Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hello...welcome and thank you for using Justanswer.
I would try to duplicate the smell turning the heat and then the AC ,ON to see if the smell from the vents gets stronger.
Heater core or the AC evaporator can slow leak and give you that smell , you should have it check if there is nothing leak on the engine bay ,like coolant or oil from valve cover gaskets(not very common for this pretty much new vehicle)
Let me know if need any further info.
Thank you very much.
