Ok so I just purchased a 2014 ecodiesel overland 4x4. From everything I can tell the machine was kept in immaculate condition. Drove from Dallas to Houston in it today after picking it up and loved it. Absolutely loved it.

I'm seeing the issues about DEF fluid. My question is if issues are common if I take it to a dealership for oil changes/DEF refills? What else should I know? I watched tons of reviews on Youtube but hadn't really heard much about DEF issues until I found this forum. I kind of figured that at this point it would have had all the kinks worked out.

I've also seen the GDE tuner and was wondering if using one of those would keep these issues from happening?

Thanks!

Jeep redesigned the Catalytic converter. They've been replacing them as issues arrive. Usually it's a 2 step process. The first time there is a Check Engine Light for the CAT issue they try a software upgrade. Usually, a week after that the CEL comes back on, so they do the CAT swap. If you see any CELs or DEF warnings, bring it to your dealer. They do it for free, even if its out of warranty (though I think the warranty for exhaust issues is 100K miles). I've been filling mine with Blu Def from any auto store. As for oil changes, I've been doing them at the dealer.

I have the GDE tuner on my 06 Liberty CRD. I swear by it. But not sure what the tuner does on the GC. So far I'm very happy with the performance and fuel mileage so I haven't gone the GDE route. Yet.

I would recommend you refilling the DEF yourself. You can go to Wal Mart to buy it and be much cheaper than you having the dealership to do it.

The GDE Hot tune is best upgrade - I love it.
My reasons for going with GDE were mainly reliability and economy, but then I found myself having fun with the extra power.
@ 60MPH it averages 36MPG, @75MPH 31MPG and in the city 27MPG
On trip from Beaumont to Dallas and back 33.5MPG
Worst MPG I ever got was 25, and only because aggressive city driving (having full throttle fun :)
Best MPG I got was behind 18wheeler on closest adaptive cruise setting and speed around 66MPH. It averaged 49MPG on 5 mile stretch!

Those numbers are amazing. I need to go out and get that tune. I had replaced my stock cold air filter with the K&N 33-3029 air filter and wasn't to pleased afterwards. I noticed a drop in my MPG on highway. Grant it I have a 4x4 but 1mpg makes a difference while driving a great distance

Thanks for the info. I'm interested in this tune also. Is it a handheld flash? Are you 4x2 or 4x4?

Unfortunately they have to program your ECU in house. I got them to ship me pre-programmed and then returned mine, so no downtime. I'm 4x2.
There supposedly is someone who working on the handheld, but no luck.

If anyone is interested I was browsing on Amazon and saw that K&N has CAI #63-1570 for the Grand Cherokee Ecodiesel now. Hopefully Volant make one soon. I've had a good experience with their CAI when I had my Ram 1500 Longhorn
