NHTSA complaint 11692155Two issues, both resulting in derating to 5 mph on a busy freeway. The DEF sensor has had repeated failures, resulting in 7 generations of DEF sensors, all of which have had repeated failures. Without reprogramming by Cummins, a DEF simulator, or DEF sensor replacement, the engine derates to 5mph upon 2 restarts. This results in a dangerous driving situation unless the vehicle is towed. The second issue is a faulty wiring harness in all Cummins ISV 5.0 engines, used in Nissan Pickups, buses, and Tiffin Breeze motorhomes from 2017-2019. The wiring harness was designed with injector wires that were too short, which caused injectors to intermittently fail, causing the engine to derate on the fly, causing a dangerous driving situation. In June of 2022, Cummins issued a TSB regarding this but no recall was initiated. 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. For Tiffin Breeze motorhomes, 3 of the 2017 engines have failed just after warranty expiration that I personally know of. This has occurred in as little as 20,000+ miles. Tiffin and Cummins should inspect all engines that have had documented harness/injector errors for potentially damaged/overheated crankshafts, as broken crankshafts have caused the engine failures.
NHTSA complaint 11533749DEF head failure. Shaw has failed to provide a working solution.
NHTSA complaint 11523556In 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. I am worry about the "Limp mode" if the sensor is not working causing a safety hazard. Either sensor needs to be more reliable or the enabling of the limp mode should be done under careful consideration giving enough time for the driver to get to safety.
