Mazda class action claims thousands of vehicles have engine defect (2024)

Mazda class action lawsuit overview:

• Who: Plaintiff Matt Cauller filed a class action lawsuit against Mazda Motor of America Inc. d/b/a Mazda North American Operations and Mazda Motor Corporation.
• Why: Cauller claims Mazda knowingly sold certain vehicles with a dangerous engine defect.
• Where: The class action lawsuit was filed in California federal court.

A new class action lawsuit alleges that Mazda knowingly exposed the purchasers of hundreds of thousands of vehicles to a dangerous engine defect.

Plaintiff Matt Cauller’s class action lawsuit claims Mazda failed to disclose that its SKYACTIV-G 2.5T engines equipped in certain of its model year 2018-2021 Mazda6, 2021-2024 Mazda3 and CX-30, 2016-2023 CX-9, 2019-2024 CX-5, and 2022-2024 CX-50 vehicles were defective.

Cauller says the alleged engine defect causes the engine to leak coolant, which causes the engine to overheat and leads to “catastrophic engine failure.”

“Because of the Engine Defect, Mazda’s advertising about the safety and dependability of the Class Vehicles is untrue and materially misleading,” the Mazda class action says.

Cauller wants to represent a class of South Carolina consumers who purchased or leased in the state a class vehicle with a SKYACTIV-G 2.5T engine.

Mazda admits existence of engine defect, class action claims

Mazda has admitted to the existence of the engine defect via a series of technical service bulletins, yet has failed to warn consumers, extend the vehicles’ warranty, or issue a recall, the Mazda class action alleges.

“Mazda has long known of the Engine Defect. It has amassed years of research, data, and Engine Defect warranty claims,” the Mazda class action claims.

Cauller claims Mazda is guilty of unjust enrichment and fraudulent omission and violating South Carolina’s Unfair Trade Practices Act and state codes regarding breach of express warranty and breach of implied warranty of merchantability.

The plaintiff demands a jury trial and requests declaratory and injunctive relief and an award of actual and statutory damages for himself and all class members.

A group of consumers filed a separate class action lawsuit against Mazda earlier this year over claims the automaker sold certain vehicles equipped with defective infotainment systems.
