Water Pump problems of the 2013 Mazda CX9

Water pump failed and impacted my engine as well. I just brought my car in as well 10/20/2020 no mention of this issue. Beginning in 2007 and continuing through the 2016 model year, Mazda has incorporated its mzi cyclone engine (the �cyclone engine�) into hundreds of thousands of vehicles, which include the cx-9 for model years 2007 through 2016 and the Mazda 6 for model years 2009 through 2013. The cyclone engine contains an internal chain-driven water pump, which means the timing chain is connected to the water pump and provides the power the water pump needs to circulate coolant through the engine when the engine is running. The chain-driven water pump is located internal to the cyclone engine, behind numerous engine components, including the timing chain cover. Unbeknownst to purchasers and lessees of these vehicles, the cyclone engine contains a defect in design, manufacturing, materials and/or workmanship that causes the water pump to suddenly and prematurely fail well-before the end of the useful life of the engine, which leads to catastrophic engine failure or a costly replacement due to the water pump's inaccessible placement in the engine. When the water pump prematurely fails without warning, coolant is able to leak from the water pump into the oil pan and/or other engine components, allowing it to mix with the engine's oil. The mixture of engine oil and coolant circulates throughout the engine, leading to destruction of the engine. Despite having knowledge of this defect, Mazda continued selling defective vehicles, failed to disclose the defect to owners and lessees, has not issued a recall, and has not remedied the issue and/or compensated owners and lessees of the defective vehicles.

The contact owns a 2013 Mazda cx-9. The contact stated while the vehicle was at a stand still at a traffic light, the vehicle stalled without warning. The vehicle was towed to an independent mechanic but not diagnosed nor repaired. The vehicle was then towed to holiday Mazda located at 416 n rolling meadows dr, fond du lac, WI 54937, (920) 322-2550, to be diagnosed. The contact was informed that the water pump and timing chain needed to be replaced. The vehicle had not been repaired as of yet. The manufacturer had been informed of failure. The failure mileage was approximately 74,500.

In 2011 we leased a Cx9 and we enjoyed it so much that we decided to purchase a Cx9 in 2013. Just a couple of weeks ago I had an experience that was very frightening. I was driving and realized the heat was not coming on and that was unusual. The check engine light came on and soon after the car stopped running. I am fortunate that I was not on the highway and was able to pull over to the shoulder. I needed to have the car towed and we had it brought to Mazda in danbury, CT. We found out the next day the engine needed to be replaced. Needless to say, we were shocked and then very upset to find out that it would cost 10,000 dollars to repair. We have had our car serviced regularly by colonial Mazda in danbury, CT. Now we have a car that is worth nothing. Now we are put in a position to replace our car and have nothing to turn in to defer the cost. With research we have found that due to the design of the engine many Mazda Cx9 have had the same problem due to the water pump leaking, the transfer case leaking, and antifreeze going into the engine. In our opinion, and apparently to many cases we have read online this should have been a recall. This is something that should be looked in to for the safety of others. Fortunately, I was on a side road, someone else may not be as fortunate. The design of the engine if flawed and is more than likely why Mazda is not having a recall, because it is too expensive to repair.

Water pump caused antifreeze to mix with motor oil causing the engine to have to be replace on three occasions within 6 months.

The vehicle was being driven at the time on a busy freeway. When started overheating with no warning. The vehicle then cut off on freeway with traffic behind me at a fast speed. Thankfully I was able to get to shoulder. Towed car to shop and was told that Mazda has faulty water pumps and that my engine was destroyed due to coolant leaking into my oil with turned it to a thick mud. New engine needed. I researched online and there are countless consumers complaining of same issue with Mazda. This is extremely dangerous for your car to just stop when traveling at high speeds or traveling on any highway there needs to be a recall on this faulty water pump inside of the Mazda engine. I believe some one soon will be injured or killed by this issue! thankfully it wasn't my child and I.

The vehicle was being driven at the time on a busy city street. We noticed some noises which was sounding like metal clanking. This became louder immediately in the span of 5mins and the temperature sensor went off on the dashboard. The vehicle was becoming unresponsive to brakes in the middle of commute traffic. Luckily we got the vehicle stopped on the side of the shoulder without any injuries to anyone. Upon getting the vehicle checked by a ase certified mechanic, it was diagnosed that the internal water pump (suggested as a bad design by them and many others have reported similar stalling situations on the internet) somehow mixed up the coolant and the oil forming a sludge and was unable to control the temperature and lack of lubrication caused the metal clanking. This has rendered the vehicle completely inoperable only after 5years. Seems like engine needs to be replaced. This raises serious safety concern that if this happened on a highway or in the midst of traffic, there could be serious loss of life or injury to the passengers. Upon checking with Mazda, it was ruled that there is no recall for something like this yet. This stance from Mazda is being utterly not responsible for their design flaws and putting a product out in the market.
