2012 Mazda CX-9 engine problems

Filed Oct 28, 2022 · Engine, Steering · MN

After hearing low rumbling sound and smelling burnt oil, car was taken to dealer for check up. They informed me of known issue, front PTU leaking oil due to design flaw that put the PTU so close to the exhaust. I am seeing that other owners of this model are also reporting fires due this same exact problem, apparently unbeknownst to me Mazda has provided extended warranty up to 90k miles but not actually informed the owners of this as a potential catastrophic problem. my personal review has informed me that fire seem to be most common between 110,000 and 130,000 mile ranges.

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.

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.

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.
