I have both a 2013 Ford Explorer Limited and also a 2014 Jeep GC Limited (V6 4WD) in True Blue Pearl Coat exterior on New Zealand Black and Light Frost interior (photo below).
Between the two, the Jeep is clearly the better vehicle. The Jeep has quite bit of Benz DNA and it sure feels solid. The Ford, well ... <insert your smart comment here>.
Jeep's fit and finish is quite superior over the Ford. Both vehicles are quiet and comfortable but the edge goes to the Jeep. The Ford is clearly physically bigger (carries 7) yet the Jeep feels more roomy inside (carries 5). The Ford is full of small afterthoughts that should have never passed the factory assembly line inspection.
The UConnect system is very responsive but I do not find it nearly as friendly as Ford's SYNC. One could only hope Ford would really beef up the underlying hardware of the SYNC system.
Both the Jeep and Ford however have some of the worst headlights available on mainstream vehicles. I have the halogen projectors for the Jeep and Bi-Xenon on the Ford. I cannot comment on the Bi-Xenon's of the GC.
This inherited version of the GC was the last one to benefit from the Daimler-Chrysler joint venture before they split up and later on Chrysler merged with Fiat. For the wise comment of Uaglio's, Fiat had no doing on this vehicle.
As a side note this is my 2nd Grand Cherokee (I had a 2013 before this current one). The Ford was my first Explorer, but my 2nd Ford product (2006 Lincoln MKS AWD). This Ford product will be my last, the Jeep will be traded in for a GC 15/'16MY.
Enjoy the GC, it will serve you well.
