If you own a Chevrolet, GMC, or Cadillac vehicle equipped with General Motors’ 6.2L V8 L87 engine, recent developments could directly affect you. A General Motors V8 Engine Lawsuit has been filed, alleging a serious manufacturing defect that can lead to catastrophic engine failures. For California vehicle owners, this lawsuit is especially significant because it may entitle them to compensation under the state’s robust Lemon Law protections.
What’s the issue?
The lawsuit alleges that GM’s 6.2L V8 L87 engine—installed in numerous full-size trucks and SUVs—suffers from serious internal manufacturing flaws. In particular, the crankshaft and connecting rods may not meet proper specifications or could be contaminated by debris during production. These defects can cause total engine failure, increasing safety risks for drivers and resulting in expensive repair costs. GM has recognized the issue and announced NHTSA Recall No. N252494000, which impacts nearly 600,000 vehicles.
The Problem Behind the GM 6.2L V8 L87 Engine
The heart of the General Motors V8 engine lawsuit centers around allegations that the L87 engine—used in popular full-size trucks and SUVs—contains critical manufacturing defects. According to the complaint, during engine assembly, connecting rods and crankshafts may be produced out of specification or contaminated with debris.
This defect can cause:
- Sudden loss of power while driving
- Knocking sounds and rough performance
- Warning lights indicating engine trouble
- Complete engine shutdown, often with no prior warning
- The defect poses safety risks for drivers and passengers, can leave vehicles stranded, and often results in costly repair bills.

GM’s Public Position
While GM has launched a recall, the General Motors V8 engine lawsuit claims that these measures fall short of fully addressing the risks and damages owners have sustained. Some drivers report experiencing engine failures even before receiving recall notices, and others say dealerships initially dismissed their complaints as normal wear-and-tear.
GM maintains that its repairs and inspections will correct the specific defect. However, legal experts note that fixing these engines may not fully protect consumers who have already suffered repeated failures or diminished resale value.
