My 2014 JGC CRD has 11,108 miles on it. I bought it new 10 months ago.

The MIL came on again today, exactly 80 miles and 2 days after picking it up from a 2-day service where they replaced the catalytic converter to address another P20EE code. This is the fourth time. All three previous times that the MIL came on were for P20EE codes.

(MIL = CEL = check engine light = malfunction indicator light)

This one, it's likely P20EE again. I called the dealership right away and made a service appointment for Monday.

Great.

There's 2 sensors and an injector that have to be removed/reinstalled. possibly something got missed. CAT replacement & new software seems to fix it for most right away.

So you have the new cat and still got a code?? Man I was hoping that was THE fix for this issue. Let us know if it ends up being an unrelated code please. My wifes is at 5k and 7 mos old and perfect so far, but I am expecting every single one to need the fix. Is everyone else with good luck so far thinking it is inevitable to need the new cat?

Just got this code again for the 3rd time. 1st time it went off of its own accord. 2nd time it was reset at dealers who said it was fixed by the update. Well just as was experienced by my son the light came on after a few hundred miles. He had a lot of parts replaced and as I write this his vehicle is still in being serviced. I will bring mine in again but have no expectation that they have a clue as to how to fix it. Oh my son had injectors, pumps and catalytic changed. One note is that my son contacted the lemon law group and it seems that they are very interested in pursuing this problem.

I dropped her off yesterday morning and they've had her for two days. Today they called to say they have to contact Chrysler (with some kind of 'star call', or something like that, I didn't quite get the words he used). The code was P20EE again, and they've already done everything they're supposed to for this code, so basically they are stumped.

They said they'll need the car through at least Thursday.

Thankfully they gave me an Enterprise car rental, and at least it's a 2015 JGC Laredo with the V6 gas engine. This is actually the third Enterprise rental they've given me due to P20EE since June, the second time was last week (Dodge Ram 1500 with the 5.7 V-8 Hemi that time - BIG truck. Thirsty too.).

Maybe it's just me, but I don't think it's a good sign when the dealership's shuttle driver and service personnel recognize me by face. The guys at Enterprise do too.

What is the TSB number. Just got the code for the 2nd time (2014 with 10,300 miles). I want to walk into the dealer this time with the TSB in hand :slapfight:and don't want any excuses (they have been good so far). 1st time they did an update. What am I in for next? :(

I know what the P20EE code is but what does it actually mean? Since it doesn't seem effect the drive ability, and it appears that the new cat, pump and injector replacement is not working, is it possible that the last and only fix would be to just wipe the code from the computer as if it never existed? Is there some law on the books that says every diesel sold in the US has to monitor the SCR in this fashion?

Hmm, that seems like a long time driving with that code tripped. :eek:



I got my JGC back today, finally. It took a while to find what was wrong. It turned out to be the connector for the cat converter had a bad pin, so didn't establish a complete connection.


Welcome to the Enterprise Club
Yeah, really. This time I got a 2015 JGC with the gas V-6, so at least I had the same rig as mine.

I still have it, though! When I went to pick up my JGC today, the gas flap's alignment was so noticeably off that I mentioned it to them, and they said they'll fix it.

I got more gear out of my rig and transferred it to the rental. Dog crate, stuff like that. We're moving in to that rental JGC, it has been six days already. The dealer is paying for the rental, except for a $5 per day upgrade to the JGC (otherwise it would've been a Chrysler 200). $5, it's practically free.

The Enterprise Club, it'll be for a while longer! All told my rig has been at the dealer's for 11 days and counting since I bought it.

At least, fortunately, the dealer is taking good responsibility for fixing the problems!

Hopefully P20EE is finally fixed! Won't know for a few days, though.

I've had a code off and on for the last 2 weeks now - which won't allow me to do remote starts in the morning :(

Bring it to the dealer on Friday to see what it is (don't have a scanner so can't check easily and don't want to run to a store to figure out what's wrong). Since CV joint is grinding and there's another recall and whatever else reprogramming they need to do the dealer is hooking me up with a rental. Will update when I find out.

^^^ Good luck!


Just got the code again today. I'm going to have to call to take it in. Just not in the mood to fight with them doing everything other than replacing the cat. So I'll talk to my regular service rep and see what they say.

It's after 1am here and my wife and I just got home from a 350 mile test drive of our rig. I rode her hard, I rode her soft, (the rig not the wife), we did some 4-wheeling, and I did some aggressive and fast driving. We crawled over steep dirt hills (J-1 / Panoche Road between Hollister and Firebaugh; also Griswold Hills and Tumey Hills, for those who know the area).

No MIL. No sign of the MIL. So far so good!

Gotta say, though, that I LOVE LOVE LOVE that CRD engine! While my rig was in the shop I had a loaner, a 2015 JGC with the 3.6L and for 700 miles I drove it, it got only 16 MPG overall.

Around town the CRD is much much peppier than the 3.6L. On the freeway, passing speeds are pretty good although the 3.6L is also decent, but the 3.6L is louder while the CRD sounds more refined. The 3.6L's exhaust note sounds more "growly" while the CRD again is more refined.

Then there's the fuel economy and I know we all know about that, or most of us.

Measured fuel economy during this 350 mile test today:

► 28.6 MPG during stop&go, slow&go freeway commute rush hour, then when things opened up I cruised at 80 MPH (70 - 90 MPH) with a light, gentle foot for a total of 122 miles

► 22.8 MPG on the freeway cruising at 80-90 MPH (hey, it's California and I-5 where the limit is 70) with a heavy foot meaning harsh accelerations, stomping the pedal to pass, for a total of 169 miles

► 24.1 MPG overall for the entire 350 mile test today, including a little 4-low action and Off Road 2 height on the Quadra-Lift (some, not a lot)

For those who know the area I crawled up and down the steep switchback bypass a few times shown in Google Maps here: https://goo.gl/maps/fDK0v. That's definitely 4-low, high clearance action.

Like I said, so far so good!

The dealership did a software update on mine in December to fix the code. Now they are replacing the cat and a gasket after it coded again. I hope they figure out the solution. This diesel bounds up hills that I crawled up with my 2011 3.6 when towing my travel trailer and better MPG!

I'm hoping they'll figure it out for you. Agree, this is a great rig. So far for me it has been 1,000 trouble free miles (P20EE) since the fix at the end of January.

Please do keep us updated.

Mine is in the shop as I type waiting for the part.

How long did you wait for the part - as I assume it, too, was back ordered.

Mine is in the shop as I type having the Cat replaced. Hopefully this will do it. I bet I've cleared the code 25 times while waiting the 6 weeks for the part to come in. They're also checking my "service tire pressure monitor system" message that I have gotten twice. And here's a weird one, the pass. side DRL and orange side marker lights did not light 3 times when remote started. I bet I'll be back to the dealer for a TPMS module and a new headlight assembly or module. Ahh, the fun never ends. At least I have a Ram crew cab as a rental.

On further review, it looks like mine is a P20e9 and may just be def pressure related. On a positive note it was gone this morning so I am keeping my fingers crossed. Either way these exhaust systems are finicky as hell.

My build was November sometime, part of the initial backlog.

Noted in another thread that I was told the CAT was back ordered (as has everyone), and I ended up getting it in about a week. Not sure why...but my Service Manager told me that a Chrysler rep was looking at my car yesterday, called it in, and it was here this morning. I'll take it...
