Electrical Issue

[Arcticpiper]

Anyone have this happen:
About once a month, my radio resets. I start the jeep, radio is off (didn't turn it off), turn it on, and all memory is wiped.
Also, abs light will come on and the breaks will grab occasionally. Then the light will go off. Only seems to happen when using cruise control. Had the sensors replaced last September.
Think it's an electrical issue. Jeep is a 2017 Unlimited Sahara.
TIA for any info.

Does your 2018 JLU Sahara, still have the original 2 batteries in it, that it shipped from the factory with?

If so, undoubtedly your issue is directly related to iffy batteries.

Replace both the Main and Aux battery on your 2018, asap.

My wife's car radio reset like that right before the battery completely died, for the year of auto it was supposed to last 2 more years but the dealership pulled a bait and switch on batteries.

Before you pull the trigger on replacing the OEM batteries I recommend you read through the threads on the Genesis Dual battery kit. There’s lots of discussion of electrical system whackiness when batteries are low, and ample discussion of the options, pros, and cons of using the full Genesis system. The hybrid solution of using the Genesis tray and configuring the batteries in OEM arrangement may be the best solution for some folks; it’s not super expensive and it allows easy future access to both batteries.

I disagree on the Genesis stuff. For most guys it is overkill at best and more of a waste of money.
This guy has a 2018 Sahara. IF he has done just fine with his stock set-up for 3+years then undoubtedly he is not a candidate for a pricey dual battery set-up.

IF a guy / gal has a clue the stock dual battery system is not the disaster some guys claim/whine that it is.

Really? What's the downside of the tray-only solution, (with the factory wiring configuration, so both batteries are easily accessible?

@Whaler27

Why would most guys/gals need to spend a hundred(s) to well over a thousand for a pricey aftermarket offering.

Whether the offering you purchase is just a tray or the full blown dual battery system......for most it would be $ foolish at best.

For a few, a handful, YES well worth the $ but again, for the majority it would be foolish to spend such money.

Reality is the same guy/gal that is clueless in regard to the stock dual battery system will be just as clueless with the pricey aftermarket dual battery set-up. MOST don't maintain or understand whatever they have and that is why they have battery related issues. Wouldn't matter if they had bigger/better batteries, a tray or not.

In closing, learn about your set-up.... take care of and maintain it, slightly modify the stock dual battery set-up is all a guy / gal needs to do.

As for accessibility of both of the stock batteries... To me it is not that big a deal to access the Aux battery.

We'll have to agree to disagree.

For those who don't want what some describe as "overkill" for the full $600 Genesis set up, there is a tray-only purchase available for about half that. (I'm not adding the cost of new batteries, because batteries eventually have to be replaced regardless of where they're mounted in the Jeep.)

All batteries die, often at inconvenient times, so it's nice to have easy access to test and replace them at the nearest Walmart, Costco, O'Reilly's, or Batteries Plus. Replacement doesn't happen conveniently or quickly when the battery that needs replacing is buried three layers down underneath the fuse box -- especially if the battery is an unusual size that isn't in stock at most auto parts stores.

I agree that batteries need to be maintained properly, and many folks are poorly informed about what that actually requires, but that only underscores my point. These are the same folks who are most likely to have a battery fail prematurely and unexpectedly, and they're the same folks who aren't going to be eager to disassemble their fuse box and dig down to the aux battery (or remove a tire and go through the fender well to access the little battery) while they're on the side of the road.

I wanted the extra battery power from the Genesis system to help with all of the accessory load I have, but the biggest benefit, for me, is the redundancy and easy/instant access to both batteries. If I screw up, or a battery fails prematurely, I'll be able to find a quick and easy solution to get me home and finish my trip. Given what most people spend on wheels and tires alone, I think ~ $300 for a new battery tray is a cheap insurance policy.

I just got my JL back from the Jeep dealer after a reflash. While there I spent some time with two of the service writers, as neither had seen the Genesis system. I shared the pros and cons from my perspective, and they shared their persistent problems with the little OEM battery. They hate it, because a majority of their customers don't know about the unique battery configuration until they're stranded with strange electrical behavior (or no electrical behavior). When the customers learn there's more to the fix than there was with their CJ/YJ/TJ/JK or 4-Runner, they're grumpy, because a quick trip to Walmart won't get it done anymore. The service writers want a system that's more traditional and idiot-proof -- because that's what their customers demand.

No need to say more... I know my stuff so to speak in regard to this topic.
People can read forum posts / research, etc.. and decide what makes $ sense to them...

Not sure how you figure a guy / gal can have purchase that particular "full" aftermarket dual battery set-up and two decent batteries for $600. And then most would pay at least say $200+ to have it installed..

Also tray for $300 plus batteries and install is not $300 total for a tray set-up.

Anyway, redo you math.. Full system even if you install yourself can run $1100+.

Tray alone is $300. Plus you need to buy batteries and most will pay for the install.

AS I SAID....
For a few, a handful, YES well worth the $ but again, for the majority it would be foolish to spend such money on an aftermarket dual battery system or a tray

No more posts from me on this. 8-)

I won't debate further, but will explain the point I somehow managed to confuse: People who are about to replace batteries, like a guy experiencing problems with his four year old batteries, are going to pay for new batteries whether they're replacing the OEM batteries in the OEM positions, or they're buying batteries to sit on a new tray where they're easier to access. So it makes no sense to suggest the battery cost is an additional cost that comes only with a Genesis tray option.

Installation of the tray takes a little time, but it's simple, and there are good step by step video instructions online. Nobody who would have to pay for that installation is going to be able to replace the small OEM battery on their own in the Walmart parking lot (or wherever).

To each their own but when I replaced my dual batteries I seem to recall the Genesis system compatible batteries being considerably more expensive than replacing the stock ones, in addition of course to the cost of the Genesis tray.

Good YouTube video had me prepared with tools and technique I needed to replace the aux battery from above and isolating the batteries is far more cheaply done here: https://www.jlwranglerforums.com/forum/threads/ess-dual-battery-management.60034/
