2024 GMC Sierra

The 2024 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 are set to receive a major refresh for 2024, including new front and rear end designs, a new interior, along with potential powertrain updates.

It’s worth noting that this refresh was originally scheduled for the 2023 model year, however, the product cycle is behind due to complications brought on by COVID-19 and a shortage of superconductor chips. Additionally, the fourth-generation Sierra HD pickups are currently performing extremely well in the market place.
