TSB 09-012-22

[pacificoflyr]

I haven't seen much on here regarding this TSB 09-012-22. Has anyone had their dealer perform this? My truck sounds terrible with light acceleration or basically ANY load on it. It also has a rough idle that comes and goes and the dealer, "Verified customer complaint that the engine pings on acceleration. Removed PCV Hose and found oil in the hose indicating that there is oil being consumed and the PCV is not sealing properly."

The truck is a 2020 Rubicon, 6 speed, that went into the shop with 4,999 miles. What is very concerning to me is that my warranty is up month after next and with so little miles this crap is already happening, not including the unsolved clutch recall. I miss my TJ & LJ ?

I forgot to add:
"Recommend performing the TSB repairs by removing the cylinder heads cleaning the piston and combustion chamber and installing a revised PCV." Parts on back order of course...

The 3.6 likes higher revs. If this is a manual 6 speed it may simply be the way you drive.. no offense. Now the PCV valve sounds like it does need replaced. just my opinion take it for what you will.

I’m not a mechanic so I can’t offer any advise on your issue but I wanted to say that you can still buy a Mopar extended warranty through some dealers which are quite reasonable if you have any long term concerns.

No need to remove the heads unless you have a lot more than 5,000 miles on it - get the latest rev PCV installed.
With that low mileage, you don't have massive carbon built up. Run some upper cylinder cleaner through it, or replace the PCV and take it out and rev it up.
I can't imagine with extremely low miles like that (it must have sat most of its life! I put that many on in 6 months). The only other idea is that it only ever made short drives, never got really warmed up, short commutes less than 30 minutes or enough miles to totally warm it up and that's bad on engines. Short drives, never getting hot = carbon and troubles.

Too many people try to keep the RPM down on these and that's a bad thing.
Mine regularly sees 3,000 to even 5,000 RPM and the other day just about 6,000 RPM when trying to merge onto the poorly designed interstate system here.
The point -if you are trying to keep rev's down like old school engines - don't. Keep the RPM up.

Anyway, back to basics - you need to define the problem better with more particulars - at what RPM, what gear, and so on - if you are running at 1800 to 2,000 RPM and accelerating, downshift.
Otherwise, please try to fill in the blanks like the RPM range it rattles in, and so on.

I'd wonder how much oil they saw - there's going to be "some oil" but that's an objective thing as to how much is a lot or is ok So hard to tell what they were seeing.

Thanks all. Living on an island with a 7 mile commute once a week most likely doesn’t help. Higher revs and a new pcr it is.

Call the head office for Jeep to make sure they are following you on this issue. I have had to do the same thing for my 2023 Gladiator steering wander.

..............
What is very concerning to me is that my warranty is up month after next..............

First retail deliveries of the 2020 Gladiator did not happen until late April 2019. 2020 Gladiators if under mileage, should not be aging out of 5/60K Powertrain warranty until April 2024 at the earliest.

My Mojave is in the shop for this TSB but they are refusing to cover it. Instead they are trying to charge me for new spark plugs and a new PCV. I'm at 59,333 miles.

Where is @JeepCares on this? Does Jeep really care, I am thinking not. I haven't even been called back by my dealer to complete this TSB.

Have you set up a formal case via JeepCares?
They are short-staffed from what information I'm getting. It figures - if you look at employment problems today, people want to work 20 hours and get paid for 80 and every business I know is having trouble staffing. They are no exception.
Even my dealer's service manager is talking of short staffing at Jeep and keeping communications going with STAR.
He told me he had an open bay - down a tech - (and I don't know if it was joking or not when he said he should hire me........... I'd say no, anyway)
I had to wait 6 weeks to get in to look at a transmission leak. I've heard that story over and over - a month to 6 weeks just to get something looked at.

I guess maybe I just kept after them - politely, but I didn't let them forget me.

We're here, pacificoflyr; just had some time off for the Thanksgiving holiday. Thank you for your patience. If you are still in need of assistance, feel free to send us a private message.

So, Bill, are you saying that my 37's on the freeway, against the wind, is actually very good for my engine? Lotsa 3000rpm here. Glad i never recalibrated
