While driving my 2015 JKU, out of no where my brake warning, abs warning, and esc lights flash on and then are off. It happens sporadically. I'm not noticing anything wrong with the drivablity of the jeep. Has anybody seen this problem before?

Is your steering wheel centered while going straight?

You could maybe have a wheel speed sensor starting to go bad, with those lights doing that you can still drive it. Not sure if they have given the CEL enough time to store a code or not but you could check.

This was the exact symptoms caused by the negative battery terminal being loose on our ‘15.
Remove the nut, lift off the tab, and bend the fingers back slightly.
When put back together, having bent the fingers ‘inward’, this will increase the grip on the battery post when the nut is fully seated.
Bad design.
