from the sun gear to the ring gear to drive the transmission output.

I liked my ecoboost engine that I understand and for its quickness . regular 8 speed tranny as well . it worked well for me .
