General Motors Air Conditioning
This MDL consolidates consumer class actions alleging that air conditioning systems in certain Chevrolet, GMC, and Cadillac truck and SUV models suffer from a common defect causing cracking, refrigerant leaks, pressure loss, and system failure, and that the manufacturer's efforts to repair the defect under warranty did not resolve it. Centralized in the Eastern District of Michigan in 2018, the docket brings together claims from purchasers and lessees across multiple states and carries 15 pending actions.
What has driven this docket's timeline is a sustained and genuinely contested class-certification fight: courts overseeing the litigation have pressed both the manufacturer and the plaintiffs on whether the alleged defect and its effects can generate common answers across proposed statewide classes covering thousands of vehicle owners, the central predominance question in any product-defect consumer class action. That question, rather than a settled liability determination, remains the primary driver of the docket's resolution timeline, since the answer determines whether the case proceeds as an efficient, aggregated class matter or fragments into a larger number of smaller, individualized disputes.
For anyone tracking how automotive product-defect consumer class actions resolve, this docket illustrates a common pattern: years of litigation concentrated on the class-certification question itself, with the underlying defect allegations largely undisputed as a factual matter while the legal question of common proof across state-law variations remains open. Criterica Intelligence's platform tracks this class-certification-centric resolution profile across consumer product-defect MDLs, since the certification outcome often matters more to case value and timeline than the underlying defect theory alone.

The litigation has centered on a genuinely contested class-certification fight over whether the defect claims can generate common answers across proposed statewide classes, rather than the underlying factual defect allegations themselves being in serious dispute.
