Mazda class action lawsuit overview:ย 

  • 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.ย 
  • Why: Cauller claims Mazda knowingly sold certain vehicles with a dangerous engine defect.ย 
  • Where: The class action lawsuit was filed in California federal court.ย 

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

Plaintiff Matt Caullerโ€™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.ย 

Cauller says the alleged engine defect causes the engine to leak coolant, which causes the engine to overheat and leads to โ€œcatastrophic engine failure.โ€ย 

โ€œBecause of the Engine Defect, Mazdaโ€™s advertising about the safety and dependability of the Class Vehicles is untrue and materially misleading,โ€ the Mazda class action says.ย 

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.ย 

Mazda admits existence of engine defect, class action claimsย 

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 vehiclesโ€™ warranty, or issue a recall, the Mazda class action alleges.ย 

โ€œMazda has long known of the Engine Defect. It has amassed years of research, data, and Engine Defect warranty claims,โ€ the Mazda class action claims.ย 

Cauller claims Mazda is guilty of unjust enrichment and fraudulent omission and violating Southย  Carolinaโ€™s Unfair Trade Practices Act and state codes regarding breach of express warranty and breach of implied warranty of merchantability.ย 

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.ย 

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.
