If your GM truck or SUV has the 6.2L V8 and the engine failed, stalled, or got a recall notice, you have a choice to make. You can wait on the GM V8 engine lawsuit, or you can pursue your own lemon law buyback, which is often faster. This guide explains the defect, who is affected, and how to decide.
Key Takeaways
- The GM V8 engine lawsuit centers on the 6.2L V8, engine code L87, which GM recalled over connecting rod and crankshaft defects that can cause sudden engine failure. (Source: NHTSA Recall 25V-274)
- NHTSA recall 25V-274 covers 597,571 U.S. trucks and SUVs from the 2021 to 2024 model years. (Source: NHTSA)
- A class action seeks one shared remedy for a large group and can take years. A lemon law buyback is your own claim and often resolves in months.
- If your engine already failed or the recall fix did not hold, that repair history can support a buyback. Keep every record.
What is wrong with the GM 6.2L L87 V8?
The problem is inside the engine. GM’s 6.2L V8, known by the code L87, was built with connecting rod and crankshaft defects that can lead to engine damage and complete engine failure. When the engine fails while you are driving, the truck can lose power, which raises the risk of a crash. That safety risk is why GM issued a recall. (Source: NHTSA Safety Recall 25V-274, nhtsa.gov)
In plain terms, debris and out-of-spec parts can damage the bearings that keep the engine running. Once that happens, oil pressure drops and the engine can seize. GM’s own filing lists the warning signs owners may notice first: knocking or banging noises, a check engine light, hesitation, high RPMs, abnormal shifting, reduced power, or a no-start.

A consolidated federal class action claims GM knew about the defect and that its repair does not fully resolve it. Those are allegations that a court has not decided, and we take no position on them here. What is on the public record, and what matters for your options, is the recall itself and your own repair history.
Which trucks and SUVs are affected?
The recall covers the 6.2L V8 (L87) in these 2021 to 2024 models. (Source: NHTSA 25V-274)
- Chevrolet: Silverado 1500, Tahoe, Suburban
- GMC: Sierra 1500, Yukon, Yukon XL
- Cadillac: Escalade, Escalade ESV
Vehicles with other engines, or built outside the recall’s March 2021 to May 2024 production window, are not part of this recall.
Owners of newer or older GM trucks and SUVs with the 6.2L V8 have also reported engine failures, and federal regulators are reviewing vehicles beyond the original recall window. The only reliable way to know whether your exact truck is covered is to check your VIN. Find your 17-character VIN on the lower left of your windshield or your registration, and enter it at the official NHTSA recall lookup.
Class action lawsuit vs. your own lemon law claim
Here is the decision that matters most. The GM V8 engine lawsuit and a lemon law claim solve different problems, and you do not always have to pick just one.
A class action pools many owners into one case that seeks a shared remedy. You usually take part as a group member, you share in whatever the group recovers, and you wait on the court, which can take years. You risk little, but you control little, and the group remedy may be smaller than what your individual vehicle is worth.
A General Motors lemon law claim is your own case. It is built on your repair orders, under your state lemon law and the federal Magnuson-Moss Warranty Act. If your vehicle qualifies, a buyback can return your purchase price, loan payoff, taxes, and fees, and it often resolves far sooner than a class action.
Many owners choose to pursue an individual lemon law claim. Whether you can do that and also remain part of a class action depends on the case terms and your state, so it is worth asking before you decide.

What to do if your engine failed or stalled
If your 6.2L V8 already failed, stalled, or went in for the recall, your next steps protect both options. Here is what we tell GM owners to do:
- Keep every document. Save the recall notice, every repair order, and any record of a replaced engine, an oil change under the recall, or a loaner. This paper trail is the backbone of a lemon law claim.
- Go back for every repeat problem. If the engine was repaired and the trouble returns, bring it back and ask for a written repair order each time. A recall repair counts as a repair attempt, and a repeat failure after that fix is powerful evidence.
- Track your days out of service. Note every day the truck sat at the dealer. Cumulative time out of service matters under many state lemon laws.
- Check your VIN. Confirm the recall on the NHTSA lookup so you know exactly what GM has acknowledged.
NHTSA has also opened a review into reports of engines that failed even after the recall repair was performed. You can see the current recall and investigation status for GM’s 6.2L V8 on the NHTSA site.
How much a GM lemon law buyback is worth
A GM lemon law buyback is designed to make you whole, not to hand you a guess. When a vehicle qualifies, a buyback can include your full purchase price, your remaining loan balance paid to your lender, taxes, title, registration, and documented out-of-pocket costs like rentals and towing. In most cases the manufacturer pays your attorney’s fees separately, so your recovery stays with you.
We do not publish a dollar figure, because the honest answer is that it depends on your vehicle, your payments, and your state. Some states, including California under the Song-Beverly Act, allow additional penalties when a manufacturer’s conduct is found to be willful, but every case is different and results vary.
