My 2011 Jeep GC has had:
Water pump and radiator both failed.
When brakes are worn almost to end (not hitting the warning yet) they lock up and catch fire due to the poor design.
The heater door flaps broke on both the passenger and driver side. Was able to replace the passenger side. The design was done really poorly as the insulation on the drivers side flap has moved, getting the heater door stuck in heat position.
This is a common problem and the whole core needs to be removed to fix a simple flap door. Worst design I have ever seen.
The lights are constantly needing to be replaced, oem from Jeep don't last long and the HT headlights come on every time you start the car day or night, so they don't last and cost $40 each when I replace them.
There are tons of other problems with hubs, and anti-lock brakes and both of the computers where replaced when it was under warranty. Engine and Light computers (yes a whole box and circuit boards to control the lighting system).
The engine itself has been good, the hemi V8, but so many other issues......
nothing like heat in the summer and getting a long screwdriver out to unstick the pads when smoke starts coming out from one of the wheel wells.
