Manufacturer summary

Original wording in English

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.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
