Ya think Jeep has issues -

Yes, Jeep has issues, Ford has issues, they all have issues.

This sorry ass piece of shit invention was as delightful as a hemorrhoid when it worked perfectly, now at 10,000 miles it decided to start malfuntioning. First it was just the dash light but now it sometimes stalls me out when it jars to life. Can't get into the dealer for another 10 days, how many of you guys have or are currently enjoying this? Anyone know what actually causes this problem and what to expect?

I think it would be easier to just post what your issues are instead of trashing a system that works. Once you understand how it works, you may find it to be just a battery issue. That's not saying that is your problem.

The dash light was most likely your second warning. I know it's frustrating to have a fairly new vehicle crap out on you, I think we are going to have to get used to it. I'm sure by now you have read up on ESS a bit more and figured out how to check your battery voltage. That would be a good place to start if you're looking for help.

Your third sign may lead to a no start and or other electrical problems.

And if it's his main battery dying? jumping to conclusions much......?



YES. TysonGladiator's video.
Here it is for reference, straight to the YT video but he's got a thread here introducing the video as well -



Again - assume much? Could be either, or neither. Could be a connection issue like a LOOSE cable clamp (refer to Tyson's video).

Yeah, it's possible, but "probably" is not as accurate.

Best to check the connections at the crank battery - make sure you can't turn or move the cables - check those ground cable nuts on the IBS, check the IBS clamp and that it fits tightly to the negative battery post, check the positive cable connection.

Charge each battery, test each battery, if they check out fine and charge fine using an AGM charger (several hours, not an hour, good enough - do a full charge), disconnect and reset the IBS, put it all back together.
That'll either take care of things, or you have a battery going bad - could be either, could be both.



That's pretty new for a real battery issue - but never say never. More likely something else going on like a bad connection or you got one of those Jeep batteries that literally fails after a few months.
And if you don't drive it almost daily, and/or if your drives are short, you're not keeping the batteries up full. If it sits over a few days, or if you only drive 10 miles in a trip, you need to consider a battery minder/battery tender type device to keep them full.
Lack of driving, and short drives, can result in battery issues.
And back to always blaming the aux battery - Jeep 4xe's have a history of 12 volt battery failures, some after only a few months. Guess what they don't have - an aux battery.

It's not a lack of drivi

Thanks to everyone for the help, and it's definitely not due to lack of driving, It's very rare I don't drive into the city every day and that's 35 miles round trip at least. As for the people complaining about me trashing the system, I hate these fucking bullshit things even if they aren't technically "failing" I don't believe for a second they make a bit of difference to the environment and even if they have a slight effect they are so annoying I don't care, if that makes me a monster so be it.

Thanks for the help and the video papa, I'll see if I can eliminate a few things before I take it in, what I m still unclear on is shouldn't I have a check engine light if it's an underlying problem causing this rather than the stop start system itself?

I'm not a fan either. It is something that we can't control if you know what I mean. I hate to see someone get upset about technology on modern vehicles. You came to the right place for help.

I mean the system itself is just an annoyance and something I wish never got forced on us rather than an option, but what's pissed me off is this brand new truck having a problem that might be related to my least favorite thing about said truck ?

I was there! Now, I don't even think about it. I use the start stop page to monitor the batteries along with the vehicle info page. Knowing, gives me an idea of how my batteries are. If I see "battery charging" on all of the time, I know it's time to throw the battery charger on it. Still on my 2020 original batteries, but they almost got replaced earlier this year. An IBS reset and a full charge on the batteries has postponed replacement so far. Start stop is available almost immediately after warm up. I don't use start stop, I just monitor the page.

Had the same issue a month ago at 22k miles. Got into the dealer and they replaced the Aux battery under warranty. No issues since.

As others have stated, this is a warning you may / will have bigger issues if not fixed.

 

[Stuntman Mike]

Push the button and turn it off.

Starting procedure for me is: 1. Press brake and start button. 2. Press ESS off button. Always.
And the next modification on the truck is buying JScan and shutting off ESS permanently.

 

[Stuntman Mike]

Thank's. So I'll just continue with my traditional procedure ...

If it’s any consolation, these starters are built for a lot of starts/restarts; my hope is that these starters will not need replaced.

Maybe I’ll date myself, I wish the hi/low beams were still on the floor. I’ve lost count of the times that I accidentally kicked on a blinker when trying to dim my headlights.

Tazer can program the start stop to be off and that is what I do. That way you can still see the ess status and leave the electrical system unmodified with no lights or warnings.
