Service bulletin CB23-J-002
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
SPECIAL POLICY ADJUSTMENT: In some 2018-2021MY Isuzu F-series vehicles equipped with 5.2L (4HK1) diesel engines, the diesel particulate filter (DPF) fuel injector may fail, setting Diagnostic Trouble Code (DTC) P0420 in the Engine Control Module (ECM). If this occurs, the Check Engine Malfunction Indicator Lamp (MIL) will illuminate. This Special Policy covers the condition described above for a period of ten (10) years from the date the vehicle was originally placed in service, regardless of ownership, or 150,000 miles (241,000km), whichever occurs first. Diagnosis and repair of conditions other than the condition described above are not covered under this Special Policy.
