WASHINGTON, D.C.: General Motors is recalling more than 720,000 vehicles globally over a defect linked to its 6.2L V8 engines, the company said this week, citing a potential loss of engine power and increased crash risk.

The recall affects several of GM's most popular SUVs and pickup trucks from the 2021 through 2024 model years. Impacted vehicles include the Cadillac Escalade and Escalade ESV, Chevrolet Silverado 1500, Suburban, and Tahoe, as well as the GMC Sierra 1500, Yukon, and Yukon XL.

Of the total, nearly 600,000 vehicles are in the United States.

According to GM, the issue stems from possible manufacturing defects in the engine's crankshaft and connecting rod components. These flaws could lead to engine damage or outright failure. The automaker has linked the issue to 12 crashes and 12 injuries in the U.S.

As part of the recall, dealers will inspect the engines in affected vehicles. Those that pass inspection will receive a higher viscosity oil along with a new oil cap and replacement oil filter. Engines showing damage will be repaired or replaced.

The announcement follows a January investigation by the National Highway Traffic Safety Administration (NHTSA) into nearly 878,000 GM vehicles after receiving reports of V8 engine failures. GM subsequently launched its own internal probe.

Though GM had closed three earlier investigations into the issue between 2022 and 2023, it has now acknowledged a larger pattern. The company has recorded more than 28,000 field complaints or incidents potentially linked to engine failure caused by issues with the crankshaft, connecting rods, or engine bearings. Of those, over 14,000 included claims of propulsion loss.

The recall adds further scrutiny to GM's V8 engines at a time when safety regulators are intensifying oversight of legacy automakers. The company said it is working closely with NHTSA and will begin notifying affected owners soon.
