General Motors is voluntarily recalling a large batch of its most popular full-size trucks and SUVs due to a potential engine defect tied to the 6.2-litre V8 “L87” engine. The issue may cause catastrophic engine failure, prompting GM to also halt the sale of all affected models still in dealer inventory.

Vehicles Involved in the Recall
The problem affects select 2021 through 2024 model years of the following vehicles equipped with the 6.2L V8 engine:
- Cadillac Escalade
- Cadillac Escalade ESV
- Chevrolet Silverado 1500
- Chevrolet Tahoe

Approximately 721,000 vehicles globally are estimated to be affected, with 50,000 of those in Canada alone.
What’s the Issue? Manufacturing Defects Could Cause Engine Failure
GM’s bulletin to dealers outlines concerns about possible defects in the crankshaft or connecting rods. These internal engine components may have been improperly manufactured, leading to:
- Complete engine seizure
- Connecting rods breaking through the engine block
- Zero warning before failure, according to complaints
The U.S. National Highway Traffic Safety Administration (NHTSA) began an investigation earlier this year after receiving 39 complaints and multiple field reports.
Immediate Action: Sales Halted, Vehicles Inspected
General Motors has issued instructions for dealers to inspect all affected vehicles currently in inventory. Only those that pass inspection may be sold, and even then, they require several service updates:
- New higher-viscosity engine oil
- Updated oil filter
- Replacement oil filler cap
- Addendum to the owner’s manual
Any vehicle that fails inspection may require a complete engine replacement.
No Formal Recall Yet, But Precaution is Urged
As of now, neither NHTSA nor Transport Canada has issued a formal recall notice. However, GM has acknowledged the defect and is proactively addressing the issue at the dealership level.
If you own one of the listed vehicles, it’s wise to check your vehicle’s status using your 17-digit Vehicle Identification Number (VIN). Owners can do this on the recall pages of:

Looking Ahead: 2025 Models Get Updated Manufacturing
GM has reportedly updated its manufacturing tooling to address the root cause of the issue for 2025 model-year vehicles. These new models are not expected to be affected by the crankshaft or connecting rod defect.
What Should Owners Do Now?
If you drive a 2021–2024 GM truck or SUV with a 6.2L V8 engine, here’s what you should do:
- Check your VIN on the manufacturer’s recall page
- Contact your dealer for an inspection if your vehicle is affected
- Ensure your address is up to date with the automaker to receive official recall notices
- Monitor updates from NHTSA and Transport Canada as more information becomes available
Conclusion
While the recall has yet to be formally issued by government agencies, GM’s proactive measures suggest the risk of serious engine damage is real. Owners of affected vehicles should act promptly to avoid unexpected engine failure and costly repairs.
