My 2018 Jeep Wrangler problems

[Mistyrenw]

Why is my clock is always on the wrong time and always some sort of light on the dash coming on. The the battery is always drained. Why are there so many issues? Both batteries The start and stop doesn't work on it either.

Because you need new batteries. What kind of question is this?

When you do as @mwilk012 suggested, make sure you replace both batteries. Alternatively you can bypass / remove the aux battery.

…Both batteries…

Yep you unknowingly answered your own question. Replace both batteries. Or information overload here if you’re interested, starting with the sticky threads at the top of the subforum.

Replace the main battery (if it's the original, consider yourself VERY lucky that it lasted this long), isolate the aux battery and you'll be golden.

Just replaced both batteries on my 2018. Pretty simple job even for non-pro like me.
One tip: whoever does it, have them pop off the passenger fender flare to get access to the small aux battery, it's actually simple and the cleaner way in my experience.
