I am looking at buying a 2014 jeep grand cherokee. The eco-diesel caught my attention mainly due to the power and mileage. I never had a diesel so there is a big unknown there for upkeep and longevity. If I stick with a gas model it will be the 5.7 Hemi. I have read about the diesel on the jeep forums and there is a lot of negative so that is throwing a red flag. Anyone have some input or opinions on the eco-diesel? I did test drive one and was very impressed with the power.
