Rumors have been going around that a Gen 6 small block V8 may be on the way for the C8 Corvette.
Let’s hope such a replacement, if it does happen, is more reliable than the 6.2-liter L87 engines that have been recalled in certain 2021-2024 General Motors trucks and SUVs – and the subject of a class-action lawsuit filed Monday by a Seattle law firm.
The suit, filed in U.S. District Court for the Eastern District of Michigan by the Hagens Berman firm on behalf of specific plaintiffs from Washington and California, accuses GM of knowingly selling and leasing vehicles with defective and unsafe engines.
For 2025 vehicles, GM says it has corrected the manufacturing process blamed in the lawsuit for causing rod-bearing damage created by sediment on the connecting rods and in the crankshaft oil galleries in certain 2021-2024 vehicles, leading to a loss of propulsion that could become a safety hazard and sometimes requires the installation of a new engine.
The suit also alleges that the defect lowers the value of these vehicles, causing financial harm to the plaintiffs. “Simply replacing the defective engine with the same type of engine does not address the Bearing Defect and leaves consumers subject to the same undisclosed safety risk,” the suit claims.
After a detailed analysis of field data and teardown inspections, GM believes the defects are limited to a build period between March 1, 2021, and May 31, 2024, and that new manufacturing processes have eliminated the problem for 2025 vehicles.
Following a series of investigations, engine replacements, and other lawsuits regarding consistent problems In response to the issue, GM has issued safety recall N252494001, which instructs dealers to inspect the vehicles with those that pass inspection to be provided a higher viscosity oil, which will also require a new oil fill cap, an oil filter replacement, and an owner’s manual insert.
The 2021-2024 Chevy Silverado 1500, GMC Sierra 1500, Chevy Tahoe/Suburban, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV are listed in the suit. Affected owners will be notified by GM with further instructions.
