As an update, mine hasn't had any more of these issues at all. I just figure it had something to do with the heavy rain we had for several days in a row, but that leaves me curious about the waterproofing of the vehicle.
Light error codes happened to me, took to dealership and it was found to be a body control module with improper ground. All the items that hook to the body were shooting error codes. Replace w new module under warranty so far all good no more codes. Sent from my SM-N900V using ToasterJeep mobile app
This just happened to me today on my 2016 TH (not even 3k). When you took it to have it looked at, was the message still there or did it go away? Thanks in advance!
Message went away after a few miles but took it in anyway next day. Dealer plugged it in and pages of errors came up, couldn't get flash to correct so replaced module. Last week Friend of ours also got no lights errors dealer flashed it went away but within this week it happened again this time dealer replaced body control module too.
