2019 Sahara dead battery & Powertrain light malfunction

So my 2019 Sahara purchased from the dealership in 2019 with 43000 miles decided it was a good time for my battery to die. That cost me $250 and today I received an alert that the Powertrain malfunction light came on. I have never off-roaded in my life before you ask. Seriously WTF?!?

Powertrain malfunction light.....do you mean the Check Engine Light (CEL)?

Do you know what was good about the good old days? I wasn't good, And I wasn't old!

Found out Grandpa is addicted to Viagra. No one is taking it harder than Grandma...

Ok, so the MIL AKA Check Engine light came on. What are the code/codes you have before getting your panties in a bunch.

It could be something simple, related to the battery change. Scan it for codes and post them up.

Oh, BTW, You have a JL and not a JK. Codes will be the same though except for anything related to ESS, which, come to think of it, might be what your problem is.
