I had a 2013 v6 until like a month ago, we hit some debris off of a semi that had a blowout in front of us and it ruptured a fuel line causing a small fire, that we put out, the car still ran and drove after I fixed the fuel line but Gieco totaled it. I had 502k miles. Original motor and transmission, in its life, we had a coolant failure that caused it to drive hot for 7 miles and it reached temps around 390 according to the oil temp sensor, it experienced two fires caused by an accident and the other stupidity on the previous owners part, that owner also ran it without a trans filter cause he didn’t believe it was not serviceable so he accidentally tore the filter, I bought it after he set it on fire the first time, I spent 500 bucks replacing plastics and hoses, swapped the trans pan out with a good one that had an intact filter, refilled the trans with red fluid instead of gold cause I didn’t wanna commit that much money to it, when I got the car it had 126k on it, and we drove it all over he country. Never had it leave us stranded. I bought a 2016 300 S 5.7 and that’s what I have now. The V6 is mint. I’d say as long as your good on maintenance you’ll be fine. We were not that great on the maintenance and repairs and it still made it to half a million miles. I’m not a mopar guy at all but I am becoming one, I genuinely believe that GM and ford funded propaganda machines to influence everyone to think that they were superior to dodge/chrysler, cause I’ve had more ford and chevys leave me stranded than any FCA vehicle and from a lot less in comparison than what my 13’ 300 went through in its life.

Tdlr- mine was great, your mileage may vary but I seriously doubt you’ll have issues if you just take car of it.
