I was one of the unfortunate souls that had a 2014 (6-cyl gas) bought back by Chrysler (after taking a GC sabbatical for three years, I'm happy to say my wife and I took a chance on a new 2016 and now have 20K trouble-free miles behind us with this one, *knocks on wood*).
If I was buying a 2014, I'd just make sure I checked the Carfax and see if it had any major history of issues (things like it coming back in to a dealer many times, or been through three owners or things like that).
I'm a techie, so I always register things online, and I had done so with my 2014 and the Mopar owners' site. After Chrysler bought my vehicle back, I was updating my 2012 Wrangler and noticed my 2014 GC was still connected to my account. It had been sold up in White Plains, and had already been back to the dealer for an issue the new owner had.
I think the problem was that the entire electrical system had been affected by the initial main computer issue in my GC, and I would put money on issues being found years down the road from that initial event where things got fried and/or stressed. I was so glad to be rid of the thing and I wouldn't ever have trusted that vehicle again. I feel sorry for the poor sap that got it next.
I'm sure many 2014's and 2015's are just fine, but there are PLENTY out there to choose from. My only advice would be don't pick one that has a list of trips to the dealer.
