Funny but I've worked at Ford, GM and Dodge service dept's and they were all full of vehicles needing repairs. I've seen Ford trucks with the bodies off to replace a powerstroke, I've seen a Lumina that lost its engine on its PDI roadtest, and yes I've seen numerous Dodge auto trans failures and 5th gear nuts come off the diesel 5 speeds.
Bottom line is any vehicle can be junk. My last 2013 Ram had MIL issues, always coming on. Pizzed me off and I traded it at 14000kms and got a 2014 Ram, identical except its white. Trouble free so far. And less work than my black one to clean
