Service bulletin IB17X004

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

In order to improve the quality of the original equipment manufacturer (OEM) and service replacement engines and transmission assemblies, the Isuzu Quality Center (IQC) was implemented to assist dealers whenever an Isuzu diesel/gasoline engine or transmission assembly is thought to require replacement. The primary purpose of the IQC is to obtain faster and more accurate quality information on all failed engines and transmission assemblies. The collected information is used to improve the reliability of OEM and service replacement engine and transmission assemblies. Included in this program are all 1999-2018 OEM and 1999-2018 remanufactured assemblies replaced under normal warranty, goodwill, parts warranty, extended service contracts and over-the-counter assembly replacements as of November 1, 2009.
