So on my way home i was driving about 70 on the highway and my JKUR down shifted and red lined out of no where. when it red lined the check engine light came on. took it to the dealership they said nothing was wrong. about a week later the check engine light came on again and it wouldnt shift to 5th gear. took it to a different dealership and they said it was a problem state wide with the 2015's and all they can do is clean the cylinders and wait for JEEP to find a fix to the problem. and that im on a long waiting list. does anyone else have these problems or know what it might be? thanks in advance!
