Potential Consequences:
RV WENT INTO 5MPH DERATE DUE TO DEF HEADER MALFUNCTION. I WAS VERY LUCKY TO BE IN AN RV PARK, HOWEVER THERE IS NO WAY TO REPLACE THE DEF HEADER WITHOUT RAISING THE RV (DUE TO THE LOCATION OF THE TANK), SO IT COULDN'T BE REPLACED THERE. I HAD AN APPOINTMENT TO REPLACE THE DEF HEADER AT FREIGHTLINER OF HOUSTON, DUE TO THE WARNING LIGHTS. HOWEVER WHEN I STARTED TO DRIVE THERE FOR THE APPOINTMENT, I FOUND THE RV WOULD NOT GO OVER 5MPH. SINCE THE DEALER WAS 60 MILES AWAY (AND IT WAS THE NEAREST ONE), THERE WAS NO WAY I COULD MAKE IT.

Potential Consequences:
I OWN A 2017 NEWMAR DUTCH STAR MOTOR HOME ON A FREIGHTLINER CHASSIS. THE DIESEL EXHAUST FLUID (DEF) SENSOR (DEF HEAD) HAS FAILED TWICE. THE FIRST FAILED AT 14,795 MILES AND WAS REPLACED ON 9/24/18. THAT HEAD LASTED ANOTHER 15,000 MILES AND FAILED AT 31,218 AND WAS REPLACED ON 11/25/2020. EACH HEAD LASTED ABOUT 15,000 MILES OR 2 YEARS. THE PART IS MADE BY SHAW DEVELOPMENT WHICH HAS NOT ANSWERED REPEATED ATTEMPTS FOR INFORMATION. AS PART OF THE EMISSIONS SYSTEM, FREIGHTLINER HAS REPLACED BOTH HEADS UNDER THE 5 YEAR FEDERALLY MANDATED WARRANTY ON EMISSION SYSTEMS. CUMMINS (WHICH MAKES THE ENGINE) ALSO IS INVOLVED IN EMISSIONS. THE THREE SEEM TO PASS THE BUCK FROM ONE TO THE OTHER LEAVING THE CONSUMER TO DEAL WITH THE SAFETY ISSUE OF DERATING AND COST AFTER THE WARRANTY. WHEN DEF SENSORS FAIL, THE ENGINE CAN GO INTO DERATE WHICH IS 5 MPH. THIS PROBLEM IS LEAVING MANY LARGE DIESEL ENGINE OWNED VEHICLES STRANDED, FROM MOTORHOMES TO LARGE OVER THE ROAD TRUCKS. I BELIEVE THEY ARE NOW ON GENERATION 6 DEF HEAD, AND FAILURES CONTINUE TO BE COMMON. SHAW DEVELOPMENT REFUSES TO TAKE CALLS OR EMAILS REQUESTING INFORMATION REGARDING THIS PROBLEM. THERE ARE NUMEROUS ONLINE POSTS OF SIMILAR ISSUES AND THOSE INVOLVED IN THE REPAIR BUSINESS TELL ME THIS IS A VERY COMMON FAILURE. MY UNDERSTANDING IS THAT DEF SENSORS MEASURE DEF CONCENTRATION PER REGULATIONS PASSED BY THE EPA IN 2016. THE PROBLEM IS THAT SHAW DEVELOPMENT HAS NOT DEVELOPED AN ADEQUATE TOOL TO FOLLOW THIS REGULATION WHICH IS CAUSING SAFETY ISSUES AND EXPENSE TO CONSUMERS.

Defect Description:
ENGINE
Potential Consequences:
WE HAVE HAD TWO DIESEL EXHAUST FLUID (DEF) HEAD FAILURES THAT HAVE REQUIRED REPLACEMENT OF THE DEF HEAD UNIT. THE FIRST SITUATION RESULTED IN A DERATING OF THE ENGINE, LIMITING OUR SPEED TO 4 OR 5 MPH WHILE ON THE INTERSTATE. THE VEHICLE HAD TO BE TOWED 200 MILES TO A SERVICE CENTER, THEN IT TOOK A WEEK TO OBTAIN REPLACEMENT PARTS. THE SECOND SITUATION HAPPENED WITHIN 5 MILES OF A SERVICE CENTER AND WE WERE FORTUNATE ENOUGH TO BE ABLE TO MAKE IT TO THE SERVICE CENTER. HOWEVER, WE ARE SEEING HUNDREDS OF SIMILAR SITUATIONS BEING POSTED TO RV FORUMS ON VARIOUS SOCIAL NETWORKS. A RECALL NEEDS TO BE MADE FOR ALL CUMMINS ENGINES THAT HAVE DEF SYSTEMS. AS PART OF THE SOLUTION, THE DESIGNS NEED TO BE CHANGED SO THAT THE ENGINES CAN CONTINUE TO RUN WITH THE DEF ERROR CODE RATHER THAN SENDING THE ENGINE INTO A DERATE SITUATION AS THIS PRESENTS A SEVERE HAZARD TO OCCUPANTS IN THE VEHICLE, AS WELL AS OTHER TRAFFIC ON THE ROAD. RV BUILT ON A PREVOST CHASSIS ALLOW NORMAL OPERATION OF THE ENGINE AND RV SPEED EVEN WITH THE DEF ERROR CODES.
