INFORMATION
IMPORTANT: Effective April 15, 2015 – Dealers must now contact their DSPMs for the
IQC number and warranty approval after submitting their request online.
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 1999-2016 OEM and 1999-2016 remanufactured assemblies replaced
under normal warranty, goodwill policy, parts warranty, extended service contracts and over-the-counter
assembly replacements as of November 1, 2009.

IMPORTANT: Online submissions must be complete, including a dealer contact phone number or

authorization process.
Once the dealer has completed this process the IQC will review the submitted information. In some
cases additional information may be requested by the IQC to better understand the condition and nature
of the failure. Once all information is collected the IQC will provide the recommended repair method and
forward the information to the DSPM. The DSPM will call the contact person, review the failure,
diagnosis, warranty coverage and, if approved, issue a case number. It is important that this number be
added into the warranty claim. Claims without a case number will not be reimbursed.
Online access is available at www.isuzutruckservice.com. The IQC will be available for live assistance
Monday through Friday from 8am-5pm (EST). Contact the IQC at 1-866-309-8324 for US dealers (1-855486-5828 for Canadian dealers). If you have any questions, contact your DSPM.
