Start stop and traction control

[Roccco]

I have a 2018 Wrangler JL and the stop start light and traction control light come on every time I drive . Tomorrow to the dealership they said it was the aux battery. Replaced and the problem still exists. Took it back to the dealership I was then told it was the vacuum pump. Replaced and the problem still exists. I was driving the other day everything worked for about 20 minutes and then lights came back on. All the dealership is doing is guessing what the problem is at my expense.
Does anybody have these issues and have an answer?

Do you tow this behind a motorhome 4 wheels down and have a demco air force one brake system installed?

I do, and on mine it was a vacum problem. I cleared the one way check valves on the demco brake system and pulled the breakaway switch for a couple of minutes. One or the other cleared both start stop and traction control dash displays.

Before I tried that dealer, dealer tested primary and aux battery, replaced main battery, changed vacum pump and vacumm sensor. No help, but I think they were on the right track with a vacumm issue.
