DEF is something you should be familiar with if you bought a diesel. You can Go to pep boys buy 2.5 gallons for $12 and put it in the small DEF filler neck next to your diesel gas filler neck, NOT in your gas filler neck. The dealer can do this very easily too. In the same menu as your battery voltage gauge is your diesel exhaust fluid gsige so you van keep an eye on it. It van take a couple days for the gauge to register full after you fill it. Also its possible the DEF warning just came on due to the other batt/charging issues. Tell the dealer to check your def gauge to be sure.

all the rest seems to be related to your battery or charging system amd should be under warranty. You didnt happen to use a traditional battery charger on your car for any reason did you? I believe the new GCs use AGM batteries that use a newer type of battery charger.

Well if you know def is full then perhaps you could have assumed the evic message about it was triggered by your battery trouble. Does 700 miles on it mean there was no chance you had to charge the battery from leaving headlights on or any number of other reasons??.

you are the one asking for help and you are the one that mentioned the def evic message without telling us you knew it was full. And saying it has 700 miles certainly doesnt rule out anything.

Think you are taking me the wrong way. Haha. I expected better then this from Jeep,, not you. Sorry if you took it that way. I am just baffled of what the problem could be. Sitting at a dealer now waiting for them to try to figure it out. I've read in the cummins forums of similar def issues but the battery saver mode and voltage issues are weird to me. When I turn the heat on the voltage jumps to 14 from 10. When heat off, it drops. So odd.

sounds like it could be a bad grounding (earth wire) to me - good luck - hopefully the dealer can get it sorted for you.

It can happen with any car, new does not mean you are safe from breakdowns. Nor are other brands proof against it, my wife had a BMW that died on the trip home from new car delivery. It does sound like a charging issue which should be an easy and non invasive fix. Its frustrating but you have no option other than fix it and move on so you may as well get past the venting and put on your happy face.

Voltage dropping and rising with load changes sounds to me like a bad battery.

It happens.

That's why new vehicles have warranties.

If you have battery issues it can, and will, manifest itself through any number of random trouble codes since all sensors and computers run on...wait for it...that battery that's having problems. If the system voltage drops, sensors and computers get confused.

Keep us posted on what the problem is, as well as the fix.

Good to hear. Your issue reminds me of my statistics class where we learned about the bathtub curve and fail rate of a complex item..and a JGC qualifies as such.
Basically any failure should happen early in its life cycle from a defect or misassembly which is why manufacturers have a relative short bumper to bumper warranty. After that period failure should occur once it reaches its end of life...or at least that is what we hope will happen.

So, you should look forward to a long, reliable vehicle going forward.

Hello. I have owned my 14 Eco summit for 2 mths
That "service Def" just came up on my jeep. I have 8600 miles on already. I drive a lot. :) great suv... However. The dealership is telling me that the Eco def sensors are going bad and it will be in the shop for over a week waiting for new sensor. Thoughts? Anyone else have problem. Again. Very happy with suv. 23-26 mpg in city. 28-31 hwy. smooth ride and great technology. Is this def sensor a big deal?

Not quite, but at about 450 miles yesterday, I got the "shutoff in 200 miles" DEF error. Dealer called me today and said it was a bad DEF system injector. Will have loaner for a few days while they get the part.
