Mine's been broken for 2 years, now it's a two-wheel drive. Jerky acceleration but it goes
Are you not on the recall list??? If not, be patient, cuz I'm pretty sure this whole PTU thing is going to snowball into possibly something much bigger before it's all said and done...🤔😉😁
 
A reasonably good article about the PTU issue. This forum even gets mentioned! Be careful what you say... ;)

The diagram in that article puts it into perspective. I also found this video on youtube where a guy pulled his PTU, and you can see where the input spline is, an that's where the snap ring is. Holy hell.

Now I can REALLY see how this is not a 4L or 4Hi issue. (visual learner) Dodgeboy mentioned inspecting the PTU for damage, how do you go about that? I figure, crawl under the vehicle and start wiggling on drive shafts for excessive play or something, but I don't even know what's normal, or even if that's the right away to go about it.

EDIT:
For what it's worth, I just called my local jeep service center. What I could find out on the phone is there is a "Stop Sale" order out until the recall is resolved, but not a "Stop driving" order. So, and I'm paraphrasing, "so long as I'm driving normally and i don't get a stop driving letter I should be good".

Other than that, my local service center didn't know anything else that you can't find online somewhere.

As an aside, i'm one of those guys who's super anal retentive about my equipment, and this is gonna eat at me until its fixed. sigh

Stop Sale of what?
AD2 PTUs?

Jeep is not making and selling New Cherokees, so it’s not that. Edit I did a search and I am incorrect unbelievably there are still new KL Cherokees left from 2023 MY for sale at Jeep dealers,that is crazy

Used Cherokees on Dealer Lots?

There are TWO recalls. The "Stop Sale" order is on the second, 25E-003. That order stops the replacement of PTUs with the affected part numbers and puts you in line if you had your PTU replaced with a defective one identified in the recall.

If you look around, you can find brand-new 2022 and 2023 KL's sitting on the dealer lots. They aren't used, just unsold.

Thanks. So it’s similar to how they handled the spline issue with W47 and W48 was specific to replace a failed PTU with a new version if not already replaced. They will just determine their next step with these new recalls.
Yes I added for correction right after I posted that I found new 23 KLs for sale at dealers and was super surprised, cause there are none available at Jeep dealers by me
 
Fair enough.

The FCA US LLC Chronology (in the links above) shows that Recall W47 (Recall ID 20V-343), Recall 45A (NHTSA Recall ID 23V-302), and the current recalls are all related.

From Recall W47:

The PTU on about 67,240 of the above vehicles may have been built to allow relative movement between the differential input splines and the transmission output shaft. This condition may result in the teeth of the input splines wearing off, which may eventually cause a loss of engagement between the transmission and the differential inside the PTU. If this occurs, torque cannot be transferred between the front wheels and the transmission, which will result in a loss of motive power while the vehicle is in motion and a loss of the PARK function while stationary. A loss of motive power or PARK function can cause a vehicle crash without prior warning and/or injury to others outside the vehicle.

I believe what that means is because the KL is mainly a FWD vehicle it will transition from 4x4 to FWD as conditions warrant. When you are cruising down the road you are likely in FWD mode only. If the input splines shear, you no longer have FWD but the computer keeps trying. Your car doesn't "know" it is free-wheeling, but that's exactly what is happening. You have lost "motive power", potentially at high freeway speeds. If you pull over and put the transmission in PARK, it will not prevent the vehicle from rolling away. BUT the rear drive is still available, either in 4hi or 4lo. So the "fix" in w47 was:

Reprogram the affected vehicles with software for the Drive Train Control Module (DTCM) and the Electric Park Brake (EPB) that will maintain vehicle propulsion by engaging rear wheel drive function and prevent rolling in the PARK selection by activating the electric park brake if a failed input spline occurs.

So when the PTU pukes, you can at least get off the road. Once stopped and in PARK, the emergency brake will come on to make sure your car doesn't roll away.

