Think battery life can be extended by turning off ess every time you get in the vehicle?

Hahaha... trick question :laugh:
Honestly though. In theory : no or very little. But with these undersized (and a little crappy) Johnson Controls AGMs, there's a good chance ESS would drop a few months longevity on them, depending on your driving environment and habits, of course. We've seen plenty of V6 2014s with early battery death, yet they don't have ESS (but don't have AGMs either).
So yeah hard to say, really... But with a quality battery (like a thin plate pure lead AGM), I'd bet ESS doesn't have much of a negative impact on battery life.

New battery did NOT fix the problem. Photo taken about 48 hours after new battery. The problem I have with lame service techs is that they never drive to root cause; they only do the bandaid approach. /images/JeepCherokeeClub_Toucan/smilies/tango_face_sad.png

Does your dealer know what the IBS is, and how to test it with their wiTECH tool ? That would be, to me, the next logical step.

Apparently I needed to wait 72 hours for the SHM to fully work. Who knew?

Well... whoa. I'll try to remember that one :wink:

Hi,

You started this topic last year. As far as I can tell, your last post regarding this issue was a year ago, and you were supposed to visit the dealership. You haven't posted since. We had mentionned getting the intelligent battery sensor tested (dealership).

So... did you hold off on that dealership visit last year, and if so why ?

 

[Xtain1206=]

Life got in the way and Winter. seemed like occurrence was way less winter time.

also verified in one of my visits to Autozone that they did give me the correct battery.

thanks

Thanks. Battery is likely the correct one then (Duralast Platinum H7). We ask because some battery fitment guides get it wrong, suggesting a regular (wet) battery for ESS Cherokees.

Ok, so a dealer visit seems in order, for sure. Do mention the intelligent battery sensor could be off spec, they can quickly test it with their wiTECH machine.

So will that permanently fix it? will they be able to fix it right there and then or do i have to leave the car, get a rental and wait for them to fix it?

thank you again and sorry for going AWOL. i did not imagine this THREAD will get 4 pages and worse i started it. thank you again for your patience. ill be monitoring and giving an update. PROMISE

No worries. Forum threads tend to get... off track a little bit or, more often than not, others will drop in with a similar problem and the pages add up, haha.

The intelligent battery sensor (IBS) : testing for this takes all but 5 minutes. They hook up the machine, scroll through a few menus and boom, they get the results. Replacing the sensor (if necessary) is an easy job ;don't know how much time exactly, but under 20 minutes I'm sure. Problem may be availablility : most dealerships may not stock this part, so if they need to order one, you'd have to go back (they don't have to keep it in the shop, you can drive away with a bad IBS. Last I heard the IBS sold for roughly $150.

Keep in mind : the IBS is on the suspect list for now, only the machine (wiTECH) can confirm if it needs to be replaced.

and this is covered with my Mopar warranty or whatever its called? and the wiTECH machine is standard equipment in a Jeep dealership? sorry im just anticipating how they (dealership) will try to screw me, this way i know how to counter whatever nonsense i get.

Uhm, unless you have an extended warranty plan, this would not be covered. Jeep warranty for your 2015, for anything not powertrain, was 3 years/ 36 K miles. Powertrain is (was) 5 years or 100K miles, whichever comes first. Electrical stuff like this is not powertrain, so only something like a MaxCare extended plan would have your back here.

wiTECH is a machine (scan tool) used in Chrysler/Jeep dealerships by technicians, to communicate with all the electronics/computers in our vehicles. This machine can detect and fix issues, like IBS issues for instance.

As far as the dealership trying (or not) to screw you : sorry... we can only go so far with help on a forum like this, we have no control over what a dealer might do. However there is possibly help for you, there are folks who work for Chrysler/Jeep who hang out on forums like ours, looking to help customers with dealership visits. They will reach out to dealers to try and have things go smoothly for you. So I'll get their attention : @JeepCares if you read this... someone may need your help.

 

[Xtain1206=]

Thanks. @JeepCares was kind enough to offer me help awhile back.and already pm'd @JeepCares. I do have the extended warranty.

Looks like there's no reason this dealership shouldn't have what they need.

so i took time off to take my jeep to the dealership as scheduled thinking that i get the issues with the START/STOP LIGHT turning on intermittently resolved. of course to no surprise i came out of the dealership fuming mad.

i thought with @JeepCares providing me with a case number and telling me from our conversations that my case was being escalated MEANT this was being communicated to the dealership. WRONG never was the case.

