Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.
NHTSA #25E-004 (Cummins)

CSA-043 FCCC Chassis with Cummins L9 Engine Low Pressure Fuel Hose Tiffin received from Daimler Campaign # F1016; Cummins Campaign # C7111. Cummins Inc. has decided that a defect which relates to motor vehicle safety exists in certain Cummins L9 engines manufactured between 8/4/23 and 12/21/23. Due to a manufacturing error on the low-pressure fuel hose end crimp fitting, the remote fuel filter hoses installed on the subject engines can become separated from the fuel fitting resulting in fuel leaks and lack of fuel supply to the engine. A fuel hose that becomes disconnected will result in as engine stall increasing the risk of a crash. A fuel leak in the presence of an ignition source may increase the risk of fire. Cummins has released a field Safety Campaign C7111 to correct this condition by replacing the two subject fuel hoses with hoses having improved connector crimps. Repair parts are currently available at Cummin Distributors and authorized Warranty Dealers. Ther repair will be completed free of charge and most applications will require approximately 1 hour to complete. Until the campaign is completed, Cummins advises customer to periodically check the remote fuel filter hoses for signs of leaking, and immediately seek repairs if leaks are identified.
