Diesel Died

[CrazyCooter]

Please let me know what additive you use , I have a 22 Gladiator with a 3.0. I live where it gets in the single digits. I also had the manufacturer add the block heater. I received my recall letter first week of June. I can't get parts for this thing. It ate a axle speed sensor. FCA Can't supply either the speed sensor or the high pressure fuel pump (HPFP). I WANT MY MONEY BACK. This is ridiculous. Got mid 60s cash into this thing. Wish I wouldn't have paid cash!

You would rather be paying interest on the truck you are unhappy with?

All joking aside, it's a sad state of affairs, but the failure rate is super low. I'm taking the chance in a 4K mile round trip vacation next week hoping we wont be returning in a rental Ryder truck towing my RV? See if Chrysler files bankrupt again in this economy correction like last time and screw their suppliers again? That will just make it worse.

If you live where it gets that cold I would run something like Optilube XPD All-In-One

I’m leaving next week for. 3k mile trip myself. Let the diesels roll.

In the past year. I got one trip from south of Pittsburgh to Denver. And two trips to Arkansas. 27,000 miles in 16 months.

I have a '22 Rubicon Diesel with 22k miles. It taken me through 8 states and a week long solo trip through Canada and first time ever having an issue with it.

I was leaving the store on Saturday and when i went to go from a stop sign, it went and about 100 feet after it started to make a rattling noise. Thought maybe it was my transmission, so popped it in N and then P and back to D and it started to rattle/studder and then died. Once it stopped on the side of the road i tried to start it back up and it was turning over but wasn't starting. Thought may be the battery was dying and hooked up my jumper box to it, but it had enough power to still crank over but never actually start. Then i guess i tried to start it one too many with fails and the system warning stated that it went into starter protection mode. Once i got my brother to give me a tow to the parking lot and out of the road, we checked the fuel and there was no water in it. It was pouring rain here in CA on saturday so maybe thought it had to do something with that but all my electronics were fine and no CEL or other lights were on. Also pulled the gas line to the engine and cranked it over and gas was squirted out, so it seems like it was getting gas or at least the system was priming itself. But still nothing. While waiting for the tow truck, i got some def as it was about 1/4 full and got the warning to fill up or it won't start in 310 miles, figured i would at least remove that possibility out of the equation, but still no luck. The engine would turn over but not start.

Tow truck driver tried to start it when they got there about an hour after the whole deal started, and nothing. Same thing, it would crank over fine but not start. He said sounded like the fuel pump. I got it to the dealer and of course they were closing early since it was NYE. Dropped it off and they called yesterday morning saying that they probably won't be able to look at it for at least a couple of days..... yay.

I know that there is the CP4 pump recall, but my jeep isn't listed on the recall. I picked it up on April 27, 2022 and it sounds like i am a victim of the CP4 failure.

Mine was built in March 22. Mine is on the list and I received my notice in the mail. Anyone know when the cutoff was for the fuel pumps?

CP4 pump failing is silent, the motor simply stops... pushing the start button the engine will just keep rotating and rotating..... there is no shudder, no bangs, no noise at all when it fails, it just fails

I don't think that's always true. Take a listen to this:

Umm that's exactly what I said happens.....
That noise is the starter AFTER the failure and of course those make noise

When mine went out, i was driving and it started to studder and bucking trying to keep going, and that is why i thought maybe it was something driveline related.

Really strange, 100% of every other one I've read about to include mine just let go and the engine stops because it's got no fuel going to it...

After i figured it out it was the pump, the studdering kind of made sense it was like when an engine gets starved of fuel.
