One problem related to transfer case has been reported for the 2018 Jeep Wrangler. The most recently reported issues are listed below.
Vehicle was parked and would not engage into a gear. I turned off and restarted and was able to get inrto gear, and engine light was on, it would not get out of 6th gear, brought to dealer and they said transmission needed a re flash, and it was good, next day it would not go into gear, I shifted transfer case from 2h to 4h back to 2h and engine light was on, I was able to drive to dealership. I was told that they are putting in a new transmission and am waiting for completion. I do not feel safe with this vehicle and am looking for a buy back from manufacture, vehicle only has 1,500 miles on it.
