I have a 2014 Grand Cherokee ecodiesel. This is the most expensive vehicle I've ever owned, the nicest vehicle I've ever owned, and by far the most unreliable piece of garbage I've ever owned. This thing did great the first year I owned it, but has spent almost the entire last year broken down. The best one was when it shut off on me while driving. That repair took 4 months at the dealer and took out the ECU, high pressure injection pump (now a recall), in-tank fuel pump, and possibly started by a crushed wiring harness that runs on top of the fuel tank. Don't see how that could be anything but factory caused. This repair was $6000 and I've now spent $8000 in repairs and its currently sitting dead in my driveway. I've had the DEF system malfunction leave me stranded twice. Last time it drove it overheated only at freeway speeds. Now has new radiator and thermostat but will not restart because of yet another DEF system failure even though DEF tank is over half full of MOPAR DEF fluid. I'm over an hour away from a dealer and last time it cost $700 to have it towed here after dealer couldn't fix it. Now it needs to go back to have DEF system checked again. I can't even get it to start now or I would sell it immediately. I am disabled with MS so I can't just jump out and check things every time I drive it. Code reader will not reset anything to let me start it. This thing is horrible. I will never buy another.
