General Motors has confirmed it is axing one feature from its popular SUVs and trucks. The removal isn’t by choice, but rather a reality due to a global semiconductor shortage.
GM Authority confirmed the change, which impacts 2021 Chevrolet Tahoe and Suburban, GMC Yukon, Yukon XL, Cadillac Escalade and Escalade ESV. Specifically, models equipped with a V-8 engine and 10-speed automatic will have start stop eliminated. Certain higher-end Chevrolet Silverados and GMC Sierra are also impacted.
Start stop technology is found on many new vehicles. The feature is designed to increase fuel economy by shutting off the engine during stops. Given its removal does negatively impact fuel economy, GM is offering customers of these vehicles a $50 credit on the window sticker to accommodate. GM has not disclosed if it expects a change in the EPA fuel economy ratings due to the removal of start stop.
In a note to dealerships GM reassured its supply chain is making progress in mitigating the impact of the semiconductor shortage. In recent months GM–like most automakers–has shuttered many assembly plants for months due to a lack of parts that contain semiconductor components. GM’s strategy has been to channel its finite semiconductor parts supply to keep its high-margin truck and SUV plants humming.
