This icon of the auto start-stop with an exclamation point has been intermittently popping up. It goes away when I turn the ignition off and then on again. What does this mean? Hoping not a trip to the dealership.

There are many threads about batteries, start-stop not working, etc. but in a nutshell I’ve learned 2 things.

1- the battery MUST be a AGM battery.
2- if the battery is correct type, it could be a loose connection at the battery. The battery connectors are a PIA to get tight
3- it could be the IBS going bad on the cable (positive cable I think)

Those are the usual issues for start-stop not working.

Hope this gets you in the right direction! Let us know....

AGM? Now thats news to me! I just walked in at autozone and they gave me a Duralast.

I do remember i was the one who put it in because they super busy that day. Seemed like a lot of car batteries died thAt day from the polar vortex.

Thank you for the inputs. I may have to check battery and connections this weekend.

It's the IBS if your battery is good, happened to me earlier this year on my 2014 before i traded it, new IBS fixed it.

Hi there,

Duralast Platinum = AGM. Duralast Gold = regular, and not for your 2015 (if it has Stop/Start, and it does). Check your bill, make sure you have the Platinum.

A few more things :
- As mentionned above, this type of problem can be related to the intelligent battery sensor (IBS) as well ; the IBS is that big black plastic thing on the negative battery cable just before the connector. If the IBS is faulty, it will cause ESS errors / warning lights. Only a dealership can diagnose the IBS, with their wiTECH scanner tool.

- Battery connectors are difficult to get on tight on these Jeeps because of bad design, so make sure the connectors are tight (grip them and try to move/rotate them).

So first check which battery you have. The battery cover prevents us from seeing battery stickers, so hopefully you have the paperwork to confirm. If Platinum (good) then check your battery connectors. If tight, I would suspect the IBS is faulty...

i may have to take you up on your offer. just had an oil change and mentioned the issue i had with AUTO STOP-START LED Light and the associate helping me was just clueless. he was stuck with the idea that it was a “safety” feature and that it can manually be turned on or off.

although the occurence of the LED light appearing may have been intermittent and sparingly, its still annoying that its a guessing game as to when it will appear and if it does, id have to turn the engine off and back on again.

im just afraid this issue will cause long lasting harm to the vehicle without me knowing it.


thanks for any advice or help you may be able to provide.

Hi again,

Having @JeepCares involved can help at the dealership, for sure.

Can you check one quick easy thing for me ? If you scroll through the center display menu, you should get to a screen where you have a message about why ESS is not functionning (when that indicator light is On). That menu would be : press *down* with your left thumb until you get to a screen with an ESS message. Write it down and let us know, if possible.

About long lasting harm : with this specific problem, it is unlikely. As stated before (back in June), the problem is possibly linked to the intelligent battery sensor, and that sensor's function is to monitor battery health, to allow ESS to activate. It also helps with charging, ddepending on battery state, but charging occurs anyway, without the battery sensor's input, so I wouldn't be too worried. But getting it resolved is a good idea...

If you want to get things moving with the dealership, ask them to check the IBS (intelligent battery sensor) with their wiTECH machine (that's their fancy scanner tool). There is a procedure with that tool to check on the IBS ; quick and simple test...

From what I've seen/witnessed here on the forum, I would be tempted to say it is not a critical situation. ESS is a feature implemented to save a little fuel and produce a little less pollution. But no harm is getting this resolved asap, especially if you are worried.

yep. not a car guy and might as well take care of this and get it out of the way before this say "you waited too long, now this has gone bad.... "

plus, looks like the frequency of this coming up has gotten more frequent rather than sparingly intermittent.

thanks.

My ESS has been out for 6 months. The ESS needs attention light last couple months has been coming on occasionally. I donot miss ESS and always tried stopping w/o it activating. Seems since ESS "gone" gas mileage up a couple MPG?? I have not had the problem addressed on my 2015TH which is off regular warranty. Battery checks up to par, all else seems OK? I have extended mopar warranty which has a deductible and being a true Scotsman hate to use it!! LOL


Maybe next time I use the dealer for an oil change I'll have them check it out? THe last time I used an extended warranty the cost was $69. and the service mgr. asked if I'd rather pay that than the $100 deductible...nice guy!


Go Jeep!!!
