Information
Note: This bulletin pertains only to vehicles that had an
original Genuine GM tonneau cover installed.
For OEM Tonneau cover replacement under warranty,
GM P/N’s are being discontinued (see chart below). As
these GM part numbers sell down, GM will be replacing
these part numbers with IBP* part numbers, both for
new sales and for warranty replacements. For a
cross-reference of these parts lists, see the Parts
Information table below. However, using these part
numbers will cause errors in claim submissions to
GWM. Please reference instructions below for claim
support.
For Genuine GM Accessory Part (LPO*) Originally
Installed during PDI
For vehicles with RPO 63B/VOZ on the build, please
submit your warranty claim using labor code 0522230
and the corresponding IBP part # (see below). This will
result in an “51 Service Agent is not allowed to submit
part product line 32” error, which will need to be
authorized by the Warranty Support Center.
For Genuine GM Accessory Part Purchased as an
ACO* (over the counter)
For vehicles with add on option #92 or #93 in the
“Added Option Codes” in IVH – verify that the original
install was the Genuine GM part numbers (see below).
If so, submit claim the same way as an LPO.
If not listed as LPO or as an Added Option in IVH,
dealer will have to review install RO or receive receipt
information from customer.
If original install was IBP part
Contact the IBP supplier for warranty coverage.
Dealership labor for processing warranty repairs
approved by the accessory manufacturer may be
claimed through GWM. Refer to bulletin # 11–00–
89–002.
*LPO – Limited Production Option, Ordered with the
vehicle, not an over the counter sale.
*ACO – Accessory Catalog Offering, Over the
counter sale.
*IBP – Integrated Business Partner
