3.2L Diesel Fuel System Problems

I have a 2015 3.2L diesel. I keep getting check engine lights for low fuel pressure, error messages about the fuel filter clogged service required. The dealership replaced the fuel pressure regulator that didn't fix it. Another dealership tech said they are having problems with the fuel system problems but they are still so new they don't know much I just have to leave it with them. That sucks this is my handicap van and my only means of transportation it only has 3,500 miles. I checked the recall for the fuel pump my van isn't on it. Has anybody else had any problems with their diesel van?
