Two 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.

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. 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.

Manufacturer communications
A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.
EXTERIOR LIGHTING
Stopped using the lights we had been using due to expense. Replaced with these, but these new lights have to be wired in instead of just clicking in. These are the instructions to wire in.
EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL
This was a letter to our dealers we sent out when we first heard of the Kidde fire extinguisher recall, even though it was still unofficial. We knew our coaches on the dealers' lots contained Kidde and could not be sold unreplaced.
EQUIPMENT ADAPTIVE/MOBILITY
Possibility that a wire on the electic compressor that is part of the air leveling system may not be properly connected, thus impacting leveling.
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
Compare model years
Complaint and recall counts across every year of this model
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
