General Motors (GM) is recalling nearly 600,000 trucks and SUVs due to serious defects found in its 6.2-liter V-8 engines. Problems with the connecting rods or crankshaft can damage the engine or cause it to fail completely. The recall includes 2021-2024 models of GM’s popular models, including the Cadillac Escalade, Chevrolet Silverado, Tahoe, Suburban, GMC Sierra, Yukon, and Yukon XL.
According to the recall report, drivers can identify problems early on by symptoms such as unusual engine noises, a check engine light, high RPM, shifting problems, or reduced power. GM’s investigation revealed that these engine problems were most commonly found in vehicles built between March 1, 2021, and May 31, 2024. The company attributed the recall to quality lapses in the manufacturing process and crankshaft dimensional errors.
