GM confirmed this week the four-way power lumbar support system in both the High Country and Premier trim levels of these full-size SUVs will be dropped for a two-way system as a result of the ongoing global microchip shortage. This change will affect the driver’s and front passenger’s seats only, as these are the only two seats in the vehicles that come equipped with power lumbar adjustment.
To be clear, only the High Country and Premier trim levels are offered with four-way power lumbar adjustment, so only these trim levels will be impacted by the change. The two-way power lumbar seat adjustment is already standard in the LS, LT, RST and Z71 trim levels.
This will also be a temporary change, however it will be in effect until further notice. Due to the ongoing nature of the global chip shortage, GM did not provide an estimate as to when this change will be lifted.
This change will also affect the power-adjustable front seats in 2022 Chevy Tahoe and Suburban Premier and High Country. Going forward and for a temporary time, the Premium and High Country variants of the SUVs will get 10-way power-adjustable front seats instead of the standard 12-way power seats.
Customers affected by these changes will receive a $50 credit from GM upon purchase.
GM has managed to mitigate the impact of the chip shortage on some of its products by removing certain electronic features from them. For example, the automaker previously removed Active Fuel Management and Dynamic Fuel Management from certain examples of the Chevy Silverado 1500 and GMC Sierra 1500, as well as Automatic Stop-Start and HD Radio. Some GM models have also had the optional wireless charging pad removed completely or introduced limited availability for the charging pad.
This strategy has enabled GM to keep production of its most profitable vehicles up and running amid the chip shortage, even if it doesn’t have all the chips it needs. The automaker has also implemented a strategy called “build shy” amid the supply chain crisis, which entails producing partially finished vehicles, storing them nearby production plants and then bringing them back into the plant for final assembly once it receives more chips.
“GM continues to leverage every available semiconductor to build and ship our most popular and in-demand products, including full-size trucks and SUVs for our customers,” the automaker said in a statement previously. “We continue to work closely with our supply base to find solutions for our suppliers’ semiconductor requirements and to mitigate impacts on GM.”
The 2022 Chevy Tahoe and 2022 Chevy Suburban are both produced at the GM Arlington Assembly plant in Texas.
