Z96 recall

[grimmjeeper]

If you have knowledge of such a thing, can you state when those began being used on the assembly line? Mine came off the line at the end of June, 2022 and has been recalled, 01A.

I don't know any of this for sure. And I don't know when they would have started using them.

If that where the case, why recall vehicles with that pump?

I don't know when those actually started going into production vehicles. Just because they spec a new part doesn't mean it goes on the assembly line right away.

The shop guy contacted me and asked if I wanted to get parts ordered so I said sure order em up. Said a month at least. Guess after 1st of year.

So whatever the new pump is fine, considering my original pump never died and all I did was add a little additive that was fairly cheap and I will continue to do even after new pump.

The pump has been modified from the old design. It's a new generation of the same family of pumps so it's a bolt in replacement. The internal parts have been upgraded to handle the low sulfur diesel mandated in the US now.

I haven't seen any news releases that support your claims. Where exactly are you getting this information or are you just assuming this?

The issue with the CP4.2 isn't that it can't handle low sulfur diesel, it's that the internal lifter in a vacuum can move around. Unless they have switched out that part for something that can't move around in a vacuum situation, they have changed nothing. You can spray a new coating on anything, and say you upgraded it, until you change out the part that's failing, they haven't fixed anything.

I can't find any detailed information whatsoever as to what is the difference between this "upgraded CP4.2" in the one currently in my EcoDiesel.

@grimmjeeper if you know specifically what has been upgraded, I'm sure we'd all love to hear it, along with your sources. Otherwise you're just saying it's upgraded without knowing what you're actually talking about.

My 2023 came off the assembly line in Nov 2022 and I have a recall notice. Just for reference.

Honestly I'm kind of hoping one of these YouTubers does this. There's a guy I found a while ago on YouTube who repairs fuel pumps in his shop and did a tear down on what exactly was wrong with the CP4.2.

I'm kind of hoping someone does a tear down of these two in the future.

Honestly I just find it interesting (to say the least) that a company like Bosch who would benefit greatly with a press release talking about how they've perfected their CP4.2, hasn't had any such press releases. If you go to Bosch's website, there's literally zero information about an upgraded CP4.2.

I mean, if that isn't a red flag, I don't know what it is!!

Kind of makes me think that maybe Bosch said you're on your own, and FCA decided to take it into their own hands to provide a "fix".

Honestly on the chances that this product is the exact same as the one currently in our Wranglers, you're only hurting yourself by getting the recall fixed. If you don't get the recall fixed, and your high pressure fuel pump goes to shit and grenades, you're protected. If you get it fixed with the supposed upgraded CP4.2, and it still fails later, good luck getting FCA to admit they f***ed up.


Me personally, I've decided earlier today that I'm going to stick with my high pressure fuel pump for the next few years, as long as it doesn't grenade, and maybe in 2027 2028 I'm going to have that CPX installed. It's an upgraded CP4.2, were they actually fixed the roller lifter.

I provided a link above to it but for those of you just reading this now, here's another copy of that link.

Right youtube I didn't think of that someone will do it for clicks!

If it is not a new improved pump seems like a dangerous thing for them but then Pinto's caught on fire and Chevy ignition quit working on the freeway and Toyotas just accelerated on their own. Probably a dozen other examples of car companies ignoring issues or covering it up.

Oh and the flechette Air Bags.

Oh and that is why I upgraded from a pinto to a chevette the chevette was safer. Just throwing that out there.

OK so by that accounting, it IS a different P/N than what most of these were built with.
that doesn't sound like what you said initially. thanks for the attempt at clarification.

Part number for the Injection pump is still unchanged and has been its current supercedence since 2/14/22. Part number is different in the recall, because its a recall part, this is normal for many recalls. As far as details its unchanged, if you get to look at the 2 person, you can see theres no difference in anything including part number stamping etc. Everyone wanted to argue “just because you dont see it dosent mean it didnt change” in me showing the clutchs for the 19A recall as well. So you can decide which pool you want to fall in with that. But as of right now, if you have the recall performed, then need to replace the pump due any failure after, the part you would order is the same part that was available before the recall.

Part numbers to be ordered for recalls are almost always different than a part that wouod be ordered after the fact. The part number in the recall is not a superceded number, its a completely different number, thats only able to be ordered under the recall and unable to be ordered outside of the recall.

My dealer service manager mentioned the other day that I have been on the list for the replacement since February. Not sure if that matters or not in the cycle of when a part will be available. He would not admit if they have replaced any at their dealership yet but I suspect certain individuals get the replacement before others. Would not even give me an idea of when the part might come in for me. I've been adding EDT every fill-up and continue to do so but really would like to get this replacement out of the way.
Do we have updates on how available replacements are at this point?

rigjt, and as you said:
“Part number for the Injection pump is still unchanged and has been its current supercedence since 2/14/22”.

so, it changed 14Feb22.

that’s after a lot of these things were built, and possibly why the recall is limited to the builds that it is.

FWIW, a quick search shows the new number listed in the recall available for order at multiple sites.
