The supply constraint issues currently prevailing in the U.S. auto industry mean that GMC dealers are no longer able to order step lights for the 2021 GMC Sierra HD full-size pickup trucks fitted with the MultiPro tailgate, GM Authority has learned.
The MultiPro tailgate is also offered under the Multi-Flex name on the Sierra’s corporate cousin, the 2021 Chevy Silverado, and will be fitted as standard to all currently known variants of the GMC Hummer EV all-electric pickup, which will initially go on sale in Edition 1 form in the fall of 2021. It is offered as a $1,755 option on the base Sierra and is available as standard on all other trim levels.
The step lights, which have the RPO code 63G and are an LPO (dealer-installed) accessory, were priced at $200. It is unclear whether they will become available again for the remainder of the vehicle’s 2021 model year, or even in the early days of the 2022 GMC Sierra HD. The latter is expected to go on sale in the third quarter of 2021 with only minor changes, including new exterior colors and a slight revision of equipment and features within trim levels.
The same situation applies to the light-duty 2021 GMC Sierra 1500, which has similar availability of the MultiPro tailgate to the HD models, but can no longer be ordered with the step lights. It is at present impossible to say when the step lights will once more be available for that truck either.
Some customers will find this disappointing, but it is unlikely to have a serious effect on the popularity of the Sierra, whose U.S. sales in 2020 of 253,016 units were the third highest of any GM model behind the Silverado (594,094) and the Chevy Equinox crossover (270,994). The pickups were among the few GM vehicles to experience growth last year, despite a two-month delay in production caused by the COVID-19 pandemic.
Together, they outsold the Ford F-Series by 847,110 units to 787,422, though this was partly due to the fact that the Ford’s production was reduced as its 14th generation was introduced.
