My wife's Buick Envision has that econo stop bs. It's a 2018 and I heard the 2017's and the 2019's had a switch to disable it.
I already replaced the battery but it was 7 years old. I don't think it has 2 batteries like some of you have mentioned.
My 2020 Jeep Gladiator Rubicon Launch Edition
'certainly does 'have a 2nd battery' for the start stop system
&
it's not easily accessible, 2nd battery is buried
under the reg larger battery/fuse/relay panel, all on top of it
when it was bought the start stop system/"eco-mode" BS
as some call it
was deactivated, in the computer program/delete
But then;
after my dad put diesel in it & blew it up at like 12k miles
they ended up having to replace both of the batteries,
both
the large battery & the small batter under it...
We brought it home
the very next day, it's dead in the next morning, I'm pisse
they charged the top battery, told us about that,
I asked even if they did the second battery too, check it
from sitting for over 6 months
"waiting on the engine, during the UAW strikes"
(
now that same Jeep plant is 'almost completely shut down' a bunch of lay offs
or was, maybe the new Stellantis management 'may help save it', not eco-nazis now)
Because
both batteries wouldn't hold a charge anymore...
When they, Sonora CDJR Service did the new engine, injector to pan,
from the Jeep Ohio engine plant
(
they didn't replace both the batteries, as I requested from sitting outside/over the winter,
in their overflow lot for so long, waiting for the new engine, to finally arrive)
but now/after the install;
& they didn't redo/reflash the program/OBD port, in the computer,
to bypass the start stop system, that it was ordered with Delete, from the factory...
(
it's not that tough, but it can wait now too)
Incompetence at the highest service levels...
After waiting for 7-ish months, $14,000+ I didn't want to go back anytime soon
I just delt with it instead...
My elderly dad (
88 in a few days, Feb 12th) is clueless how the **** works too,
keeps starting & pushing the button & stopping it (
then touching the gas peddle)
when he parks the Jeep
Now we, need to push that stupid button, PITA sort of
every time it's turned off, parked or when getting in or out, to go somewhere
sort of a totally stupid system, waste of $$$ to build (
more expenses) & service/maintain it too
but it's not difficult to press the button...
I'd say most that have it don't care for it
but;
it's some useless crap IMHFO
