The engine in my Mazda blew with no warning. I got in my car after warming it up and noticed my check engine light on, which wasn-€™t unusual because it has came on before with a loose gas gap warning, so I put it in gear and drove less than 50 ft before it started making noises. I immediately turned around and came straight home and turned the car off. It started up and all but wouldn-€™t hold power. I got multiple opinions and no one could tell me why it my engine gave out with no warning. It was current with oil changes and all. I did purchase it used from Beardmore and didn-€™t have it for a full 2years.

Water pump is cracked and leaking through weep hole, to no fault of the driver. The vehicle has over 214k miles on it and the mechanic informed us that this is common in this vehicle of this age with that many miles on it. Luckily we caught it before the leaky coolant mixed in with the engine oil and caused the engine to seize up, which after doing my research I'm realizing is a common issue with this make and model of vehicle. No mechanic in our town will fix it since the entire engine has to be taken out in order to get to the water pump. It's just too risky apparently. The only reason I'm reporting is because after doing my research I've found that water pumps breaking is a common issue with 2013 Mazda CX-9s.

Car began shuddering/shaking and check engine light went on. Booked appointment at Mazda dealer. Upon inspection they found a significant amount of coolant had leaked into engine and timing was jumping. Was advised it should not be driven as the engine could freeze at any moment without warning. The technician provided a video inspection of car showing large amount of coolant inside car's engine. An oil change had been performed less then 2 months earlier (5/19/2022) and no issues were noted.

I was sitting in the car rider line and my engine started making this loud noise. I looked down at the temperature gage and it started over heating. I went to go pull it over and I noticed that the check engine light came on that's when I was turning in the parking place the engine stalled and i turned the car off. I took it to a local shop and he told me that I need a new engine, because apparently whoever made the car decided it was a grand idea to put the water pump in with the engine. A engine cost about $4,000. Because the water pump is in with the engine it costs about the same as replacing the engine. Thank god I was driving down the main road whenever it happened because me and my daughter could have gotten hurt. Insurance won't pay for it. I don't know how I am going to pay for it.

Headed out to the store and engine was running rough and CEL was on. Thought it was bad gas because I just put a few dollars in. Added gas treatment and topped off tank and continued to store. Stopped at Advanced Auto near the grocery store so they could pull the code. It was a P0016 - cam position sensor. If that was bad it would explain rough idle. Leaving to come home engine was a bit rougher and realized there was no heat blowing. Only 4 miles from home so kept driving figuring thermostat was broke but was concerned 2 things bad at once. About a mile up the street complete loss of engine power, power everything was on. Had no power steering or brakes. Managed to coast into a parking lot. Shut off engine, and waited. Restarted engine, notice temp gauge starting to go higher - pulled back onto street but again lost power steering and brakes. Managed to pull into parking log of auto repair shop and left vehicle there. Contacted Mazda next day - they agreed it was mostly the water pump failure and could possible fix it. Arranged for tow later in the week. Mazda inspected and said they could not repair. Needs new engine $5000-6000.

The water pump went out with no notice or warning, flushed all the coolant/water into the engine and failed. Over a $2K repair for a known engine defect with active lawsuits out. A Mazda water pump lawsuit alleges 2007-2016 Mazda CX-9 and 2009-2013 Mazda6 vehicles are equipped with pumps that suddenly fail and cause catastrophic engine failures. The proposed class action lawsuit alleges the vehicles lose engine power and fail to accelerate and maintain speed. The vehicles also allegedly can't readily control steering and cannot fully engage the brakes. The plaintiffs claim the vehicles are at risk of serious crashes because Mazda has failed to disclose the alleged water pump defects. Please investigate for a recall asap!

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 power steering and power breaking suddenly failed while traveling at about 40mph. The check engine light had gone on a few minutes before the car had this incident. With considerable force on the brake I was able to get the car to the side of the road. It was towed to a garage where they told me a 'water line had broke resulting in the engine becoming suddenly filled with coolant'.

The radiator failed internally with no warning, no leaks no engine light nothing, mixing antifreeze into the oil and destroying the engine. My machine informed me that there was no way of me knowing this was happening and its faulty the way they make the radiator it causes this to happen. Now my radiator is bad and my engine. I was driving and suddenly a noise started then power went and pulled over and wouldn't start again. No warning nothing. No leaks no engine light prior.

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.
