Live Poll

Should automakers be held legally responsible for transmission failures in late-model family vehicles?

On September 15, 2026, a class-action lawsuit was filed against General Motors in the U.S. District Court for the District of Delaware. The legal action alleges that certain continuously variable transmissions in Chevrolet and GMC vehicles suffer from power loss, slipping, and dangerous acceleration delays.

Why it matters

The lawsuit seeks a court-ordered safety recall to address these alleged transmission defects, which plaintiffs claim endanger drivers across the United States. If successful, the case could force a significant repair or reimbursement program for hundreds of thousands of vehicle owners.

The lawsuit encompasses 2019-2025 Chevrolet Malibu models, 2021-2025 Chevrolet Trailblazer units, and 2024 or later Chevrolet Equinox and GMC Terrain vehicles. These models are cited for transmission hesitation, slipping, and unexpected power loss.
