So ESS has not worked for awhile . Always showed " not ready " . I knew from these forums that it was probably a battery issue . Truck has 6k miles , build date
4/2021 . Voltage would be 12.1 / 12.2 after an overnight . Not normal . Service advisor was well aware of the aux battery issues but said they had to charge
the battery for 4 hours before they could load test it . Main battery tested ok , aux was not . They replaced only the aux battery . I see some people get both
as a matter of course .Oh well .
In my research about this I watched a YouTube by [Banned Site] . Highly recommend . He replaced both batterys in 15 min by going from in from the top , removing the fuse box etc . Some comments said this was factory procedure , some said they get in by way of the wheel well by removing the fender liner .
When I got home I thought I'd see if how they did it . Here"s what I found .
Yeah , obviously thru the fender well . Jeez !!!!
I also got a Jeep Cares oil change and made a point of telling them that last time they overfilled by a quart . Got it right this time .
Was told it would take a day or so for ESS start working but it kicked in on the drive home . I don't care about ESS but I didn't want it to take down the main battery
like other people have experienced .
I was wondering how this might end up for lots of people . Would the screws fall out on the garage floor and give them a flat tire ?
Would the fender liner start flapping in the breeze ? Maybe nothing ?
It reminds me of a Dealer experience my sister had with a new car I helped her buy . 10,000 miles and they sold her on a fuel injection treatment for
$200 . I got it reversed with a phone call but so so many people are at the mercy of dealers and shops it makes me crazy !
Rant over !
