Hey folks
Have a weird occasional issue with starting on my 2018 JLUS (25,000 miles). It will crank and crank without even sounding interested. If I stop the cranking after about 15 seconds (push button with foot off brake) and try again, it immediately fires right off. Doesn't do it all the time (especially while it is at the dealer!!). Dealer said to try different gas (sigh...). Have tried to capture video, but the car must have some sort of "uh-oh, he's watching" sensor so it behaves. Thoughts?

Good point... mainly after sitting overnight.

What are people doing regarding the second battery? Is there a beefy replacement? Can it be deleted and forced to pull off the main battery? Is there a kit for that? Having a second hidden (hard to replace) battery just seems weird to me. V6, Automatic, Sahara, 2018