Can you prevent it? I don't think so because this is a defect that has been traced to an improperly installed snap ring. From the recent recall notice 01C:

Some of the above vehicles may have been built with an improperly seated input shaft snap ring in the two-speed Power Transfer Unit (PTU). An input shaft snap ring that is not fully seated may allow uncontrolled movement of the input shaft inward. Uncontrolled movement leads to the potential for wear to the range shift sleeve, spline damage, and / or range fork damage which can cause an unexpected loss of motive power or loss of PARK function while stationary. Customers may notice a Service 4WD message, noise, vibration or change in drive quality. A loss of motive power can cause a vehicle crash without prior warning. A loss of PARK function can cause a vehicle crash without prior warning and/or injury to others outside the vehicle.

This isn't a 4hi vs 4lo issue. You may not even know it's happening unless you notice "Service 4WD message, noise, vibration or change in drive quality". The recall says "may notice", so "maybe not"! I don't think there is anything you can do to prevent it, except maybe pray.

I don't know if this relates to your experiences in 4lo or not. I somewhat doubt it. Maybe others can chime in.

Hope this helps. Let us know! Maybe someone else can take a crack at the issue.
Mine was not 4wheel capable I had 3.2 l 6valve. With the 9 speed transmission. Mine would randomly shift from park into gear. Thought I was losing my mind but on the third and final wreck entire dash blinked loss total power doing 65 ran into an abandoned car on side of highway spun back into middle of highway looking at car coming directly to me. Mine was 2015. But the same ptu. Mine had the recall to reprogram the emergency brake but that didn't fix the issue it continued to do as what could happen. Mine had everything that could happen , happpened.

"not 4wheel capable" is Front Wheel Drive (FWD). Unless you have a 4WD selector (ADI or ADII), more specifically a 4WD Low selector (ADII or ADII Lock), you are not impacted by the recall. In fact, if you really are FWD, you have no PTU!

There is no failure I'm aware of that would shift the transmission from Park into gear. That's really strange.

But, it looks like maybe you had the W47 recall, since you "had the recall to reprogram the emergency brake". That means you have an ADII PTU with 4WD and 4WD Low. That recall did two things, 1st it reprogrammed the DTCM to maintain forward propulsion if the input splines shear. 2nd, it would automatically engage the parking brake if the splines sheared AND you put the car in Park. That doesn't sound like your failures.

So I think what @osimj is trying to say, is, WTF?????
 
My 2019 TH is somehow not included in the recall even though I'm on my 2nd PTU now. :mad: Was really hoping it would be on the list and that I might have a chance of getting reimbursed for the last time my PTU blew up.
10-11-16 to 2-20-2019 are the effected dates for the new recall.
What is your build date ? If it’s not in this timeframe that answers your question
 
Might be on record you have a newer PTU that is not affected too. Interesting this recall might have nothing to do with failed PTUs?
It is the PTU.

copied from link that will be below

The issue is linked to an improperly seated input shaft snap ring in the PTU. This flaw could allow uncontrolled movement of the input shaft, leading to damage in key components such as the range shift sleeve, splines, and range fork. These failures could cause the vehicle to lose motive power or its ability to stay in park, increasing the risk of accidents or injury.

Remember there are TWO recalls. One for KLs with ADIIs that were built in the range, and one for ANY PTU of certain P/Ns that may have been used as replacements. There is no time range for the 2nd recall.

Yes I forgot about that ,both those part numbers on the other recall 68333255AA and 68307403AC are 2 speed PTUs 😎. So Firehawk989’s first PTU evidently wasn’t one and maybe their replacement isn’t one of those numbers and they won’t be on the list, or it will take time to determine that if their second one fails.
 
My 2018 TH is on the recall list. It currently just pops out of all forward gears. The dealer put a new transmission control module in it and said it was fixed, just for it to do it again on the way home. They are now replacing the ptu. I don’t understand how they can have a recall without a fix………,,
