My 2014 with Air Suspension is headed back to dealer for Air suspension failure. I had the pump replaced last January and that seemed to work for the remainder of the winter, but with extreme weather again this year in North Dakota the problem is back. When I spoke with dealer it continues to be a problem, but guy I spoke with said as of march 2018 FCA approved a new fix of exchanging nitrogen based system for something else seems to have fixed the problem. Has anyone heard of this? This is so frustrating to have the beautiful truck I can't drive without needing a back adjustment after a short trip. I can't believe there isn't a class action suit for this cold weather air suspension problem. Has anyone had this successfully fixed by the dealer? This is a spectacular system when it works for towing my trailer. I just want this to work year round.
