2017 RAM with 6.7 Cummins. At 38K miles I had a complete DPF failure. Ran like S$%T and barely fgot to the dealer at 20 MPH. The Filter had cracked and had to be replaced. It was under warranty. Just prior to total failure the dash read "Exhaust System Service Required. See Dealer" Owner's manual suggests that this means the system has quit working entirely. Same message came on weeks later and at 42K miles, but now out of warranty so I took it to my preferred repair shop - not the dealer. They performed an ECM reflash and the code went out and the dash message did too. Now 5 weeks and 1,000 miles later I got the code and message again. WHAT THE HELL???!!! Anybody know what is going on. I sure don't and apparently 2 shops can't figure out what is going on with my DPF system. Any suggestions?
