Take the battery you purchased back, the KL requires an AGM battery, the same size/capacity is not enough. Shame on them for selling it to you.

Since my post, I've replaced the Kirkland (Costco) battery with the OEM one that was in the Cherokee - the original battery was not giving me any problems, I just figured I'd change it out since (I'm guessing) it is the original battery that the 2015 KL was sold with. Now that I've replaced the battery back to OEM, I'm still getting no Start/Stop and still receiving the "Stop/Start not available Battery charging" message. Not sure what's going on here... The original OEM was out of the vehicle only 2 days ago.

I've attached pictures to this post of the OEM battery, and the Kirkland. It's funny how my being proactive has actually caused me some issues.

 

My start/stop quit working as soon as the battery was 2.5 yrs old with 55,000 miles on it but the battery was still working so i replaced the battery and the start/stop worked again. My 15 battery had a 2 yr warranty so it was getting due lol.

 

Mine did the same in 3 years. Installed new AGM battery and all back to normal.

 

Don't start and stops have 2 battery?

 

The smaller battery as i understand it is primarily for the ASS (short for the Aut0StopStart) system but could be wrong.

The charging system in these newer vehicles with AGM batteries is incompatible with conventional old school lead acid batteries.

What you might try is disconnecting both batteries for a while, reconnect and see what happens. Then give it some time.

Its also possible the small battery died but that would be a wierd improbable coincidence.

 

what amazes me is that you would even care about losing the stop/start as much as everyone(including me) hates this super annoying feature... here you find an easy way out of it and you go and fix it! lol

 

Yeah, I was hoping this thread might be a new way to disable and never have to push the button to turn off the extremely annoying start stop every time I start the Jeep. Absolutely worse design ever.

 

Once a battery is changed on a KL, it can take several days for the system to get back to ‘normal’. Give it some time before worrying too much.

Now where does the “two batteries for ESS” idea comes from? My 2019 KL only has one battery. That battery powers the ESS....and everything else. The Cherokee is not a Grand Cherokee nor is it a Pacifica....

Thanks, good to know.

 

Well, yesterday morning before starting my Cherokee, I wiggled the wires on the IBS and after the engine warmed up, the start/stop started working again! Now of course, there is more than one variable here - I re-installed the OEM battery 2 days ago, and I wiggle the wires leading to the IBS which is connected to the negative post connection of the battery. So, now I don't know which one - or both actions - might have triggered the ESS ti start working again.

I would still like to replace the battery. I'll make sure to purchased an AGM, and most likely get one from Canadian Tire. Though, I may just wait for a sale. Again, the OEM battery is only 3 years old - when would you change it?

Thanks for your help!

Well.. looks like I wrote my post too soon - I was out today, and the Battery Charging message was on again. ESS did not work all day. If I go out again today, I'll try wiggle the wires from the IBS again, if not I'll have to do it in the morning before going to work.

 

Yesterday, I replaced the OEM battery with a Motomaster AGM - they were on sale, and I had Canadian Money to spend!

See attached pics of the new battery. When I replaced it, I drove around for a bit and the ESS was not working. This morning driving to work, it's working again. Hopefully when I leave work today to head home the ESS will still be working.

You just replaced the other old school battery with an AGM?
I was under the impression right or wrong that you replaced the battery with an
AGM a while back and still had the issue.

Anyhow, good luck with your stop/start issue which i keep forgetting to disable every time i start up.

 

I looked at SmartStop but I have a 2018 Jeep Laredo and you can't just plug it in. Its a lot of work to install.

 

Yeah, I was hoping this thread might be a new way to disable and never have to push the button to turn off the extremely annoying start stop every time I start the Jeep. Absolutely worse design ever.

Why is it the “worst design ever”? Some vehicles do not have the option to turn it off, fortunately we do. Since this type of economy enhancer is appearing across the industry (Ford, GM, FCA, Honda, Hyundai, Mazda, Toyota, etc.) I’d say that Jeep’s take is one of the better ones.

sorta begs the question... save fuel at a few dozen stops..
but how much is the JEEP starter gonna cost ??

stealership or thieving gas station ?

EASTCOAST stealerships are asking $870 american dollars !!!!!!

oh.. o OH the $175 diagnostics will be nig be added to the $ 870

Because its not an option. You have to turn it off every time. I believe that was a requirement for Jeep to get the minuscule, if any, fuel improvement. If there was no ability to turn off the stop/start, I would not have purchased the Jeep. This is a Jeep, not a Toyota Prius.

Every motor vehicle already has a start/stop ignition switch. If I want to turn off the engine in traffic, I can with no help or force from a car manufacturer.

I live in Florida and when it turns off, the air conditioning is reduced. When I pull into the garage it turns off and starts back up when I place it in park. The Jeep turns off when I am waiting to make a left turn in traffic. Because there is no time delay, it immediately turns off when at a stop sign even though the stop is less than 2 seconds.

Its poorly designed, unnecessary and unwanted especially in a Jeep and as the customers that paid for the Jeep, we should have the ability to make the decision, not a paternalistic car manufacturer.

