2020 Bighorn 1500 with 43K on it.
No warning what so ever ....
a single issue until this morning. Went to remote start, one bro and didn't start. Got in and all the electronics worked fine but battery voltage was at 10.1v, jumped it, ran fine for about 30 min. Engine light was on during drive. 14.3 during the drive without issues.....Went home, shut it off and 20 min later, back at 10.1 v.....
Edit: About 4 hours later I went out and tried it again. First try nothing. Second try, it had some difficulty but cranked up. Battery light came on, parking sensors unavailable, and that battery voltage stayed at 9.6 - 9.7 and would go no higher.
Shut the truck off, and turned it back on, battery shot to 14.3 and was within normal range, everything working, engine light remained.
Gonna try to have the battery replaced first and see what happens. Hopefully it's an easy fix....
EDIT:
Turns out it was in fact just a dead battery. I live in a very hott climate and the battery just failed to last. There's also a second connection on the positive terminal that was loose and causing it to arc between the connection and the terminal. That's possibly what did my battery in.
