General Motors (GM) has issued a significant recall affecting nearly 600,000 Cadillac, Chevrolet, and GMC SUVs and pickup trucks across the United States. This recall concerns a potentially serious engine defect involving the connecting rod and crankshaft components in certain V8 engines. If left unaddressed, the issue may lead to complete engine failure, increasing the risk of a crash. Owners are urged to act quickly to avoid dangerous breakdowns, especially while driving.
The issue has already triggered thousands of consumer complaints and is currently under investigation by U.S. safety regulators. If you drive one of the affected models, this recall could impact you directly.
What Is the Problem?
GM has identified manufacturing defects in the connecting rod and/or crankshaft engine components in certain 6.2-liter V8 engines. These defects can lead to severe engine damage and even total engine failure, especially while the vehicle is in use. This presents a heightened risk of collisions due to sudden loss of propulsion or control.
Some of the warning signs drivers may experience before engine failure include:
- Knocking or banging engine noises
- A lit “check engine” light
- Unusually high RPMs
- Reduced propulsion
- Delayed or failed engine starts
- Jerky or unusual shifting
GM has also reported at least 12 crashes, 12 injuries, and 42 fires related to this defect—though not all were confirmed to be directly linked to the engine issue.
What Vehicles Are Affected?
The recall covers 597,630 vehicles with 6.2L V8 engines from model years 2021 to 2024. Affected vehicles include:
Cadillac
– Escalade
– Escalade ESV
Chevrolet
– Silverado 1500
– Suburban
– Tahoe
GMC
– Sierra 1500
– Yukon
– Yukon XL
Owners can check their VIN on the NHTSA recall website to confirm if their vehicle is impacted.
What Is GM Doing to Fix It?
GM is instructing its dealers to inspect the engine of affected vehicles and repair or replace it as necessary—free of charge.
If the engine passes inspection, the dealership will:
- Add high-viscosity oil
- Replace the oil filter
- Install a new oil fill cap
- Update the vehicle’s owner’s manual
GM has committed to ensuring sufficient parts availability and technician readiness before the fix rollout.
