Welcome!

Warranty claim. I had the identical issue with my 2021 Trailhawk. The dealer replaced the battery under warranty in March 2022 with an AGM DieHard.

That did it for me. But it took more than a couple of weeks of relearning -- more like a couple of months. But the system has worked perfectly ever since.

 

[Marek K]

Thanks for the reply. Glad that resolved it for you.

Yeah. Maybe in your case it's also just a matter of longer-than-expected relearning. I was really pissed off too at first that the battery change didn't do it. Let us know!

What kind of battery did the dealer replace yours with?

 

[Marek K]

they replaced my battery with a Mopar AGM

Yeah, as stated, the dealer replaced mine with an AGM battery too. Not a Mopar for some reason, but a DieHard.

Don't know why that should make a difference in this case, but there it is...

 

[Marek K]

It was replaced with a Mopar battery. No update yet but staying patient and optimistic.

Yup, hang in there a while.

What kind of Mopar battery? The OEM battery for my 2021 Tralhawk was not an AGM. But the DieHard the dealer relaced it with, was. And luckydog got a Mopar AGM.

I wonder whether Jeep just figured that an AGM battery is really better for this, and my dealer just didn't have a Mopar one available...?

 

[Marek K]

I'll look again but I recall it looks like the standard battery that was in beforehand. I know it says 36 months guaranteed or something to that effect on the top.

I know your Renegade is a 2022, but here's the original battery that had come with my 2021 Trailhawk -- at least its label:

You can see it was an EFB (Enhanced Flooded Battery), so definitely not an AGM like the DieHard the dealer replaced it with.

And no mention of any warranty on it. In fact, the dealer told me that the OEM batteries are only warranted for two years.

I'd love to see a photo of what your dealer put in...

And again, it's only been just over a week since yours was replaced. Hope you're not panicking yet that the Auto Stop/Start isn't working yet...

 

[Marek K]

Yeah it's an AGM.

Interesting. Maybe for 2022 Jeep figured that an AGM battery handles all the electrical/electronic demands better, and started putting those in. Which might be why my dealer put one in too.

And the fact that my dealer used a DieHard might be because they didn't have the Mopar ones available yet.

I actually have no idea why AGM would be better... Note that my original EFB battery, that supposedly tested bad, actually had slightly-higher specs than your new AGM. And my new AGM has even slightly-higher specs than that...

Nope, not worried about it.

Yeah, I actually don't like the Auto Stop/Start feature. The only reason I got it fixed (other than the Trailhawk being under warranty) was that I hate to have anything wrong with my cars. Once you start tolerating minor faults, pretty-soon you end up with a junker...

 

[Marek K]

Doesn't make much sense why there's no standard.

Well, that's my point. I'm wondering if AGM batteries are Jeep's new standard as of 2022...

 

[Marek K]

Pretty much all FPT engines (especially the turbos) need synthetic oil now.

Pretty much all modern engines need synthetic oil now, as far as I know...

 

[Marek K]

really really hate not being able to over ride it.

Not being able to permanently override it, right? I hear ya...

 

[Marek K]

I'll hack the thing before doing this, hopefully.

Interesting, though I agree risky. Unfortunately, the Renegade isn't among the vehicles offered...

 

[Marek K]

I just got used to pressing the button. Like I now have to do with the damn Lane Assist on the Compass.

Really...? That's interesting, because when I disable Lane Assist on my 2021 U.S.-market Trailhawk, it stays disabled even for future driving cycles.

I really tried to live with lane assist being enabled in some way, but it was way too annoying. Automatically having it nudge the steering wheel back just drove me crazy. And even just the visual alert was annoying.

And no, I'm not weaving back and forth across lanes...

 

[Marek K]

New Lane Assist is extremely intrusive. It grabs the wheel at every opportunity. And resets to on/most aggressive intervention setting every time you press Start.

Yes, the steering-wheel jerking is extremely intrusive. And I just checked; it's LaneSense, not Lane Assist.

There are sensitivity settings through the Uconnect 4C NAV on my U.S.-version 2021 Trailhawk; or the entire LaneSense nonsense can be disabled (permanently) by pressing the button at the red arrow -- amber indicator light shows that it's disabled:

Owner's Manual: "The LaneSense system will retain the last system state on or off from the last ignition cycle when the ignition is changed to the ON/ RUN position."

I just wish my U.S.-market Auto Stop/Start could be similarly permanently disabled...

 

[Marek K]

There's another safety feature that I'm really on the fence about... The Blind Spot Alert. That gives a really annoying sound when I use a turn signal, and there's a car in the blind spot on that side. And, the way I've got it set above, a small amber light in my outside mirror.

I don't mind the light; it's the sound that can be extremely annoying. Mainly because it sounds even when I'm in a two-lane turn lane. I can't remember offhand -- they've got those in Europe, right?

So if I'm the vehicle at the yellow arrow, stopped at the traffic light there with my left-side turn signal on and a car in the other turn lane on my left, I'd be fine as long as the traffic light was red. But as soon as the light turns green and we start moving, the Blind Spot Alert will sound and scare the bejeezus out of me -- even though I'm staying in my turn lane.

I could change the Blind Spot alert to Lights only -- but then I wouldn't have the sound alert when I really need it... When changing lanes when I don't happen to see a car in my blind spot, which does happen occasionally. Particularly here in the U.S., where it's legal to pass/overtake on the right; and a lot of idiots think nothing of doing that at high speed...

 

[Marek K]

On the new UConnect, in the 2022 Compass, this gets reactivated and all settings switch back to default/most aggressive ones each time you start the car.

AND you have to press the button twice to deactivate it.

I really don't see sudden aggressive automatic steering-wheel movements to be a particularly "Safety" feature...

 

[Marek K]

Update, stop start started to work again.

Glad to hear that. This was after you had the battery replaced in January? So it looks like it does take some time to relearn.

I have noticed it works better in warmer weather

I've noticed that too. I assume it's because cold weather puts more stress on the battery, and the system doesn't want to risk not being able to auto-start again...
