Well I unhooked the battery over night. Everything was fine for about a week. Just happend again. Not sure what to do next. Unhooking the battery every 1-2 weeks isnt the answer. Trying to avoid bringing to stealership :/

Sorry to revive an older thread, but have you had the same issue since then? My Jk is doing the same thing but my codes are a little different. I’m getting a C121C, P2638, and P0369.
