A consolidated federal class action over General Motors’ 6.2-liter L87 V8 engine is still working its way through court in Michigan, more than 300,000 miles and several model years removed from a different GM engine case that already reached a $150 million settlement. The two cases involve different engines and different owners, but together they show GM’s small-block V8 lineup has spent much of 2026 under sustained legal pressure over oil consumption and premature failure.

The active L87 case, Rittereiser et al. v. General Motors, LLC, is pending in the U.S. District Court for the Eastern District of Michigan, Southern Division, under case number 4:25-cv-11481-SDK-KGA, according to Hagens Berman’s case page, the law firm serving as interim co-lead counsel. A 389-page consolidated complaint combining multiple pending suits was filed on February 26, 2026, covering more than 877,000 vehicles.

Affected vehicles include 2019-2024 Chevrolet Silverado 1500 and GMC Sierra 1500 pickups, and 2021-2024 Cadillac Escalade, Chevrolet Suburban and Tahoe, and GMC Yukon and Yukon XL SUVs, all built with the L87. Plaintiffs allege the engine’s crankshaft bearings are prone to losing lubrication, which can breach the engine block or cause the engine to seize entirely — sometimes with as little as 1,200 miles on the odometer, and often at highway speed, per Hagens Berman’s filing summary.

Key Points

• L87 6.2L V8 class action covers over 877,000 Silverado, Sierra, Escalade, Suburban, Tahoe, Yukon and Yukon XL vehicles from model years 2019-2024.
• The consolidated complaint, filed February 26, 2026, argues GM’s recall remedy is inadequate and that GM has roughly 30,000 owner incident reports on file.
• A separate GM engine case — over the older 5.3-liter LC9 V8 in 2011-2014 trucks — reached final approval on a $150 million settlement in October 2025.

GM’s existing recall remedy for L87 engines runs on two tracks: vehicles showing diagnostic trouble code P0016 get a full engine replacement, while others receive an oil change from 0W-20 to a heavier 0W-40 weight plus a new oil cap. Plaintiffs argue that fix is “egregiously inadequate,” noting failures have occurred even after dealers completed the repair, according to Hagens Berman’s summary of the complaint.

The $150 million settlement referenced in the case is a different matter entirely, covering a different engine: GM’s Generation IV 5.3-liter LC9 V8, used in 2011-2014 Chevrolet Avalanche, Silverado, Suburban and Tahoe and GMC Sierra, Yukon and Yukon XL models. U.S. District Judge Edward M. Chen granted final approval in October 2025, with eligible owners receiving an average of more than $3,300 per vehicle, according to Beasley Allen’s coverage of the settlement’s approval. That case, over piston-ring wear causing excessive oil burn, is now closed. The L87 litigation covering newer trucks and SUVs is not, and for owners of 2019-and-newer GM trucks watching that older case get resolved, it’s a reminder that a settlement on one engine doesn’t close the book on the next one.
