From owner reports, verbatim
This vehicle like many thousands has a DEF system that uses Diesel Exhaust Fluid in addition to Diesel fuel. This POLLUTION CONTROL SCHEME, Installed by both Freight Liner and Cummins diesel, when it fails, it orverides all engine speed controls and only allows the vehicle to drive at 5 mph. THIS IS UNSAFE, DARK, HEAVILY TRAVELED ROADS WITH LARGE SEMI TRACTOR TRAILERS, BUS'S, PASSENGER CARS AND TRUCKS RUNNING AT 70- TO 90 MPH coming up on a 5 MPH vehicle presents a SERIOUS SAFETY ISSUE FOR HUMAN BEINGS, CHILDREN, AND ALL OTHERS AND IS OUTRAGEOUS THAT IT IS ALLOWED AND IT IS FORCED ONTO ALL DIESEL POWERED MOTOR HOMES AS WELL AS MILLIONS OF OTHER VEHICLES. DO WE HAVE ANY REAL SAFETY PEOPLE WHO ARE BEING PAID TO MAKE OUR VEHICLES AND ROADS SAFE, THAT GIVE A DAMN. THIS SPEED CONTROL LIMIT IS A TERRIBLE WAY TO ENFORCE A POLLUTION CONTROLS SYSTEM ON THE AMERICAN PEOPLE. WILL ANYONE HAVE THE BACKBONE TO CORRECT THIS UNSAFE, DUMB, SYSTEM, ANYONE. I WAS LEFT STRANDED ON A HIGHWAY YESTERDAY, Nov. 1, 2022 NEAR VERO BEACH, FLORIDA IN MY DIESEL PUSHER MOTOR HOME. I AM MAD AS HELL, AND ALL OF YOU SHOULD FIX THIS INSANE PROBLEM.

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.
