Any Chrysler Techs out there?
My dad worked at Chrysler you retired a couple years ago and I noticed I was having the same issue that you're having in my 2013 Dodge Caravan and will misfire on me randomly while on the freeway. Took to the to the dealer bunch of times they couldn't figure it out they changed a bunch of parts under warranty after 10 times I called a lemon law lawyer and they bought the vine back from me. It's somewhere in the wiring harness that went bad or got pinched during manufacturer that's what I was thinking what happened to my van because nobody can figure it out and I took money to Four dealerships even my dad could not figure it out and we have the scanners on it while driving. My opinion is if it's still under warranty keep taking back to the dealership after 10 times they cannot fix that problem you do by law have the right to get a lemon lawyer law and have them by the vehicle back
