It's a 2019 and still under full warranty for another 4 months. At the end, but it should still be covered.

I talked a with a different dealer, just for the fun of it, and they told me this definitely is a warranty issue. Not even a doubt.

So I gave my dealer a chance to make things right or they will loose a costumer.

In Norway you can choose what dealer to do both service and warranties at.

The car warranty is European, so you can choose your JEEP garage in any region or country.

Can batteries be considered consumable? like bulbs or tires or filters?

Look at your warranty book

For example Ford France guarantees the vehicle for 3 years but the 12V battery is guaranteed just for 2 years

Awesome! Wish my warranty was still valid for my planned euro roadtrip lol.

But yeah, no separate mentions of battery in the warranty book. So that should be covered.

just get rid of that stupid ESS battery... it is nothing but trouble..

I don't see any circumstance where the aux battery would be covered for 5 years. That is crazy.

Just fix it yourself, it takes about 20 minutes total. Replace both batteries.

Often times warranties that are standard (by law) in EU/EEA we (Americans) think are just a fantasy. I honestly wouldn't be surprised that the aux battery is warrantied for 5 years in Norway.

My Wrangler was manufactured in July 2018 and delivered in December. The 2 batteries are original, and when the ESS no longer works I will change the 2 sets. (less than 250 euros / Dollars) But today everything is OK... Quality of components for EU? maybe

I'm assuming the 2.2D's ESS wiring is similar to that of the 3.6L gasoline engine.

If this wrong someone will chime in.

That said, this video, which I looked over first, seems an accurate explanation of what to do. Ignore the "changing the battery" part.



I encourage you disable the Autostop system by pressing the button to turn it off each time you start up, or by acquiring aftermarket tech to do so (ask if you need links to products that do this or search this forum.) If you don't you' run vehicle appliances during an ESS event from the main battery and could--although unlikely--rob it of starting power. (Many other model/brand vehicles run ESS off one battery, but few vehicles are as likely to have aftermarket current drawing appliances like a Wrangler with (most JL models) its two batteries.)

As for voiding your warranty, this change can easily be reversed. It strikes me as insane to pay the fees you've been quoted to maintain a system you simply don't need and can easily restore should you need to put the vehicle back to factory wiring.

In other threads on this topic I got the impression that there was more to it than what was shown in this video.

Any links? I mean you're right, there's more to it in the sense that some JLs don't have auxiliary batteries and ESS wiring setups like those in the original 3.6L 2.0L JLs of 2018; and maybe the OPs overseas 2.2D is just such a JL. But that said, what other steps or conditions regarding the JL type being discussed might you be referring to?

I recently had my main battery die, and the cost to replace the AUX was roughly equivalent to the cost to buy an AutoStartStop to permanently disable ESS, so I just went that route.

Here's the full walkthrough of what I did, with pictures and links. Been running for a month without it with zero issues whatsoever.

Batteries are consider wear items, here in the US they will not warranty them for as long as the drive train.

The auxiliary battery is an Aux 14, The main battery should be changed at the same time. Replace the main with an H7 group 94R. You do not need to buy them from the dealer, as you will much more for an inferior battery.

You will find many threads on this site about how to change them out. I don't know how the laws are in Norway when it comes to eliminating the stop/start feature. If it is something that isn't checked for at vehicle inspections, then I suggest eliminating the stop/start function and take the auxiliary battery out the the charging loop. Essentially eliminating it's ability to function. The H7/94R will likely function well with the stop/start, even with the aux taken out of the loop. However, why keep the draw and complication of that system if it's not necessary?

So I have a problem where my ESS doesn't work, took the car into the dealer and they found that the battery was not taking charge.
The importer of Jeep to Norway, do not want to let this be replaced under warranty, which is found insane.

The dealership quoted me $750 for replacing just the ESS battery.. Likewhat? The price of the battery itself supposedly is $670.

What to do now? Can I get any battery? What are the specifications for this battery?
And oh, I have the 2.2D.

Thanks in advance for any replies.

Enjoyed the 30+ days I spent in Norway when I was in the Corps. Bardufoss most of the time with a trip to Tromso. Beautiful country!

if this warranty-thing doesn't sort itself out I'll definitely disconnect it.

Is it a brand new vehicle? If so then yea the warranty thing should cover it. If it is not a new vehicle then it is highly likely that consumables are not covered. If they were you could claim that running out of gas is a warranty issue as well. Changing oil is and so on.

On the other hand, if the battery tests okay, and is simply not being charged by the vehicle, then that is definitely a warranty issue.

I suspect a lot of the cost is related to labor. They have to pull the passenger side fender and liner out. And IIRC the fuse box has to be moved or something like that. I did it about a year ago on my 3.6 and it was not a fun job. Technically easy, but time consuming and I ended up having to go to the auto parts store to get replacement plastic rivets for the fender. It is almost guaranteed that they will break when you pull the fender. Both my batteries were dead, but I only paid about $400 something to replace both.
