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.

    I bought CX-5 and have ghost touch problem. Ask dealership and they told me first they gonna check and then they will perform anything. It will cost me more than 800 above something.

  4. Maria Thomas says:

    I purchased a 2024 Mazda 3 I have about close to 5,000 miles on it, the infotainment system blinks out on me for every what reason that I start to speed up, I feel like the dealership should have known about their engine if itโ€™s being recalled and or faulty

    1. Jessica Vail says:

      My infotainment system would always cut off and on so I removed the SD card from it so it would stop.

  5. Andre Green says:

    I purchased a 2021 Mazda 6 and my infotainment system has been failing and when I drive in sport mode it seems like I have to manually shiftto the higher gears or the engine strains. Is there a way to check for recalls

    My 2018 cx9 is in the shop now with a cracked cylinder head. Leaking both coolant and oil. 93k mile

  9. Destiny D says:

    I am paying for a 2018 mazda CX-5 which is currently in the Mazda shop for the passed 2 months it only has 22000 miles on it and without warning one day smoke came out the engine. I took it to a mechanic and they said the engine head gasket is completely blown and that it was a known issue to take it to mazda. I called the Mazda and they said opened a claim and told me to bring it in to the mazda dealership to be serviced. I havenโ€™t recieved not a call or message about the status of my car.

  10. Denise says:

    Yes! This EXACT thing happened to me in January! Complete loss of the car! I drive a lot for work and need something reliable. I sunk the 10k it would have cost me for a new engine into a brand new car. Iโ€™m so disappointed. I loved my 2019 Mazda CX 9 turbo with the gorgeous red paint
