rented a 2015 ram 2500 diesel. Got a message that exhaust system service see dealer. Would run a little rough
JA: How old is the engine? And when was it last serviced?
Customer: 2015 with about 11,000 miles on it, almost brand new. I towed my RV from Denver to NC, filled up tice, plenty of DEF and it started running right so I pulled over due to message

Welcome to JustAnswer!!! My name is***** will be helping you with your question today...

The message means the emission system has an issue witch needs to be addressed with a scantool to see what is going on.. If you have a code for bad DEF fluid then the DEF fluid will need to be drained and refilled with good DEF fluid.. If you have a code for SCR Catalyst performance then we have a software flash to correct this issue.. Since it's new I would have Enterprise rent a car bring it into us(Dealership) so we can get it fixed for you..
