This issue with the wiring harness and injectors is now linked to the premature engine failure of hundreds of these engines, which results in an immediate stopping of the vehicle in potentially high traffic situations. Neither Cummins nor Tiffin are acknowledging this, or replacing engines unless in warranty.
DEF head failure. Shaw has failed to provide a working solution.
In June 2021 at a milage of 10,630 the DEF sensor become faulty and warning lights came when on I-5 interstate, CA. A replacement sensor solve the issue but the new one also getting stuck causing the DEF level not reporting correctly.
