Has anyone been successful in getting Jeep to buy back their 2014 Grand Cherokee EcoDiesel? I think I've reached my limit. We've been into the shop probably a dozen times now all for the DEF system. I have more cases open with Jeep corporate than I can count. The last 2 times were for smoke coming out of the car. Both times they sent us home saying they couldn't find anything wrong even though we had a video showing the smoke. Today the car started smoking again so we just drove straight to the dealership so we could fill their drop off area with smoke coming out of a nice new car while they finally accepted that something was wrong. Surprise surprise, it's coming from the DEF system. They obviously don't know how to fix these problems and they've been there since day 1. Before I lawyer up I'd like to know, though - has anyone actually completed a buy back? Did you have a lawyer or work directly with Jeep to resolve it?
