Abs light, traction control off, esc off, check engine light

[OreoJeep]

Hi jeep fam! I know today is sunday and i think most, if not all service departments are closed so i was looking here for advice in the mean time.

Tonight while driving on the freeway, i got the "Service antilock brake system" and "Service Electronic stability control" messages popped up. My check engine light is also on. 2500 miles on my 2021 jeep wrangler jlu. I did get it lifted about 2 months ago to a3.5” lift, 35” tires, 20” rims.

Any ideas what could this be? I did have it in the shop about a month ago with some type of fuel emission leak. Thanks in advance.

Could be 1 or both batteries are dying! have seen many posts about batteries premeturely giving up the ghost and causing electronic gremlins. Take it over to a battery place or auto zone and have them do a test on the battery up top...I'm not sure how to test the lower since it is concealed.

Almost certainly a battery issue. Have both checked ASAP so that you don’t potentially get stranded somewhere.

Also FYI I had started to get the ESC(electronic stability control) signal along with the stop/start service message and a very helpful member (mwilk012 posted this to my issue.....
Steering angle is an input to both ESS and VSC so seeing that you have been in there you might have them check that ..... when I was at the dealership I had them load test my batteries and both were fine so this will be my next appointment .

Bad batteries will cause gremlins, but since you mention the lift my mind goes to the ABS system...seems like a sensor wire may be pinched or broken somewhere. Start by looking underneath at all 4 corners.
