General Motors has released a new service update affecting select Chevy and GMC vehicles, including the Chevy Suburban, GMC Sierra 1500, Sierra HD, and Yukon. Affected units were built without the graphics processor required for proper operation of the digital instrument cluster. To note, only seven units are affected by this service update.
The service update is tagged with service update number N232415790, and was released in January of the 2024 calendar year. The service update affects only seven Chevy and GMC trucks, the majority of which are located in the U.S., while one is located in Kuwait. Vehicles affected by this service update include:
Affected units are equipped with a digital multi-color full cluster display unit (RPO code UDV) that was produced without the provisioning for the graphics processor. In order to fix this issue, dealers are instructed to replace the instrument cluster with a functioning unit.
The exact reason why these units were built with digital display that did not include a graphics processor remains unclear.
Although likely unrelated, GM (and the broader automotive industry) faced a worldwide shortage of microchips between the 2021 and 2023 calendar years. The shortage resulted in a massive cut to production across the industry and billions of dollars lost. To address this issue, GM implemented what was known as a build-shy production strategy wherein vehicles were built without certain features in order to keep production lines moving, with the intent of retrofitting the missing features once additional microchips were sourced. Looking ahead, GM plans to produce its own microchips by the 2025 calendar year in order to circumvent possible future shortages.
