Hi all,
I'm hoping someone is able to help me. I have a 2015 Jeep Cherokee that when in ACC mode everything works perfect however when I start it after about 30 seconds, "Battery Saver Mode" displays then the Radio volume goes to 0, Heated seats and steering stops working and the outlet at the back goes as well. The screen still works however if you try to turn to volume up it does not go up. I tried upgrading Uconnect and that just made things worst. Now at certain times the screen does not go off after turning the car off. I tired changing the batter but that didn't help. Got the following error when we ran a diagnostic. Has anyone experienced this issue? I'd appreciate some help.

U01B0-87- Lost Communication with Battery Monitor Module- Missing Message
U1008-67- LIN 1 BUS- Signal incorrect after event

Battery Saver mode

Hi,
Exactly the same happened to me recently with my 2015 Cherokee. After a 20 mile trip & leaving the car for a few hours everything returned to normal. Since then all is ok but I am reluctant to put the front & rear demisters & the heated seats on at the same time in case the same happens again

The KL is very sensitive to battery condition and type. The issues mentioned above fit into those caused by a “bad” battery, although there could be different causes too. These batteries don’t last more than three years, depending on conditions they may give up sooner.
Sophisticated load testing is required to determine condition.

I notice that the vehicles mentioned were 2015s, so 3-4 years old. “New battery” may not fix things if the battery is not the correct type. The cheap batteries even of the correct group have proven to fail. The right battery costs nearly $300US. Lots of battery threads here which explain this.

I replaced my battery in June of 18 and is still popped up. Could it be a bad fuse?

So apparently that fixed it??? I had my first battery replaced under warranty at just 14 months old, and the dealer also replaced my IBS. Not sure if it was a problem or not, as the battery was definitely bad...😎

this is the battery it’s a 2015 Jeep cherokee trailhawk V6 and it’s saying i need an oil change and i have one scheduled for tuesday but now my car isn’t starting even with a jump. Everything started last week when i took a trip to bradenton than my battery started dying and getting hot and steaming than it was going into battery saver mode and it caused the volume button and other buttons under the screen to shut off due to battery saver mode and i tested the battery and alternator the battery came up with a code F04 ( which meant that code was saying the battery stops excepting a charge after being charged for 18+ hrs) but the alternator was fine. and after that the battery started to get hot and the little thing on the right side started steaming. and Now my car isn’t starting i’m going to put oil in it to see if that’s the problem but the battery voltage once i get it started stays at 13.6-13.7 which it should be at but i don’t understand why i’m having so much trouble i just got the car the first week of april of this year !

Thanks for the pics and details :)

Did you buy that battery from Autozone yourself ? They come with a 3-year replacement warranty so maybe it's still covered ?
Yeah your battery is toast, you need a new one. Now if the current one is still under warranty, get Autozone to replace it. If it's no longer under warranty, then... you have 2 options :
1) Get the same battery but cheaper at Walmart : the Duralast Platinum (Autozone) sells for $250 while the Walmart Everstart Platinum H7 AGM sells for $180. They are identical. Plus the Walmart battery has a 4-year replacement warranty...

2) If you plan on keeping this Jeep at least 3 more years, you could go for a premium AGM battery like the X2 Power at Batteries+. It is much more expensive though, at $350.

Ok wait a second... just realized something.

That Duralast Platinum battery you have in your 2015 right now is the wrong battery for your Jeep. It is NOT an AGM battery, and it should be. Autozone sells two different Duralast Platinum batteries : one is AGM (that one has double-facing handles on top of the battery, like the Walmart battery I linked to in my previous post) and the one you have, which is a flooded battery (they call it EFB for 'inhanced flooded battery') :

You need an AGM battery for your 2015 because it has engine Stop/Start. The Autozone battery fitment guide got it wrong (we've seen this before).
If you make a good case, they should provide you with a new AGM Platinum even if the current one is no longer under warranty, because they messed up on this one.

Edit to add. This is the Duralast Platinum designed for your 2015 V6 (same as the Walmart battery) :

Just to comment on the overheating and venting of your battery : a Cherokee generates a lot of heat under the hood, because of poor ventilation in there, and the battery sits close to the engine, gets no ventilation so it gets hot. Because you Doordash, you generate a lot of engine heat for long periods of time. An AGM battery has solidified electrolyte (which is a mix of sulfuric acid and water), and because it is solidified it will not boil, so no (or very little) venting. Your flooded battery, on the other hand, can and will boil over when it gets really hot under the hood, so what you saw was real.

Because you Doordash, you really, really... need an AGM battery, the solidified electrolyte is a must for you.

If you have problems with Autozone on the claim, let them read these forum posts. They need to make this right for you.

Now for @rayneee.907 , this unplugged sensor doesn't change the fact that the battery is dead... just wanted to make that clear. An unplugged IBS (intelligent battery sensor) will not prevent the Jeep from starting or running.

Late edit (again) : and just to point out that @rayneee.907's negative battery connector is installed pivoted clockwise, so plugging in the cable would not be possible without pivoting it slightly back, to allow a connection.

Hello Everyone,

I have a 2015 Jeep Cherokee and I am having the same problem. the only thing is I did get a new battery and also I had a mechanic replace the IBS sensor and the battery keeps saying (battery saver mode) and the music volume goes to zero and also when I turn off the car the center console stays on and I wait about 10 minutes and it doesn't shut off.... it is still saying stop/start unavailable... not sure what else to do to fix it, what else can be the issue?

Thank you in advance for your feedback!
