(March 16, 2022)
A group of 20 Mazda drivers filed a hefty class action lawsuit against the carmaker for a water pump defect that they say can lead to โcatastrophic engine failureโฆ at any time without prior warning.โ The defect has caused one fatal accident already.
The water pump defect occurs in the MZI Cyclone engine in the CX-9 for model years 2008 through 2015 and the Mazda6 for model years 2009 through 2013.ย
The plaintiffs seek to represent a nationwide class of all persons or entities in the United States who purchased, leased or own a class vehicle. There are 12 state-specific subclasses for California, Florida, Illinois, Louisiana, Massachusetts, Michigan, Missouri, North Carolina, Ohio, Pennsylvania, Texas and Virginia. There are also two subclasses related to specific California state laws.ย
Mazda allegedly knew about water pump defect since 2007
The defect detailed by the complaint involves the internal chain-driven water pump. The pump is meant to circulate coolant through the engine while the engine is running. However, the defect in question allows coolant to leak from the water pump into the oil pan and/or other engine components, mixing it with the engineโs oil and leading to destruction of the engine.
The water pump is located deep within the engine behind several other components and would cost more than $1,500 to repair or replace, according to the complaint.
Plaintiffs argue that they and the class were not told about the potential defect. However, Mazdaโs internal data indicates that the company began receiving reports of water pump failures in class vehicles by at least June 2007, according to court documents. Mazda received at least 58 warranty claims for failed water pump failures in 2009. Complaints were also made to the National Highway Traffic Safety Administration.
The plaintiffs seek class certification and approval of class counsel, declaratory relief, an order preventing Mazda and other defendants from continuing their allegedly unlawful behavior, injunctive and equitable relief, damages, statutory and civil penalties, pre- and post-judgment interest and attorneysโ fees.ย

2014 CX-9 119K โ water pump failure. Local Mazda dealer says $5,550 โ $6K to repair. I had it towed to dealer when the check engine light came on. Local dealer said they are familiar with this common problem and that Mazda USA is not helping. I filed a case with them and after 3 weeks was informed that Mazda will not assist with the repair.
We are dealing with the same exact thing right now! Except we brought ours in 2 months before for fluid leaking they said It was a lose line and tightened it and here we are two months later needing a completely new engine and transmission. 15,000 is what we were told it would be for for parts and labor. Mazda refuses to do anything!
I have a 2014 Mazda and my water pump went out
June 25, 2022
2014 Mazda CX-9 -102,500 miles โ Only serviced by dealer
Water Pump failed without notice โ Just started making a crazy clicking noise
Now at dealer for repairs taking over a month & @ a $6500 bill for parts/labor
:(
Dealer started repairs then found out engine had been compromised with metal though out the engine โ Now needs a new engine โ $12,000 and a 6 month wait for a replacement engine
CRAZY !!!
We just experienced same issue. The local dealer who is the only mechanic who serviced it was clueless. The vehicle was a 2014 CX 9 with 87000. We had vehicle serviced when recommended without fail only by dealer. I will never buy another Mazda again as they could care less.
This just happened to my family and I. 2012 Mazda CX-9.
We are experiencing this right now! We are hundreds of miles from home when 2014 cx9 shut off. Coolant in oil. 400$ tow plus hotel and rental car!
Yep mine went out back in 2009. Been sitting in front of my house since then. Mazda said it would be $11,000 to replace.
Replace the engine/waterpump
Replace the engine/waterpump
Same thing here for my 2013 Cx-9 at 110k miles. Always maintained at the dealer yet no one there ever thought to mention the problem or suggested a replacement within or even outside of the extended warranty to avoid the catastrophic failure. Please contact if lawsuit is still open.
mine too. at 108k. I just had my water pump replaced. The thing is there was no warning about the water leakage. very dangerous. I want to join the lawsuit as well.
I also have had my 2008 CX-9 water pump issue and Iโve talked to some other lawyer already but if I can get a response back that would be great I was thinking about selling a car but I donโt want to sell it if we get this lawsuit going
Mine went out today, with 108,000 miles.
