This bulletin supersedes warranty bulletin WB08-X-001G. This bulletin is being
revised to announce prepaid freight and update policy information. Please discard
previous bulletin WB08-X-001G.
This bulletin provides instructions with regard to the Isuzu Commercial Vehicle (CV) Warranty
Parts Center on the topics of parts retention, parts preparation for shipping, and administration.
NOTE: Effective June 1, 2021 dealers/service centers must return parts requested by Isuzu
to the CV Warranty Parts Center using the prepaid shipping labels provided by Isuzu. See
the Freight Reimbursement section for details.
The CV Warranty Parts Center process is used to obtain parts replaced by Isuzu Dealerships and
Isuzu Engine Certified Service Centers (excluding Canada) to enable Isuzu to perform root cause
analysis of customer product concerns. The CV Warranty Parts Center issues part return
requests to the dealerships/service centers to obtain the desired parts. Dealers/service centers
must return the requested parts to the CV Warranty Parts Center within 20 days of notification of
the request. Failure to comply with the request may result in partial or complete chargeback of
the claim associated with the request. Chargebacks for non-returned parts are processed
automatically by the CV Warranty Parts Center computer systems. To ensure compliance with
these requirements and avoid a chargeback situation, it is highly recommended that an individual
(and a back-up person) be assigned the responsibility of processing these requests as quickly as
possible.
NOTE: Requested parts received after a chargeback has been initiated (late parts) will not stop
or reverse the chargeback process.

INFORMATION
Requests - “Part” or “Repair Order Only”
When a part (with repair order copy) or repair order ONLY is needed, the request will be
communicated through the Isuzu Communication System (ICS). The requests will be posted in
the “Warranty Parts Return Requests” section. Refer to the sample report provided.
The service manager, parts manager, and warranty administrator at your dealership will also
receive a one-time email for each warranty parts return request that Isuzu creates. Ensure that
these individual email addresses are correct by reviewing them in GoIsuzu.net. These emails are

a courtesy and in no way replace the dealer’s responsibility to check ICS for new Warranty Parts
Return Requests.
Part Preparation for Shipping
All parts related to a request should be returned together. The area of concern should be clearly
marked so that it can be easily identified. Try to ship each request in a separate box. If an
individual request requires several boxes because of size or other limitations, ensure each box is
marked with the claim number and grouped with the other boxes that are part of the claim. DO
NOT SEND MULITIPLE REQUESTS IN THE SAME BOX. Copies of the “request”, repair order
(legible copies of both sides of the hard copy including technician notes/comments) and an Isuzu
Warranty Parts tag must be attached to each part sent to the CV Warranty Parts Center. The
claim number pertaining to the requested part should be highlighted. Place the folded paperwork
in a plastic packing bag with the highlighted claim numbers facing out. The bag containing all
paperwork must be securely attached to the appropriate part. This process will assist in
processing and crediting the dealership/service center for returning the part in a timely manner.
When possible, the container from the new/replacement part should be used for the return of the
failed part. However, all previous shipping labels should be removed or covered prior to re-use.
(Leaving a prior shipping label exposed can cause errors in shipping.) Be sure to use ONLY boxes
without hazardous materials labeling to return NON hazmat parts. Parts containing or soaked by
fluids, such as oil or fuel, MUST be thoroughly drained, wiped clean and placed in an appropriate
packing container and securely packaged to prevent leakage or contamination. Transfer all caps
and plugs from the new part to the replaced part for shipping. Use only clean dry boxes to return
parts. Boxes that have absorbed oil or other fluids should not be used to return parts.
Be sure to package parts in a manner that will prevent them from being damaged during shipping.
Bubble wrap or other protective packing material may be needed. It is important that parts arrive
in the same condition they were in when they were removed from the vehicles.
Parts Retention and Requests
The Service Policy and Procedure Manual (SP&P) states all warranty parts are to be turned into
your dealership’s parts department by technicians for tagging, retention and/or return. This
includes all parts with core charge as well as all parts for repairs performed by a sublet shop.
Retain for inspection all warranty parts for a minimum of 30 days from the FINAL claim payment
notification or until an Isuzu representative authorizes their scrapping, whichever occurs first.
Parts (excluding parts with core charge) not requested within the 30-day retention period, or
scrapped per the authorization of an Isuzu representative, MUST BE DESTROYED AND
SCRAPPED BY THE DEALER/SERVICE CENTER. Parts with core charge not requested within
the 30-day retention period should be returned for core credit as outlined in the Dealer Parts
Policies and Procedures Manual. Under no circumstances are warranty parts to be installed on
any vehicle sold retail or as salvage, or used in any other application.
IMPORTANT: Do not return parts to the core consolidator until after the 30-day retention period
has expired.
Daily, or after the claim is paid, the dealer/service center should check the Warranty Parts Return
Request screen in ICS for “parts” or “repair order ONLY” requests. This screen will identify the
paid claims with open requests. From this screen the request details (packing list) can be viewed
and printed. A copy of this claim detail (packing list) must be returned with the requested parts.
Sample images are provided below. All CV Warranty Parts Return requests take priority over
returning cores to the Core Return Center. If the part return system did NOT request the part,
then per the Isuzu SP&P manual, parts with core charges should be returned to the appropriate
core return center, and parts without core charges should be scrapped locally.
IMPORTANT: Do NOT return parts to Isuzu that were not requested. Unsolicited and/or nonIsuzu parts returned to the Isuzu CV Warranty Parts Return Center will become the property of
Isuzu Commercial Truck of America and may be scrapped.

