Water Pump problems of the 2012 Mazda CX9

My wife was driving down a city street when the car completely shut down and lost all power. Luckily, she was able to stop without causing an accident. We had car towed to an independent mechanic. After inspection we were told the water pump had failed causing coolant to leak into the engine and caused complete engine failure. We were quoted $8k-$10k to replace the engine. The 2012 Mazda cx-9 only had 99k miles, but unfortunately our extended warranty expired a few years ago, so Mazda was of no help. We were left to junk our car for a fraction of what it's value should have been. Apparently this is a known issue and we will be joining the current class action lawsuit against Mazda.

In oct. 2019 my Cx9 stopped while being driven. Found out the water pump (which is inside the engine) had gone out and destroyed my engine. This is a known problem of which Mazda has failed to make their consumers aware. I purchased this care new and all of my services had been handled by Mazda. No-one told me about this problem and I still had to pay just over 4k to get a new engine of the same stupid design put in my car. This is very dangerous problem. How many Mazda drivers have been injured or killed in crashes because the water pump destroyed the engine on a freeway and the car ceasing to move was the cause of an accident that totaled the car and as a result went undetected? the engines need to be recalled.

Tl- the contact owns a 2012 Mazda cx-9. The contact stated that while driving at various speeds the vehicle had suddenly shut off. The vehicle was towed to the local dealer kennedy Mazda(1411 ridge pike, conshohocken PA) who diagnosed that the engine was damaged due to a faulty water pump. The vehicle was towed back to the home and later repaired by an independent mechanic but the failure had reoccurred. The manufacturer was notified of the failure. The failure mileage was 109,000. Jft.

Vehicle stalled while exiting the highway, engine light on, noise from timing chain area, vehicle overheats, water pump failure pushes antifreeze into the oil compartment causing the engine to get damaged within minutes whiteout a warning. This is obviously a major very expensive safety issue.

While driving my Mazda car, it suddenly started bucking and check engine light came on. Car was towed to the dealership. Per Mazda mechanic, water pump malfunctioned forcing coolant into the engine. Feel this poses a significant safety issue as there was very little warning posing risk of accident, engine overheating and potential fire. This appears to be a common issue as multiple other posts reported.

I own a 2012 Mazda Cx9, which I purchased new. On Monday morning (November 12, 2018) my (check engine light came on) and so I took it immediately to the dealership for diagnosis. My car was running beautifully, so I just assumed with the weather change, perhaps the gas cap wasn't tightened, and they just needed to clear the codes. It turns out the water pump failed and apparently destroyed the entire engine. Which became apparent as I drove it to the dealership for diagnosis, per their recommendation. My car is well maintained based on the dealer recommendations and is consistently serviced at the Mazda dealership. The car is in fantastic condition with only 90,000. As an owner, I did everything by the book in terms of maintenance for my car. I am letting you know, Mazda has a serious problem and it's a safety issue, as well. If a water pump can just fail without warning and completely shut down an engine, that's not good. I think this is far more dangerous than the air bag recall, which is only a concern if you get in an accident. There is no warning on the water pump failing, as it's self-contained within the power train and the only way to check this part is by removing the entire engine, which leads me to believe this part was not designed to be a wear part. It's an engineering design flaw, that can cause bodily harm if it fails, because it takes out the entire engine and you lose control over the vehicle.

While driving my vehicle on the highway my car would not accelerate when I pressed on the gas. My rpm's went up to 4 and would drop down when I let off the gas. Within minutes my steering wheel locked up and the car basically shut down. I had to try and drift to the shoulder in high speed traffic. When I got to the shoulder the car started smoking. I had the car towed to Mazda dealership. They told me my water pump went and leaked fluid throughout the engine, resulting in me needing a new $8,000 engine. They told me that Mazda designed the Cx9 where the water pump is in the engine block behind the timing belt and it is not something they can easily inspect when I bring my car in for service. So when a water pump goes on these Mazda cx-9's it results in the consumer needing a whole new engine. They also stated that there are no indicators that will notify you if there is a problem with the water pump to avoid this from happening. The safety issue is that my car was on the highway at the time this occurred with vehicles going at high speeds. My car basically slowed down significantly and eventually stopped and I could not turn the steering wheel to better assist me getting out of the way of the high speed traffic.
