HPFP Replacement Recall - Post Fix Review

[Jteakus]

@Rusty PW
Do you know what has been upgraded in the new pumps to make them more durable? My fear is they are just replacing them with the same pump just to get us all out of warranty period.

Not likely that they didn’t change anything, doubtful the NHTSA would sign off on that and also unlikely Stellantis would tell the NHTSA they made improvements to remediate the issue and then ship the same old thing. Why would they open themselves up to that kind of legal liability by misleading the NHTSA? Not to say I blindly trust their solution, the changes may be a bandaid/bare minimum fix that only kicks the can down the road, but IMO it is a near certainty that some elements of the pump were changed.

The details will come out sooner or later, either via independent tear down or from the manufacturer, Bosch or Stellantis. No sense worrying about it in the meantime.

I see your point. However, I don't see why there is little to no information about the "upgrade" available. All I have read is "hardened parts" which is a rumor at best and will not cure the problem with the CP4.

I read hardened parts and something about the rollers on the bottom of the pistons.

Got mine done pump only I drove it in . Had a leak and its been fine since and I can tell any difference . Elsinore Jeep has em in stock for same day ( at least with mIne )

If they pinned the roller on the pump should be good then

One was able to keep it (I think Rusty).

I had the advisor bring it to me and I pulled control valve on top, some small flakes were present on mine.

But the advisor told me they needed it and I couldn’t keep it.

along with the pump a few lines get replaced…

make sure those lines are replaced.

Is that easy to find? I have ZERO confidence that my dealer is going to do this right since the dude argued with me on the phone that the recall doesn't call for a pump replacement unless there's metal in it. Took me having to show the guy the paperwork and argue for awhile about it. Sure doesn't give me that warm and fuzzy that it will be done right.

You had metal flakes ? I thought that made it a cab off job?

why would it be a cab off job? if they find contamination in the lines, they just replace the injectors and fuel rail in addition to the pump, which is all accessible from the engine bay.

I thought they had to replace the lines coming from the tank and lift pump as well, since the system returns fuel back to the tank.

When my first pump went out, they replaced everything that was after the pump and the fuel line connected to the pump. The recall instructions also don't mention replacing any return lines to the tank just everything after the pump.

Just got mine back yesterday, it was in for a rear locker sensor replacement but also had them do the pump recall while they had it. They did just the pump for the recall, couldn't talk them into letting me have my old pump citing liability issues (I call BS, but it wasn't worth fighting over), and there are no leaks or problems. I haven't noticed any difference in how the Jeep drives or sounds, though in all fairness I haven't driven it much since yesterday and I don't hear all that well anymore.

One other note, according to the paperwork they also did a PCM software flash as part of the recall which makes me wonder if there's a newer version or a revision to the recall instructions. Anybody out there have some insight on this?

The PCM flash would be new and that's not part of the paperwork I see. That would greatly effect my ability to get mine done...

Mine was done on the 3rd. There was no flash with mine.

@DylanM Can you check if there is a part number for the PCM flash on your paperwork? Something like 68353396AH.
