Two occurrences of catastrophic engine failure leaving me stranded on highway fearing for my life. First event dealer had Jeep for 5 months to "replace motor" I had to contact them several times after getting it back to obtain documentation and was told original warranty of 100k miles would be renewed. Recent second occurrence at 60k miles on new motor dealership has now had vehicle for over 2 months. Now trying to charge me for high pressure diesel pump they replaced, car still not running. Plan to replace all valves, will it run? initially it had shown so many codes they couldn't determine why the car failed. Nhtsa has over 130 complaints on this motor. Jeep fiat Chrysler awaiting govt. To sign off on emissions scandal settlement that will allow them to not have to buy back this vehicle, unlike Volkswagen who did the right thing for same issue and bought back. Unlike Volkswagen this vehicle has multiple documented defects and safety issues. I am being stonewalled by Jeep for resolution. Since my purchase of this Jeep in 10/2014 it has been in for repairs unrelated to normal use more times than I can count, over 7 months in shop while I am paying on it without being able to use it. I purchased this vehicle for reliability, it has failed that test over time. They could again replace the motor and I do not want the vehicle back, I will not again risk being stranded on the highway, engine nearly on fire after shaking, knocking, rocking, and smoking not able to turn off until it dies. I refuse to resell it to some unknowing unsuspecting person that will end up with a lemon if the dealer gets it running. This Jeep needs to be recalled immediately before someone loses their life! Jeep and the dealer service departments need to be made to stop defrauding consumers and making millions on a defective lemon. I have never had so many issues with a vehicle in my life. Help!!!.
Engine failed. The engine (5. 7l hemi) failed in middle of six lane road. Fortunately not much traffic around vehicle when engine failed. If this happened on interstate it could have a substantial safety risk. Mechanic reported the engine lost a rod and damaged the block. Since vehicle under warranty, the engine was replaced. Only 47000 miles on engine.
