2023 GMC Sierra

The 2023 GMC Sierra is expected to bring small rolling changes to the Light-Duty Sierra 1500 model following the major refresh for the 2022 model year.

Meanwhile, the Heavy-Duty Sierra 2500HD and Sierra 3500HD models were initially set to receive a major refresh for 2023 – including new front and rear end designs, a new interior, along with potential powertrain updates – however, the product cycle is now behind by a model year due to complications brought on by COVID-19 and a shortage of superconductor chips. Additionally, the current HDs are performing extremely well in the market place. As such, the HD models will also see small rolling changes for the 2023 model year.
