General Motors asked a Michigan federal court to dismiss a second amended class action complaint alleging valve-train system defects in various GM vehicles.
As noted in a joint discovery report recently filed by the parties, the plaintiffs allege a defective valve-train system in any 2014-2021 Buick, Cadillac, Chevrolet, or GMC Vehicle equipped with a 5.3L, 6.0L, or 6.2L V8 engine. Plaintiffs filed their second amended class complaint with approximately 82 claims, including breach of warranty, unjust enrichment, common law fraud by omission/fraudulent concealment, and violations of consumer protection laws. The alleged defect results in engine noises and engine misfiring, as valves fail to appropriately close and open, resulting in the vehicles stalling, surging, or losing power while driving. The Plaintiffs believe discovery will show a single valve train defect exists that affects various valve train system components, including the lifters, rocker arms, and valve springs. GM, as further noted in the discovery report, denies the allegations and specifically denies the vehicles at issue have a singular “valve train defect.”
On April 12, 2023, the court reminded the parties they could commence with discovery pending resolution of GM’s motion to dismiss the plaintiffs’ most recent complaint, filed in March 2023.
The case is Danny Harrison et al. v. General Motors, LLC, case number 2:21-cvc-12927, in the United States District Court for the Eastern District of Michigan.
