The recall follows an escalating number of lawsuits, investigations, and engine replacements tied to these powertrains.
This issue affects key GM models under the Chevrolet, GMC, and Cadillac brands, with nearly 50,000 vehicles recalled in Canada alone. The U.S. has already seen more than 597,000 similar models recalled for the same issue.

The Cause: Faulty Engine Components Could Lead to Sudden Failure
What Went Wrong
GM has traced the problem to manufacturing defects in engine components—specifically the connecting rods and crankshafts. These flawed parts can lead to:
- Loss of propulsion
- Engine damage
- Total engine failure
All of these outcomes significantly increase the risk of a crash, especially at highway speeds.
Affected Engine: The 6.2L V8 L87
This high-performance engine is designed for power and towing capabilities. However, the defects have made it a point of concern for both GM and vehicle owners.
The Fix: Inspections, Oil Changes, and Potential Engine Replacements
GM has outlined a multi-step process to address the issue:
- Inspection: Dealerships will inspect the engine for manufacturing defects.
- Oil Change: If no issues are found, the vehicle will receive an oil and filter change using 0W-40 Mobil 1 Supercar oil, instead of the previously recommended 0W-20.
- Cap Replacement: The oil fill cap will be updated to reflect the new oil specification.
- Repair or Replacement: If any defect is found, the engine will be repaired or replaced at no cost to the owner.
