2021 3500 Hard to start and Exhaust System requires service message
This is where it gets really interesting. This afternoon when I went to move my truck to make it easier for the tow truck, it started right up and the check engine light is now off. It’s also running almost like normal.- JimE63

2021 3500 Hard to start and Exhaust System requires service message
Would this still be the case without A DPF warning light on the dash? I guess anything is possible in that regard but all I have the the check engine light on and the engine sounds real diesely, if that makes any sense.- JimE63

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
