I have owned diesels since my 2008 Grand Cherokee. Never had a problem. Great fuel economy. Have had them start at -35C -31F The diesels of today are far different from those from years ago. I won't own an SUV without a diesel!
Coming from an ' 04 4.7l h.o. motor to the diesel is great. Yeah I got less "go fast", But i went from $60ish in gas a week to $80 every two weeks. Good trade, also got 0 issues so far. 2500 or so miles on it.
