Hello, I have a 2014 jeep Cherokee trailhawk with 120,000 miles on it. Recently I went to take my jeep in because I'm no longer able to put my jeep into 4WLOW . Turns out I need a new PTU due to bolts backing out/ missing on it. I took my jeep in for the w47 recall. Sadly my jeep isn't under warranty is there anything else I can do to get the dealership to help me get this part repaired due to the history of these PTU failing?
