St. Charles CDJ is the only dealer that actually fought Chrysler with me on getting our van repaired when it was sucking down 4 quarts of oil (on a 5 quart sump) in <2,000 miles. Bill Kay in Naperville (where we originally bought it from) before they were closed pretty much brushed us off, Feeny (or now Elgin CDJ), kept putting me through oil consumption test after oil consumption test and then claimed nothing was wrong.
So this one is pretty fair. I've dealt a lot with them between both vans. Among the numerous little things that have gone wrong on them, they've replaced the engine and trans in the old van (under the lifetime powertrain warranty) and replaced the entire valvetrain on the Pentastar V6 on the '15.
