General Motors is aware of an issue with the Electronic Parts Catalog (EPC) for bulletin N212354524. The part number for the VIN may not be visible due to the vehicle configuration for rear heated seats. A correction will be implemented in the EPC on August 10, 2022. However, in the meantime, dealers can uncheck the box for the VIN filter (at the top of the screen/page) in the EPC. This will allow the part number to be visible for ordering.
