2016 Jeep GC overland/ high Altitude. 68k and am now, I believe since the diesel recall reprogram, having issue s with the filter. Whenever I tow (we tow a 4500 lb travel trailer), the next time I drive the vehicle I will Get the dreaded filter regenerating then sometimes filter full. Once had to go to the dealer as it hit full. Could this be related to the reprogramming that occurred as the recall? Anyone else experience the same thing. Why, now am I getting this whenever I tow? I can tow for a 4 hour highway drive and then the next day have to go joyride on the expressway only to regenerate. This never happened previous to the recall. Or is it a mileage issue?
