General Motors (GM) recently issued a recall for certain 2021-2024 Cadillac, Chevrolet, and GMC vehicles.

The recall, estimating 597,571 units, calls attention to GM vehicles equipped with a 6.2L V8 gas engine. The connecting rod and/or crankshaft engine components may have manufacturing defects that can lead to engine damage and engine failure.

Specific vehicle impacts include:

• 2021-2024 Cadillac Escalade: 79,747

• 2021-2024 Cadillac Escalade ESV: 46,280

• 2021-2024 Chevrolet Silverado 1500: 107,244

• 2021-2024 GMC Yukon XL: 60,933

Reason for the Recall

In January 2025, GM opened a product investigation following notification from the National Highway Traffic Safety Administration (NHTSA) of its investigation into alleged engine failures in GM vehicles equipped with the L87 V8 engine.

GM’s updated field data analysis identified a build period from March 1, 2021, to May 31, 2024, with an increased rate of potentially related engine failure claims. Supplier manufacturing and quality issues were identified at intermittent periods within the suspect build period, including rod-bearing damage from sediment on connecting rods and crankshaft-oil galleries and out-of-specify crankshaft dimensions and surface finish.

If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash and potential engine damage. GM’s investigation identified 28,102 field complaints or incidents in the US potentially related to the failure of the L87 engine due to crankshaft, connecting rod, or engine bearing failure, of which 14,332 involved allegations of loss of propulsion.

Drivers may be alerted to the condition before failure from:

• Knocking, banging, or other unusual engine noises,

• Illumination of the check engine light

• Engine performance issues, including hesitation, high RPMs, abnormal shifting, reduced propulsion, or a no-start condition   

Remedy and Vehicle Inspection

Dealers will inspect the engine and, as necessary, repair or replace the engine. For vehicles that pass inspection, dealers will add higher viscosity oil, install a new oil fill cap, replace the oil filter, and update the owner’s manual.

Repairs will be performed free of charge. Owner notification letters are expected to be mailed on June 9, 2025.
