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.

Judging from the “fix”, meaning, 0-40 oil and a new cap, that the problem has to do with serious bearing tolerance issues. One that makes me wonder if the 0-40 fix is a fix, or a band-aid. Given time, the oil masks the real problem and in 10+ years, a bunch of these engine blow up. Lovely.
I hope this lawsuit actually forces GM to genuinely FIX the problem.

“GM believes the defects are limited to a build period between March 1, 2021, and May 31, 2024″…
Take x number of said powerplants assembled per day, multiplied by y number of workdays in the aforementioned timeframe, and you have a significant pickle to deal with!
Bummer.
Yes I have asked for replacement of a new vehicle my engine went out at 38,000 miles and almost caused me to be in a bad accident. Then they replaced my engine and I had a second default that almost caused me in a accudent. I am a salesman and if I would have been on major interstate I would have been killed. It left me and my daughter on a stranded road late at night and had to call a friend to tow my vehicle which we waited 3 hours. I called dealership and they did not want to pay for the problem after they told me if I had any other problems that they would give me around 20,000 fir a new vehicle. I contacted gm and they only offered me 2500. Plus this has made my car lose a ton of value.
I was one who bought a 2024 Chevy Silverado. Was told I had a recall. Took it in and was to go through an inspection. Left it there to get an inspection two weeks later finally had an inspection, failed. Was told I was to get a new engine. Today I get a phone call stating GM inspected my vehicle and because I have low miles on it with it being new and all that there’s no problem with my vehicle they’re going to do the oil and the oil cap And when it’s ready to come and get it. My fear is to drive that vehicle and have an accident because of the nun remedied issues with simple Band-Aid of an oil change.
