General Motors is recalling nearly 600,000 vehicles equipped with a 6.2-liter V8 gasoline engine (RPO L87) after a GM investigation found that the connecting rod and/or crankshaft engine components in these vehicles may have manufacturing defects. GM determined that engine damage or failure could occur, causing the vehicles to lose propulsion.
The recall covers 2021-2024 models, including:

On January 16, 2025, GM opened a product investigation after the NHTSA notified them about alleged engine failures. Some warning signs drivers noticed included the check engine light turning on, unusual noises like banging or knocking, and performance issues like hesitation, high RPMs, irregular shifting, and reduced propulsion. Other vehicles didn’t start.
GM tore down affected engines and found rod-bearing damage from sediment on connecting rods and crankshaft-oil galleries. Investigators also found out-of-specification crankshaft dimensions and surface finish. All of these issues can cause or contribute to bearing damage. GM reported the findings back to the NHTSA and advised a recall for vehicles built between March 1, 2021 and May 31, 2024.

Dealers will inspect and either repair or replace engines in the recalled vehicles. Owners will be reimbursed by dealers for any repairs. Vehicles that pass the required diagnostic testing will be given a higher viscosity oil change, a new oil fill cap, an oil filter replacement, and an owner’s manual insert.
The owners of recalled models will begin to receive written notification by mail starting on June 9. However, the parts needed to fix the engine issues are not available at this time. GM is currently working with suppliers to get the needed parts as quickly as possible. Once they are available, dealers will receive a notification that repairs can begin.
In the meantime, dealers cannot sell, deliver, trade, or release to auction any vehicle that’s been recalled. That applies to new or used models. The vehicles that are affected can’t be used for shuttle vehicles, courtesy transportation, or test drives either. While they wait for parts and repairs, vehicle owners can also take a look at our article that explains what to do if you get a car recall.
