DiCello Levitt represents consumers in a nationwide class action lawsuit against General Motors LLC (GM) for selling and leasing vehicles equipped with dangerously defective 6.2-liter V8 EcoTec3 L87 engines. The lawsuit alleges that GM knowingly concealed a serious engine defect that can cause sudden and catastrophic engine failure—putting drivers, passengers, and others on the road at risk.

The affected vehicles include certain model year 2019–2024 Cadillac, Chevrolet, and GMC SUVs and trucks equipped with GM’s L87 engine, specifically:

• Cadillac Escalade and Escalade ESV (2021–2024)

• Chevrolet Silverado 1500 (2019–2024), Tahoe and Suburban (2021–2024)

• GMC Sierra 1500 (2019–2024), Yukon and Yukon XL (2021–2024)

Plaintiffs allege the L87 engine suffers from a latent defect in the crankshaft and connecting rod components. The defect can cause the engine to seize or fail without warning, resulting in a sudden loss of propulsion and increased risk of collision.

Despite receiving thousands of consumer complaints and conducting multiple internal investigations, GM continued to sell and lease vehicles with the defective engine and failed to disclose the defect to consumers, according to the complaint. In April 2025, GM issued a limited recall that relies on oil changes or replacement with similarly defective engines—an inadequate remedy that fails to address the underlying safety risks or compensate consumers for their losses.
