Purchased GC Overland diesel Feb, 2014. Loved the vehicle and used is hard until 2 weeks ago when (at 21,000 miles) I was beset by the same series of issues (DEF) that have plagued many forum members. I was on the road, called the dealership where I purchased the vehicle and which has performed all service. They said they couldn't help me even if I got it there as they were too busy, scheduling 3 weeks out. But...I should get it to a dealer asap...gee thanks. I did find a dealer close to where I happened to be. Though they too were busy, they arranged a rental and sent me on my way promising to have it fixed when I came back through 5 days later. They installed a new DEF pump and I went on my way. 1 week later check engine light and same DEF message. I again called my dealership and was told they couldn't/wouldn't help me...thanks again. I took it back to the dealership that replaced the DEF pump (well over an hour out of my way) and they again arranged a rental and promised they would get to the bottom of the problem and get it fixed. Yesterday, they installed a new computer per Chrysler protocol but apparently upon test drive realized this did not solve the problem. New CAT now on order, to be delivered and installed tomorrow(keeping my fingers crossed).
In the meantime I had a conversation with the service manager at my dealership. He frankly admitted that they simply don't have the capacity to keep up with service demand. Only 2 of his 26 technicians are diesel certified, and given the number of issues with the 2014 diesels they are totally backed up. This is the top selling dealership in Colorado. Jeeps of all shapes and sizes are 'selling like hot cakes" and though a whole new service facility has been promised, so far, nothing. SO if you live in greater Denver, good luck getting your issues addressed in a timely fashion. Thank God for the friendly small town dealer with the diesel tech and rental agency on site. Oh and my extended service contract.
If the new cat does not permanently solve the problem, I too will bail on Jeep. If I'm going to pay a luxury price, I might as well get luxury service. Sure will miss that torque and off-road capability.