Requested parts should be shipped and post-marked no later than 20 days from the date
requested. The number of days the warranty parts request has been open is displayed on the far
right column of the “Warranty Parts Return Requests” section of ICS. Parts must be shipped
using the prepaid labels available from Isuzu in ICS. Other delivery methods will not be
reimbursed by Isuzu.
Parts Waiver Request
On those rare occasions when a requested part is not available for return, a Parts Waiver Request
Form must be completed and sent to your dealer’s DSPM immediately.
The Parts Waiver Request Form can be found on GoIsuzu.net in a “fillable” PDF format. To access
this form, perform the following:


Go to www.goisuzu.net and log in.
Click on the “MENU” button in the upper left hand corner of the GoIsuzu.net main page.
Click on “Service”.
Click on “Literature and Forms”.
Click on the “Warranty Parts Waiver Form” PDF icon.
Click on “Download” next to the PDF Icon above the Parts Waiver Request Form in order
to download the “fillable” PDF.

Complete the Parts Waiver Request Form, save it on your computer, and send it to your DSPM
as an email attachment. Your DSPM will then send it to the CV Warranty Parts Return Center.
Forms must be completed, signed by your DSPM or other authorized Isuzu representative and
received by the CV Warranty Parts Return Center within 20 days of the part requested date.
Waivers received after 21 days will not be considered.
Please note that not all explanations will prevent a chargeback.
Repair Order Only Requests
If a “Repair Order Only” request is received, return legible copies of the R.O., including technician
comments, directly to the requester using the mailing address provided on the CV Warranty Parts
Center request. DO NOT RETURN PARTS on this type of request. When returning “Repair
Order Only” requests, only use REGULAR 1 st Class Postal Service mail. Do not use Registered,
Certified or Insured mail of any type.
Core Reimbursement
Core credits for warranty engines and transmissions requested by the Isuzu Quality Center (IQC)
or Technical Assistance Line (TAL) will be processed automatically once the core has been
received. No action is required by the Dealership. Other core charges for parts requested by the
CV Warranty Parts Return Center may be claimed against the original warranty claim with an Add
Credit claim once the warranty parts request status is “Received”. When an engine or
transmission is collected by the IQC or TAL, upon receipt of the core, the core credit will be issued
automatically back to the dealer. Do NOT attempt to add core value for an engine or transmission
to a warranty claim.
Freight Reimbursement
We are pleased to announce prepaid shipping for warranty part return requests is now
available in ICS. This new function will allow dealers to more easily return any requested
part to the Isuzu CV Warranty parts center at no cost to the dealer. The system will generate
Federal Express prepaid labels for packages under 150 lbs. For freight over 150 lbs. and certain
oversized items, Yellow Roadway Corporation (YRC) freight prepaid labels are also available.
Follow the information provided in this bulletin to learn where to find and how to use the new
prepaid shipping function. Dealer MUST use this option when returning requested warranty parts
to Isuzu.

