Gas Recirculation Valve (egr Valve) problems of the 2016 Jeep Grand Cherokee

My 2016 Jeep Grand Cherokee 75th edition 3. 0l ecodiesel stalled with no warning while driving on a two lane highway in the middle of nowhere, new mexico. No warning lights, until the entire dashboard turned on and the car starting losing speed and power. I don't know how I was lucky enough to make it to the shoulder. I sat there for 2 hours with my 2 kids in the car waiting for a tow, 8 hours from home. I have come to find out that there is one recall for my egr but when taken to the dealership I was told that my car was built with magnetic material attached to the tone wheel which provides a signal to the crankshaft position sensor and was lost therefore leaving me stalled and stranded. I have looked up my recalls and that one is not on there! how is that possible.

While driving the vehicle and towing my boat (approx 4500lbs) for the previous hour or so on state highway between 50-65 mph with some stoplights (not interstate), the check engine light (cel) came on and the driver interface on the instrument cluster came on displaying something to the effect of "service electronic throttle control system". Continued driving approximately 2 miles to get to an intersection to turn off the main road. Once stopped at the stoplight I noticed slight smoke coming from the left front corner of the hood by the headlight. I placed the vehicle in park, put the hazards on and pulled the hood release. By the time I exited the vehicle and made my way around the door to the hood, thick black smoke was billowing from all around the hood and flames were noticed coming through body gaps and the grill. Within 30 seconds the entire engine bay and hood was engulfed in flames. I did manage to get the boat unhooked and pushed back and documented with photos. This is the third time these indications (cel) and driver interface displayed the exact same indications. The first time it resolved upon shutting down the vehicle. The second time, it was brought to the dealer. Approx 1 month prior to the fire the dealer found nothing on inspection and reset the code. The code was for excessive egr flow. Additionally the dealer performed any outstanding recalls on the vehicle. This vehicle was equipped with the 3. 0 eco diesel engine and was bought new, dealer, serviced its entire time and had approximately 70k miles on it. I have no doubt this was directly rated to an egr problem that these particular engines have had issues with directly resulting in the fire.

Severe bucking & jerking while driving. More moderate bucking while car is idle. Codes being thrown are p0406 & p0301. It has also thrown a p0402 as well. I've replaced the egr valve as well as all spark plugs and the problem still has not been solved. My fuel mileage is tanking and driving the Jeep has become almost unbearable.
