Recall: 3.0L EcoDiesel engine high pressure fuel pump (HPFP) failure (2021-2023 Gladiator)

[22EcoDs]

CSSMZ461AA - recall part number
68631088AA - warranty replacement part number

According to the tech, both are identical parts.

Exactly my concern. This is BS if true...

LOL I’m just messing.

Dude, we’re both in Vegas. What shop has your truck? My preferred dealer sent me a text today about scheduling for the Z96 recall, not sure if that is them reaching out to get me in the door or them reaching out to get it done.

mine is at Jeep Only

The dealer tech said the new pumps are made from 'hardened parts'. Otherwise, he doesn't have any other information. There are no software updates, though. It's simply a bolt-on part.

My dealer in Cheyenne said on Friday "we can begin ordering parts. We (every dealer) get to order one fuel pump every 14 days for now and schedule service as we receive them. Recall specifies a more durable replacement pump and a software upgrade. It will NOT be a CP3 as in 19-20 Cummins recalls, as it would never fit in the Ecodiesel. We do not have a Stellantis part number for the replacement pump, only a recall part number with no additional information or description." I am signed up and on a waiting list. I only hope it is an improved design with pinned rollers, hardened parts, better tolerances and clearances but I can not find out. Dont' know what to do if it is the same pump, different day. I will probably refuse the recall service for now in that case.

With that said, I don't fault anyone for selling/trading their vehicle if they are truly worried. Peace of mind, in my opinion, is much more important than worrying. But I also don't want to be the guy who is using fearmongering tactics to discourage those who don't have a good understanding of the CP4 and its track record. I've had my 2015 and 2020 EcoDiesel since new. I've had no issues. I have a buddy that just turned 450,000 miles on his 2015 EcoDiesel. He's still running the factory CP4 pump. We both run biodiesel and a fuel additive in every tank.

I agree. I was going to say earlier that I think most of these issues can be fixed with an additive. I have a 23 Cummins ram that I use archoil with, and no issue with the CP3 anyway, but I had a power stroke F250 prior and it had similar pump issues but I used archoil (hot shot prior) with it and never gave me an issue while most others had problems and warranty replacements.

The problem isn’t the pump per se, it’s the shitty diesel EPA/CARB rules with the ultra lower sulfur requirement, removed a lot of the lubricant quality of the diesel fuel. Overtime this is what implodes the fuel pumps. Also our CETANE ratings are lower than Europe. So the additives basically make up the difference and improve both qualities. The issue is not this diesel or the pump, the VM Motori diesel is widely used, it’s the lack of adaption of the pump to the US market, because of stupid government regulation.

Dealer notified me this AM they have allocated a fuel pump for my truck. Not sure of the timeline yet but still good news.

On another thread I posted that I reserved a new 2023 Jeep Gladiator High Altitude Diesel at a dealership. Was told today that they have the replacement fuel pump but are wating on another part, which will arrive 10/18. The install will happen after the 18th.

Stellantis issues recall of over 175,000 Dodge, Jeep vehicles due to engine issues (msn.com)

Stellantis issues recall of over 175,000 Dodge, Jeep vehicles due to engine issues

April 19, 2023

Stellantis is recalling numerous Dodge and Jeep models due to issues that could prompt a sudden stall.

The largest of the recalls, impacting a total of 131,700 2021 Ram 1500 vehicles, was cited as a software problem that could cause engine stalls. The recall notice posted on the NHTSA website explains that “powertrain control module software may cause an incorrect fuel mixture condition in the engine, and result in an engine stall.”

In a similar issue, about 45,711 vehicles equipped with the same 3.0L diesel engine could stall due to the potential failure of a high pressure fuel pump (HPFP). The recall notice impacts 2021-2023 Jeep Wrangler and Gladiator models, as well as 2022-2023 Ram 1500 vehicles equipped with the aforementioned engine.

