Stop/Start Not Ready-Battery Charging message.....I know this has been discussed before but was wondering on the highway last night it showed 14.3 volts. Is that normal or kind of a high? (45 minute drive at 76mph) Jeep is still under factory warranty so I'm gonna make appointment to have it checked this week. ....I need to go to the dealership anyway to find out what's taking so long on getting a new radio over the delaminating screen issue.... It's been almost two months since it was ordered. I recently picked up a new front plate I guess it has two meanings

My start stop worked great until last winter. Then it stopped. Always said waiting to warm up then it would go to waiting to charge. Once winter was over and it started warming up it works all the time. It will probably happen again this winter.
As for your delaminating screen, buy a screen protector once you get the radio replaced. Same thing happens to my last Jeep. When I got my GC last year, the first thing it did was buy a thin glass screen protector from Amazon. Best 10 bucks I ever spent. You can’t even tell it’s there and the screen works perfectly like before.

They got me a new head unit in less than a week, just a few weeks ago.

Slap a glass screen protector on it right away.

Not sure why ... the old one was perfectly fine after three years, and I didn't baby it.

But then I've never put a screen protector on a phone either, and never felt the need for one. They always remind me of my high school girlfriend's mother who kept the plastic covers on all her furniture and lampshades.

Ya mine was perfectly fine the first three years. Then after the warranty was up it started peeling and flaking badly. I traded it in that way. When I got my newer GC last year the screen protector went on the day after I brought It home. You can’t even tell I put it on.

OK I will watch out for that. What kind of protector did you put on it?

Here you go.

It seems to be within the screen, not sure if any kind of protector would make a difference. That would just prevent scratches etc. There is another thread about this issue and it seems the 17's and 18s have this problem. It's my understanding this issue was corrected on the 2019 and up models.

That does look a little different. I’m used to seeing a flaky patchy peeling On the outside surface. That looks like some layers are separating.

According to some other posters it's caused by heat. Supposedly they are now using a thicker glass or changed it? A few owners say there units were replaced using the same glass while other said it was replaced by a thicker glass screen? Who knows........

I’m wondering if because of this issue this is the reason they switched to the newer flush mounted screen in 2019.

I just had my 2019 Overland in two weeks ago for its annual oil change and checkup. I told them about my similar problem. Stop/Start quick working several months back - shows that "battery charging" display. Otherwise it starts and runs fine. Never had a problem with a sluggish start. They did a full workup on the charging and battery system. Ended up replacing both the primary and Aux batteries and also the electronic component that monitors battery status. So even though it is sorta nice to have that Stop/Start system fail and quit working (I don't really like that "feature" on my Jeep) when it does go out it is an indicator that something is possibly seriously wrong. Get it fixed.

I don’t know if I’d say it could be something serious. The only purpose of the secondary battery is the stop start feature which almost everyone here hates.
its widely known that those small batteries last only two years. Give or take a year.

Whatever it was turned out to be serious enough that it wiped out the main battery as well and also the battery sense module (the tech said that's fastened to the top of the Aux battery). Fortunately they replaced both batteries and that module under warranty. They said they did a battery analysis (partial discharge followed by a recharge) and the Aux was just about completely gone and the main battery was only holding at 68 percent. Dunno what caused the problem but I'm glad all that stuff has now been replaced. The AGM type battery in my last (2011) Jeep was still going strong at the 8 year point when I traded it in on the 2019. I was hoping the problem with this one was just the Aux battery but it turned out to be much more significant.

Yes you have a good point. But it’s not common for the Main agm to go that soon unless something caused it. The secondary battery does not last at all. pretty much everyone eventually has issues with it. It’s such a poor design and useless feature.
My last Jeep as well had a 7 year old agm still going strong when I traded it last year as well.

Just had my start/stop replaced after getting the message at 29k. Unfortunately out of warranty. 334 bucks for diagnostic test and battery.

That’s a ridiculous price for something that is so easy to change yourself. Did they change the main or start/stop battery? Or both?

This post had me curious this past weekend on what condition my batteries are in. Upon inspecting I noticed the vent tube was not plugged in to the aux battery. All the terminals and mounting brackets were tight And nothing was stripped. A volt Meter showed the two batteries were 12.23&12.17 volts before starting. And 14.53&14.61 volts while running.

It’s worth taking the time to check under the battery cover to see if everything is ok.

Makes me wonder if this is gonna be an every 2 year problem. If you notice on the main battery it says 36 month free replacement! Keep us updated on what your repair says.....

Prety much every battery comes with a minimum 36 month warranty. That doesn’t necessarily mean they will not charge to swap out the free replacement battery.
One important thing I noticed in your pic is that the replacement Mopar battery is made in China. When they replaced my battery last year (with 18k miles on it) they replaced it with a American made Mopar battery.
