Diesel Engine issue tracking thread... also please post if NO issues!

-600 miles CEL, both nox sensors replaced and bad connector fixed
-1300 miles, smog test failing as “not ready”

Am starting to feel a little bad about this motor

Same for me on the emissions stuff. I did learn that a diesel will pass smog in CA with any 2 monitors not live. Wasn't able to get them all to trigger and it still passed.

9k miles, def pump failure and cracked exhaust manifold. Can had to be removed for replacement of the manifold. Multiple derates while pulling my camper. All that said I still love it!

Almost 7k miles with zero issues at all

11,000 miles. The chrome on my door handle is peeling. Thinking about a class action lawsuit.

18,000 miles and no problems

39K in 14 months. Zero issues. No additives. All oil and fuel filter changes and other service (including recall) by dealer under Jeep Cares. Liked their work and happy attitude so much I bought their package for another 3 oil changes for $225, which is way cheaper than doing it myself.

No problems at 23,000 miles

2021 around 17k miles - mine jerks / stutters

Dealership says it has no codes … drives normal but up an incline or under a small amount of load it will jerk pretty bad at around 50mph or on the interstate holding 75mph or if I give it throttle to pass.

I am at a loss of ideas for what it is. Doesn’t do it all the time. It’s def not right.

On the second day, I had the P00AF code, Dealer fixed it (haha), a month later the same code, a month after that same code plus 2 others.
Then at about 6mo. it stranded me towing a small trailer. We were about 2 hrs north of Vegas on the 95 freeway. The message I got was Service exhaust system see dealer. It would only go 40mph!
What happened was the system didn't do the regen. The dealer could not tell me why and FCA could not tell me why. In its first 6mo, my little red truck spent over a month in the shop. That was 9 months ago and it has been solid ever since.

P00AF code

What are the symptoms to that code?

They pulled the cab to replace exhaust manifold? i have a strange noise on the left side i can hear at lower speeds, sounds almost like a belt or idler, but could be exhaust. What kind if noise did you get

 

[Wattsimages]

What are the symptoms to that code?

It really had no preliminary symptoms. I was on the highway and the service engine light came on and then it went into limp mode. If you shut the truck off/on it will run fine, sometimes for days.
The code has to do with the boost controller and there was an FCA bulletin.

Had CEL with 230 miles the MAF sensor reading was off. Deleted it and it didn't come back till 2k miles, deleted it 2 days ago and it's back again. I would ask Jeep to give me one and I will replace it but I know they'd prolly void my warranty. I would almost rather buy a new MAF and do it myself than have the dealer touch my truck. Considering the Banks digital thingy to be able to monitor and run/delete codes... 22' JTRD aside from this I love this thing the torque and tranny are sweet...