The automaker has instructed Ram owners affected by the software malfunction to update the Powertrain Control Module calibration software at dealers, which will be done free of charge. Dealers will also replace the HPFP and any additional fuel system components in need of service sans cost, according to the NHTSA notice.

Notification letters for each of the recalls should arrive to affected customers by the start of June.

So today I’m driving along the highway in my ‘21 JTRD at 59 mph in Wasilla, Alaska, having just topped off my 1/4 full tank of diesel with a full fill up. 48,058 miles on the odometer, perfect running engine up till today, and suddenly the eco-diesel sputtered, like it was choking out, then I received a “Service Electronic Throttle Control” fault on the dash screen and the “Auto Start/Stop Battery Low” fault message as the vehicle went immediately into a limp mode that I knew was really a ‘pull over or stall on the highway’ type situation. I quickly found a turnoff from the highway and coasted to a stop. The engine shut down. This all happened without ANY prior indications of something wrong. Zero warning.
I tried cranking it two or three times, would not start.

Local Wasilla Jeep dealer said it would be several weeks to be seen. Unsatisfactory. Had tow truck deliver to Alaska Diesel Repair as my next best option. These guys seem like they know their diesels! Thinking it could be water in the fuel system or something worse like the high-pressure fuel pump.

Once the diesel shop has a chance to look at it, if it seems to be the latter fuel pump issue or other warranty-related issue, I will have to have it towed to the Jeep dealer. The recall for the high-pressure fuel pump has not been done on this Jeep yet, and I was planning to schedule it once I learned parts are finally available. Like many, I’ve also been on this recall for so long without any parts available that it seemed like it was not a priority for Stellantis.

If anyone is interested in the outcome, let me know and I’ll post updates as soon as I receive any information.

Have there been any report of the recalled pump gone bad?

When I had mine done it was that you had to be placed in the dealerships list. They make an assessment as to which type of repair is needed. One was just the pump. The second is much more intrusive requiring the pump, fuel lines, injectors…etc. Each dealership has to place you on a list as they can’t stock the parts. I’m sure Alaska is a totally different situation due to its remote location, but once they put me on a list, my dealership in a small town in Florida could only have one outstanding order and the rest stay on their list.. as soon as they would receive the parts for one repair the next one in Line2 would get their parts ordered because each dealership had an allotment. When Mine had the pre-inspection I was 12th in line and it took 12 weeks since that dealership had allotment of no more than one per week.

Yup that's what my dealership did. I would call every month or so to make sure I'm still on "the list" untill my appointment was scheduled

I just had mine grenade this last weekend. I bought mine in Jan 24 it’s a 2023 model. I was at the dealership today when they pulled the filter and it was all glitter. I’m not sure if the recall was completed prior to my purchase. Anyone know how labor intensive the repair is going to be? Looks like they have to clean the entire system out.

 

[aFatBird]

All 3 dealerships I've contacted still haven't reached back out to me saying they got a pump for me. When I do check they still say it's backordered. Casually waiting for over a year for this recall now.

Your 2023 year model truck would have had a stop sale due to the HPFP safety recall, preventing it from being sold until after the recall was performed. For a glimpse at what all is involved in doing the repair, you can consult the instructions in the HPFP recall (search for recall 01A / NHTSA 23V-263) where it details what's needed for a "contaminated" vehicle.

Update 3/24/25: So today was the first day my Jeep was diagnosed. Long story, but it involved a lot of waiting to get service and 3 separate tows to 3 different locations. My '21 JTRD high pressure fuel pump shelled out as expected. Dealer says they already ordered parts and should have it fixed within 10 days. When I asked about the performance record for similar repairs, the Service Manager stated that in the past 18 months of replacing the fuel system components and pump on other diesel Jeeps they haven't had any repeat or recurring issues FWIW. All covered under warranty (Just over 48K miles on my vehicle).

I really hope this is a one and done event as I've otherwise been really happy with my diesel powered Jeep. Sharing in case anyone else has a similar experience.
