2021 3500 Hard to start and Exhaust System requires service message
My 2021 RAM 3500 Longhorn Limited Edition is suddenly hard to start and after starting the error message came up saying the exhaust system requires service. Any idea what might cause this? The dealership I bought it from can’t even get me in for another 5 days. Is this a regen issue or something...- JimE63
