A recently filed class action lawsuit alleges that General Motors (GM) marketed vehicles containing a defective engine prone to spontaneous failure.
Plaintiffs Mezanur Rahaman, Gerald Reed, and Farrah Forrest allege the engine defect impacts 2021–2024 Cadillac Escalade and Escalade ESV; Chevrolet Silverado 1500, Suburban, and Tahoe; as well as GMC Sierra 1500, Yukon, and Yukon XL models.
According to the plaintiffs, the alleged defect may cause the engine to fail abruptly and without warning, thereby increasing the likelihood of an accident.
The plaintiffs seek to represent a nationwide class of consumers who bought or leased the affected vehicles, along with subclasses in Pennsylvania, New Jersey, and New York.
The plaintiffs allege GM sold nearly 600,000 vehicles with a defective engine linked to issues in the connecting rod or crankshaft.
The plaintiffs allege GM has failed to offer a sufficient or lasting fix for the defect under its express and implied warranties.
The plaintiffs allege that General Motors is liable for breach of express and implied warranty, fraud, and unjust enrichment, as well as violations of the Pennsylvania Unfair Trade Practices and Consumer Protection Law, the New Jersey Consumer Fraud Act, and New York’s General Business Law.
The plaintiffs are seeking a jury trial, court-ordered relief, and compensatory, statutory, and punitive damages on behalf of themselves and the class.
The lawsuit, Rahaman, et al. v. General Motors LLC (Case No. 4:25-cv-11925-SDK-KGA), is before the U.S. District Court for the Eastern District of Pennsylvania.
