Late 2023 build hybrid shudder

[Mxer97]

Anyone with a 23’ that was built toward the end of the production for the year, having the shudder on decel when it goes from ice to electric? I believe mine was built late August 23’. I saw a Tsb, but it seems it was for the earlierbuilds

No shudder. Yet.

How many miles do you have on yours?

Are you talking about shudder, or an occasional thunk (like dropping the clutch on a manual)? I've had the thunk happen a few times when slowing to a stop from highway speeds, usually down hill. I don't know what it is though. I have manufacture date of 7/23.

Yep, mine did a sort of rumble strip shudder during braking a month ago. I glanced down and saw the ICE hadn't warmed up much and assumed it was a rough coordination event between the engine, and eCVT. Hasn't done it since. Mine is a 9/23 build.

On a related noted; I have noticed the ICE can have a quite a lumpy "cold high idle" when the PCM decides to start it, to charge the HV battery. Also causes some surging while warming up--feels like someone has tapped the truck from behind. Also, if the ICE hasn't been running and up to temp, there can be a hesitation from a stop, from when you stab the throttle and the ICE shows up for work.

Yep this happens to me randomly. I believe it’s due to slowing and the ICE turning off an in inopportune time combined with braking etc.

I've seen a couple posts with this issue, and the only one that claimed to get it fixed said the dealer replaced his high voltage battery I think. I'm not completely sure I buy that, and I'm hoping someone else will post with a different solution. I would link that post I saw, but I can't find it. I don't want to deal with monkeying around at the dealer if I can help it.

yea, it’s the rumble strip shudder! It has happened a few times coincidentally going down an incline on the brakes getting ready to pull out of the driveway from work in the afternoons. Maybe another random time not long after the initial start up. So I believe maybe “not up to temp” has to do with it.

Fwiw, my truck has always done it after it was well warmed up. I had probably been in the road for an hour or more.

Hope those that need it saw the early post, since reference to TSB was made above, hope others that have the issue in right MY caught that part - the fix.

From reading that and observing the motors' RPM and direction while driving - I need to either pay more attention or look at some current log files.
I'm wondering about smoothness of the Generator motor spinning up the engine 1 direction and then needing to reverse itself for correct gearing ratio so fast when already moving and the engine power is brought in, or thinking it may need to move.
Sort of how a starter gearing can sound when it doesn't get back out of the way when the engine has turned on.
Not sure the Generator motor RPM needed to get the engine on, but that is one direction, and then it needs to reverse so the correct power from the engine is used for the needs at the moment.

Thinking of the other described braking/slowing effect at higher speeds when engine is shut off - I wonder if the engine is shut off and then the desired motor RPM is called for, so for a brief moment a bad mismatch.

Thinking of how some HVAC air handler motors start to go clunk when they just are turned off. Never mind they aren't reversing.

My 24 has done it a couple of times. If I am remembering correctly, it's usually when the ICE is cold, and it shuts off coming up to the first stop or two. It hasn't really worried me because the truck seems to do some unusual things once in a while when it's cold like surging while stopped and the ICE is warming up and occasionally a poor hand off from regenerative braking to the brake pads causing grabby brakes.

Mine did this until I had the damper replaced. Involved removing engine and transmission. Also got rid of rough and loud idle on cold starts.

Yes same issue with our late 2023. Ford needs to step up and fix these issues. This hybrid drive train is a throw away after about 80,000 miles. They will tell you that you will need a new clutch which requires removal of the engine at the tune of $6000.00 Also if you think your extended warranty is going to save you think again. Ford will tell you that it is not covered because its a wear item. Total dam rip-off!! Never again will I own a Ford Product.

Maybe, you just don't know much about Ford Hybrids, and confusing them with cars that use a conventional crap CVT transmission? Fords use the same type as Toyota, and are damn near bullet proof. They are notoriously quite reliable for the most part, many in the 200-400K range running around out there. The problem isn't getting Ford to fix them, as much as it is getting Ford to witness the actual problem. The 2 most recent people that I'm aware of that the dealer saw the problem, had the problem resolved. The issue in the latest I've seen turned out to be the battery(which Ford promptly replaced under warranty). The hybrid power train components are also covered for 100K miles. The other ones with similar issues caused by a bad damper also had them replaced under warranty. Where's the total damn rip-off happening again?

What are you talking about? The hybrid power train is total crap! Loss of power issues all over this forum.

It's like 1 in 25,000 units.
