Hi I've worked at Trenton Engine for 38 + Years and never Remember seeing multiple vendors used on a Small Simple Part such as a C-Clip at the Same Time !
The PTUs are not manufactured in the Trenton Engine plant , they are manufactured by AAM . AAM manufacturers lots of parts and may even make their own C-Clips (Snaprings)but that’s doubtful. So no one knows where the C-Clips (Snaprings) come from or if there are multiple sources.
 
How long will it take to “develop” this remedy? I mean it’s been months and looks like no end in sight.
In the US, the PTU itself may never be fixed. The NHTSA allows 3 options to address a recall, repair, replacement, or refund. I addressed my opinion of each option here:


Recalls appear to have no time limits for the "fix". And how Stellantis will handle this world-wide? Who knows??? They aren't exactly swimming in cash at the moment.
 
Yes this has been talked about they (AAM American Axle and Manufacturing) are US based but have plants around the world .
Headquarters is right here in Michigan, I used to do balancing work for them at an old job.
Well, they need to get off their effing a$$es, where they've been for the last 10+ years, and finally get with the program then, no???🤔🫤😉😁

Well I’m adding this since my brain wasn’t remembering that we also used AAM U-Joints in the driveshafts that our shop built . I did not work in the Driveshaft build area, so it slipped my mind.
well since they make U-Joints and CV Joints they must make the snap rings too.
BUT the problem ISNT the snap rings themselves it’s supposedly improper installation of it. 😎

There's also a question of how much of NHTSA exists anymore. Elon famously hates them due to investigations into Tesla driving aids and recalls. Tesla investigations and the NHTSA were one of the first on the chopping block. So regardless of what the rules are regarding recall and fix, there's likely nobody left at NHTSA for enforcement.

And with Stellantis immediately idling plants and laying off workers (likely anticipating reduced demand), the chances of them retooling or spending money with AAM that they don't have to is approximately zero.
 
"Improperly installed" could mean a lot of things. It could be that the snap ring COULD NOT BE properly installed due to a design/manufacturing error.

That would still constitute "Improperly installed" but would not be installer error. IMO

I still want to know if the groove could simply be relocated or deepened, or a different style ring is necessary.

Can you imagine if they're manufactured in China?

  • PTU exorbitant price before: $2,800
  • PTU post-April2 exorbitant price plus tariff: :eek:

OK. This is going into the political side of things, but NHTSA had 30 employees cut under DOGE. Let's look at the employment numbers. In FY 2023 they had about 675 employees. In FY 2024 they had about 800. That's about an 18% growth in one year. Then this year, they laid off 30. That's 3.75%. Really? "Nobody left at NHTSA for enforcement"? By my math, there are still 770 employees left at NHTSA, 95 more than in 2023. AND, what they cut was largely a duplication with IIHS testing. That's hardly a "cut", more like "stop the wasteful redundancy".

I'll agree that Stellantis is idling plants and laying off workers. If you don't sell the product, you can't employ people. Basic business sense at the customer's (our) expense.

But please, don't make a mountain out of waste, fraud, and abuse. At least that's my opinion.
 
Wow, Stellantis engineers sucked in 2017 and that's Elon's fault today. Get a grip.
Where was it said that Elon contributed to the PTU issue?? :unsure:

Correct Trenton did Not Have Any Thing to do With the Making of PTU's.
However the Trenton Plant had Made MILLIONS of Engines and I was here for 38 Years Making Them.
I Seriously Doubt if they would Bother to Make Simple Generic Part as a C-Clip !
Better Quality & Price Could be Easily Had From a Hardware Manufactuer !
Hi It's Real Simple Parts (Nuts, Bolts, Washers, Clips) are Generally Singled Sourced.... And Yes the are Exsisting Doomsday Plans for other Sources. Factories Do Burn Down.
This Situtation Sounds Like a Failure in Process & Quality Control.
 
"SVC 4WD" has been on for two years now. Makes it through inspection so it's two wheel drive until I get a recall or sell it.
I thought that too. We only use my wife's TH on road. The dealer and the importer (New Zealand) both said it was likely an electrical fault, so the car would be safe to use in 2WD until Stellantis came up with a solution.

Which was all very well until it failed. Lost power when we were driving to work.

The court system here in New Zealand is now the direction we are going. The Motor Vehicle Disputes Tribunal.

I know I’m correct , you didn’t have to tell me.
And if you want to talk about quality control, your Trenton plant had a problem with that for some of the 3.3 and 3.8 crankshafts not being balanced correctly at your plant and the place I worked at had to manually rebalance them and send them back to Trenton or scrap the ones that weren’t fixable.
So it appears problems can happen anywhere with quality control, we made mistakes too, sometimes they were caught before going out the door , other times it didn’t and we heard about it later.
 
STELLANTIS has had huge problems judging from this Jeep Cherokee site! Sad because we could never afford a Jeep until like 1999 when we bought our first Jeep and it was used . It was a GEM ! We drove it , fixed it for many many miles before it's body started to give way and it had way too many miles on it , It was a DREAM , but this 2015 Jeep Latitude well it has electrical problems that affect the power steering that NO ONE INCLUDING THE LOCAL DEAL HAS BEEN ABLE TO IDENTIFY , so like you all on this particular thread we too are frustrated and what to know what the hell happened to Jeep is it when Stellantis took over ? Management for Stellantis doesn't respond , so I wrote a letter to the head of the Dept of Transportation cause what is the point of keeping the business alive if it doesn't care about the product they already have on the roadway ? I hope we all can get resolution cause every thing we have is tied up in this 2015 Jeep Latitude and most American's aren't made of money !
 
2018 Jeep Cherokee No Recall on my VIN, but PTU has failed with identical symptoms. All wheel drive gone, rear wheels only - front end shimmy in all turns, feels very dangerous. What can I do? I have the identical problem as this 2025 recall but my VIN is not included?
My suggestion might not be immediately helpful, but I have an electrical problem with a 2015 Latitude and I reached the same point . I have now wrote the Dept of Transportation . If they don't hear from us they will never have a chance to possibility to help us at the very least all our letters will give them leverage to possibly get/force Jeep to do something to help us instead of us being the invisible long suffering .
