GM Builds Pickups Without Certain Modules Due To Global Chip Shortage, Hurting Fuel Economy

General Motors said on Monday that due to the global semiconductor chip shortage the U.S. automaker is building certain 2021 light-duty full-size pickup trucks without a fuel management module, hurting those vehicles' fuel economy performance. From a report: The lack of the active fuel management/dynamic fuel management module means affected models, equipped with the 5.3-liter EcoTec3 V8 engine with both six-speed and eight-speed automatic transmission, will have lower fuel economy by one mile per gallon, spokeswoman Michelle Malcho said. Malcho emphasized all trucks are still being built, something GM has repeatedly stressed it would try to protect as pickups are among GM's most profitable models. She declined to say the volume of vehicles affected. "By taking this measure, we are better able to meet the strong customer and dealer demand for our full-size trucks as the industry continues to rebound and strengthen," Malcho wrote in an email. The change runs through the 2021 model year, which typically ends in late summer or early fall, she said.
