most of my problems have been smog related have had a lot of recalls and just found out it has two more. to bad about this because I really like the truck. best made truck that I have owned. I average 20 to 22 mpg and most Ove it is in town. I think ram just ran these through past the new smog laws in CA. average 14 mpg towing my 6000 pound rv. If you do drive a lot do not buy a diesel truck in CA. I hope the 3rd generation is better than mine.
