One problem related to carrier/rack has been reported for the 2015 Jeep Patriot. The most recently reported issues are listed below.
Vehicle will stall or completely driving while at speed either highway speed or backroads. I was almost hit by a train because as I was crossing tracks it quit. I placed it back in park and was able to restart it in time. It stalls or quits 8-10 times a day. I have had it at my dealer for the same issue 3 times now. This last time they have had it a month and still continue to tell me they don't know what's wrong with it.