Don't blame Jeep. It's the Democrats you voted for forcing it on you.

 

It’s electronically possible to keep the stop start from engaging but very complicated and would invalidate any warrantee you have. Just need to remember to switch it off, like putting on your seatbelt. When it’s on, I get strange looks from drivers who wonder why I turn off and on my motor at every light!!

 

With start-stop on so many vehicles in the past five years I find it odd that very many people would give you “strange looks”. Perhaps instead of reacting to the start-stop they are reacting to you. Are you by chance somewhat strange looking?

Here is my experience with Sto/Start and the battery. https://jeepgarage.org/f216/stop-start-206117.html

Just my $.02 US worth.

 

My Cherokee is currently at the dealer for this same reason: Start/Stop Unavailable Battery Charging. I was going to change the battery, but I decided to try and see if my warranty will cover it first.

 

Any update from the dealer? Mine just started doing this.

 

Went to the dealer a couple of weeks ago for this and something else. They fixed my other problem and said "it's probably a battery issue" for this.
Been charging and starting fine but I'm still going to replace it soon.

 

I had that problem and error message on my 2018 JGC.
The dealer replaced the start/stop battery (yes there are 2 under the passenger seat) as well as some other modules.

 

Hi all:

So just to give another scenario here.

I was on vacation for about 17 days. Left the car parked in the lot.
When I got back everything worked fine, except the Start/Stop. I got the message "Auto Start/Stop Not available. Charging". Or something to that extent.

Drove it a for a few days and everything was fine.

My take:

The auto stop/start battery gets its charge from the main battery.

So the smaller battery had drained and just needed to be topped up when I got back.

And that takes a bit longer than just a couple of 5 mile trips every day.

Good summation. That is the issue with modern vehicles especially the Cherokee. There is always electrical activity going on even when the vehicle is off or as I should say "sleep" mode. One of the reasons an AGM battery is needed in these vehicles. You are correct to notice that a 5 mile trip is not near enough to recharge completely the battery. Run/Stop puts some serious demands on the battery. It simply will not work if the battery charge get too low or the battery is nearing "end of life" status.
I do not have run stop on my 2014 but I do replace my battery at 4 years maximum. I still have lots of electronics running on mine. I invested in an AGM battery on mine last December because of this.

 

There is apparently some confusion here. The OP (Original Poster) has a 2015 Cherokee KL. The Cherokee KL 2014 -2019 has only one battery, located in the engine compartment. The Grand Cherokee has two, if equipped with ESS. The Cherokee KL 3.2L V6 models 2015-2019 have all been equipped with ESS (Engine Start/Stop) and require an AGM (Absorbent Glass Mat) battery. Installing a non-AGM wet cell battery will result in very premature failure of that battery, as non-AGM batteries cannot handle the load that the ESS system places on them. Many auto parts stores' web site battery finders will incorrectly list a non-AGM battery as an appropriate option for the 3.2L V6, so be certain that you choose only an AGM battery if you are purchasing yourself, and don't allow an unknowledgeable parts counter salesperson to sell you the wrong one in error. After replacing the battery, it may take several days (depending on your driving distances) for the ESS system to become available again, once the IBS (Intelligent Battery Sensor) resets the system. Hope this helps.

 

I saw that initially and was confused since the Cherokee battery is in the engine compartment which normally would not need an AGM. The charging circuitry for an AGM is different than a Wet battery and there is a battery management system that controls the charging of an AGM battery because it is possible to overcharge them.

 

It should be noted that the Cherokee KL and the various Grand Cherokee model platforms do not share most features, systems or engine and drive train components, so care should be taken to be sure that you are addressing questions in the correct forum for your vehicle type and not potentially offering information that is not valid for the poster's vehicle or their concern.

 

I second flyfisherman. I have a 2019 KL with 2.0 L turbo. I read about the hurricane turbo when it came out in the 2018 Wrangler. That configuration had a feature called etorque. The etorque system runs the auto start/stop system with a 48 volt battery and a water cooled motor/generator unit (MGU) that auto starts AND delivers a low RPM torque boost to the engine via the serpentine belt. This system has a separate cooling system for just the electronics and the MGU. My 2019 KL does not have this but does have the auto start/ stop system using different equipment. Just another example of the complexity of these separate systems.

2015 Cherokee Limited with V6 and 25k miles on it. Start/Stop warning light started coming on intermittently in December. Didn't make a difference in performance so I waited until my yearly service. We put so few miles on the vehicle that I only need to service it once a year,

Found it impossible to make a service appt with my closest Jeep dealership so I went to one about 30 miles south yesterday.

They did a great job of trying to diagnose the problem since they couldn't pull any codes. Technician drove my Jeep home last night with the computer hooked up to it. There were voltage fluctuations and they recommended installing a new battery, which made sense since the original was still in it.

So I'm driving back from the dealership and the Start/Stop warning light comes on!! Even before reading Flyfisherman's post I decided to drive it for awhile to see if the problem continues.

 

Took it back to the dealer today. Apparently they installed the wrong battery. Supposedly the one installed today is the correct one. We'll see if that solves the problem.
