We bought a 2013 Jeep GC Limited in February, just a few weeks before the 2014's came out. We moved up from a Jeep Wrangler we had been towing for about five years.
We love the GC. No issues. It is very easy to shift into tow mode - put it in neutral and push a button. Then remove the key and you are good to go! Much simpler than the Wrangler, and we thought it was a pretty easy tow.
We have 13k on the new car so far and no problems to report.
