According to GM Authority, GMC Sierra HD pickup prices have just increased and are set to rise once again. 

 GMC and Buick increased the cost of several models in their portfolios by anywhere from $975 to $1,675 by making the OnStar service standard instead of an option. 

The largest price hike goes to the big boy Sierra HD, which now costs $1,500 for three years of OnStar service 

The MSRPs for the full 2023 Sierra HD lineup will also go up by $1,000, according to GMA.

However, after running the calculations and accounting for OnStar, we believe the increase might really range from roughly $800 to at least $1,100. 

According to the GMC configurator, the pricing of a base Regular Cab Sierra HD Pro 2WD will be $44,770 in the next year.

GMC could be adding $1,000 to the MSRP and $100 to destination even though GMA didn't break out the destination fee for the next year.

According to the configurator, the base price for the 2022 Sierra 3500 is $43,195. According to GMA, same model will earn $45,970 the next year, a $2,775 increase.

the 2500 HD SLE, so we must deduct the $1,675 to get back to the $1,100 difference that seems to be the crux of the whole thing.

If everything goes according to plan, the 2023 Sierra HD will be replaced by a drastically updated 2024 model with interior improvements 

The interior changes can be seen in spy photos, including a rearranged instrument panel with a potential 13.4-inch infotainment touchscreen.