when i got to the dealership, they told me that I had to leave the jeep and wait for them to call the next day to tell me what the result of the diagnostic tests they did. i did bring up @Mark_ 's initial thoughts of a 15min check of the IBS with the WiTech and the smart alec service rep told me yeah the WiTech will take about 15mins BUT there were other Battery tests that they'll have to do and proceeds with technical mumbo jumbo. and also tells me he was sorry and NOT TO use online scheduling as it was not functioning properly (i.e. they don't get notified when an appointment has been set.. which is BS for me)

the service rep goes on to say since i have extended warranty but will have a $100 deductible. if what @Mark_ 's $150 estimate is true for the part, i am now thinking to just live with the fact that this darn light is going to light up whenever it wants and if it does, it wont diminish the jeeps functionality.
OR
perhaps go to a different dealership as i have considered Parkway Chrysler Dodge Jeep RAM: New & Used Car Dealer in Clinton Township, MI to have sketchy service from the start (my jeep is at 100k and i do not remember them telling me it may be time for a routine maintenance... another thing i have to look into.)

wish @JeepCares do a better job helping.

just happy i did not make the same mistake and put into consideration getting a FIAT/CHRYSLER vehicle as a replacement to the wifes van. thank you @Mark_ for your inputs any further advice will be very much appreciated.

Just wanted to say thanks for this thread. Recently had the same ESS warning light randomly pop up on my dash and a quick google search brought me here. After some reading I figured it was going to be the battery or IBS and sure enough, the dealer confirmed by telling me I needed a new battery. Took about 10 minutes of driving for the ESS to reset, but all good now.

Welcome to the forum

For the last few months I've had the Start/Stop not available, battery charging constantly on. So, with just over a month left before the factory warranty expires, I got it to the dealer to have it checked out. They checked it out and determined that the IBS was the problem and replaced it. Dropped the car off night before, the service rep contacted me the next afternoon with the test results and said they needed to order the IBS and replaced it the next day. Hopefully, this will fix the problem and it's not the battery.

This is the only issue I've had with this Jeep and can say that my local Jeep service department has been great to work with on this problem and have never had any difficulty with their "Express Lane Oil Change" service in the past.

WooHoo ~ one for the dealer!

Here's an interesting thing that I will report after taking mine in for a suspected bad battery this week at a new dealer. (I've dealt with my prior dealer since 1990, but have since moved, and although I wouldn't say they were perfect they knew me, and would work with me without trying any funny business. However, they are now 30+ minutes away, and I have 2 dealers within 10 minutes from me now, so I figured I would see how one of these dealers is.)

Although the service advisor tried to get me to pay a diagnostic fee and upsell me on some "semi-annual" service package, that all went away when I said that the battery was replaced in November 2019 at another dealer, and I'm fully covered by a Gold Plan after my current basic warranty runs out. (This was despite the fact that he had the VIP report in his hands that shows this, and could see the last service visits at the other dealer) He then proceeded to call the other dealer and ask for them to send over a copy of the invoice where it was replaced under warranty. Once he had that, the semi-annual service package wasn't mentioned again. Super sketchy IMO.

Anyways, they hooked it up to the GR8 battery tester and all is well apparently with the battery. Then I noticed in the tech notes that they disconnected and reconnected my IBS. Prior to this service visit I was seeing weird things with the charging voltage, 14.4 or 14.5 while running, and below 12V on ESS restarts. Ever since the IBS reset, it's been charging at 14.0 and restarts have been above 12.X. He also proceeded to read me the list of ESS conditions from the owners manual that would prevent it from activating, even though I've told him that it's consistently been a "battery charging" message for the past several months.

All in all, I'm not sure I will go back to this new dealer, but maybe he is new, as he had to ask the lady at the desk next to him how to even enter the issue in his work order system.

I'm thinking the IBS may be some of my issue and it wasn't fully tested in the past? Perhaps I will try disconnecting and reconnecting the IBS in the future if this ever happens again?

I'm keeping my battery on a trickle charger since it's not being used that much now so we'll see what happens.

Hmmm. My guess is the IBS disconnect/reconnect is merely an attempt at forcing it to relearn, nothing else. The IBS can be reset, but this has to be done with wiTECH, not the GR8 machine. wiTECH can report an out of spec IBS and it is a simple test from what I've heard, so... I don't know why dealerships won't go that route quickly, to rule out the IBS.

I forget, but did you ever buy that little Ancel BA101 battery tester ?

Not 100% sure here, but I think even the GR8 machine can report healthy (above 50% health ?), while not healthy enough for a KL... which requires roughly 60% minimum health for a working ESS.

Yeah, I wonder if the IBS had become confused or something, and the reset will make it better now? We'll see.

I actually forgot about that tester, I should get it so I can test it myself before going to a dealer.

I did buy a Genius battery maintainer to keep on both vehicles however.

My battery failed not too long ago, and when it was in bad shape the automatic start/stop turned itself off. The new battery resolved that problem.

However, a few days ago I found another cause for auto stop/start disabling itself related to the hood open/closed sensor.

I had popped the hood release but forgot to actually look under the hood. When I pulled out on the road, the dash flashed a warning that ESS was disabled. I thought the battery must be failing again, so I pulled over to make sure because I was heading off-road and didn't want to end up with a failed battery in the middle of nowhere. As I stopped, I remembered the hood, closed it, and turned off and restarted the Jeep and the problem was gone.
