On November 19, 2025, the Honorable Andre Birotte Jr. of the United States District Court for the Central District of California entered an Order granting Plaintiffs' Motion for Class Certification. The Court granted Classes of all persons who purchased or leased a Model Year 2016-2020 Acura MDX in the States of California, Louisiana, Massachusetts and Utah. Plaintiffs allege that there is a defect in the engine wire harnesses connecting the components of the throttle system, causing a loss in connectivity and resulting in unintended vehicle deceleration, engine stalls and hesitations, abrupt shutdowns and shifts into neutral while driving.
On February 18, 2026, defendant American Honda Motor Company filed a Petition for Permission to Appeal Pursuant to FRCP 23(f). On March 18, 2026, the Ninth Circuit Court of Appeals denied the petition.
Notice of the pendency of the class action will be disseminated within the next few months.
The Plaintiffs are represented by James C. Shah, Natalie Finkelman Bennett and Kolin C. Tang of Miller Shah LLP and Christopher E. Stiner and Tina Wolfson of Ahdoot Wolfson.