Dealers/service centers will not be reimbursed for freight. Isuzu provides prepaid shipping labels
for all warranty parts returns at no cost to the dealer. Make sure the follow the steps provided in
this bulletin to print out the prepaid shipping labels to return requested warranty parts to Isuzu.
Labor Hours
Dealers can submit their actual time used to process Warranty Parts Center (WPC) part return
requests, up to a maximum of .3 hour per claim. For "repair order only" requests, up to .2 hour
can be submitted. The time requested for reimbursement depends on the complexity of the
request as determined by the dealer. If other labor hours (OLH) are required, dealers must obtain
DSPM approval.
IMPORTANT: For all CV Warranty Parts center claims, be sure to attach a copy of the CV
Warranty Parts request and shipping invoice to the repair order.
Submit a “Regular” warranty claim using Labor Operation Z7200 for warranty part return
administrative time reimbursement. Enter labor hours into the “Labor Hours” field. Only this field
should be used for reimbursement. Any other entries may delay claim payment.
All related documentation, including a copy of the CV Warranty Parts Center return request, must
be retained for future reference in accordance with the Isuzu SP&P manual.

warranty part(s) that need to be returned to Isuzu.

the requested parts for the claim.
NOTE: A final version of the Packing List will need to be printed after the
shipping label has been generated. Only this final version will contain the

important shipping information that must be included with the parts being
returned.

4. Retrieve and properly package the parts, but do not seal the box(es) yet. If
multiple boxes are necessary to return a single request, make sure to note the
contents of each box. This detail will be needed when generating the shipping
label and final packing list.
5. Click on “Select Action” then click on “Generate Label”.

6. Follow the instructions to generate either a FedEx shipping label or a YRC
shipping label. Be sure to select the appropriate carrier based on the weight
and/or size of the part(s) being returned. Packages under 150lbs should be

shipped via FedEx while parts over 150lbs or oversized should be shipped via
YRC.

7. Print one shipping label for each box that will be shipped for that claim (shipping
labels can be reprinted as necessary after the initial print).

8. Click on the “Packing List” tab above the shipping label to generate the final
Packing List. Print one copy of the final Packing List for each box that will be
shipped for that claim.

NOTE: Each copy of the final Packing List must include the shipping
information at the bottom.

9. Place a copy of the final Packing List, which includes the box number (more than
one copy may be needed if there are multiple boxes for 1 request) into each box
being returned for that claim. Finish packaging the parts.
10. Properly affix shipping label(s) to the package(s) created in Step 4.
11. Schedule package pick up with the selected carrier. The carrier will deliver the
packages to the Isuzu Warranty Parts Center. The status for your return will
change from “Label Generated” to “In Transit”.
12. Monitor the status of your returned parts in the “Warranty Part Rtrn Req.” section
in ICS. (Refer to the “Index View of the WPR Request Screen” above.)
13. When the part is received by the shipping department and the WPC, the request
status will change to “Delivered”.
14. The delivered packaged will normally be processed by the WPC within 24 hours.
If all parts were returned as requested, the request status will change to
“Accepted”. (Refer to the “Index View of the WPR Request Screen” above for
