General Motors is recalling approximately 721,000 vehicles globally due to a potentially serious engine defect that could lead to a sudden loss of power, heightening the risk of a crash. The recall affects select 2021 through 2024 models equipped with 6.2-liter V8 gasoline engines, including Cadillac Escalade and Escalade ESV, Chevrolet Silverado 1500, Suburban, and Tahoe, as well as the GMC Sierra 1500, Yukon, and Yukon XL. Nearly 600,000 of the impacted vehicles are located in the United States.

According to the company, the problem involves defects in the crankshaft and connecting rod components that can cause severe engine damage or complete failure. GM has linked the defect to at least 12 crashes and 12 injuries in the U.S. alone. As part of the remedy, dealers will inspect affected engines and either repair or replace them if necessary. Vehicles that pass inspection will receive a higher viscosity oil along with an updated oil cap and oil filter replacement.

This large-scale recall follows a January investigation by the National Highway Traffic Safety Administration (NHTSA) into reports of engine failures in nearly 878,000 GM vehicles. GM itself launched a follow-up internal investigation and disclosed it had previously closed three inquiries into the same issue since 2022. The company has now acknowledged more than 28,000 field complaints and incidents tied to crankshaft, connecting rod, or engine-bearing malfunctions — with over 14,000 reports specifically involving propulsion loss.
