Chrysler Minivans are the only Mopar product that is not a raging dumpster fire of reliability woes. Maybe the Ram escapes that generalization too, as the minivans seem to be the one place they don't shaft their products as much. Still, they cut corners and you will notice that issue. They cost less initially and will cost more eventually. The only way they could be worse if "Fix It Again Tony"- FIAT got their hands on them... wait...
Still, you could not make me take one for my personal use. I have seven 7 in my fleet. They are not "bad" vehicles (I hate the old Chevy Minivans more) but considering other options in the mix, I would go with a Kia without a blink of the eye. Dodge minivans will limp along to high mileage but it will be a lot of "should have lasted longer" type of repairs as someone has mentioned them eating brakes like halloween candy.
Kia is 4th (really 3rd as they counted Toyota twice) in Consumer Reports for Minivans, Dodge is dead last... 9th of 9. Kia is only behind Toyota and Honda's offering.
Also, some of the feedback about the new 2015 I have in my fleet is that they are not very comfortable for longer trips. This was kinda a shocker. The old 2006 minivans were fine. My main employee that handles most of the day-to-day work ranted like a mad goat about having a 500 mile roadtrip in those seats. Maybe the trip level matters but those older vans were strippers and were fine. The new vans are mid-trim level so I don't know what to say...
