“I purchased a 2014 Mazda cx nine a year and a half ago. The other day I was driving and I don't know where my fan got really loud so I pulled over and turned up the heat and turned off any AC. All the sun steam started coming out of my engine and the car died. After towing it to the local dealership I was told that I had two options. I could either buy a brand new car or pay $13,000 to have it repaired. Apparently the water pump broke and the engine seized up. I had absolutely no warning. …”
NHTSA complaint #11403345, filed 2021-03, 80,000 miles“My wife took our 2014 Mazda CX-9 to liberty Mazda for a check engine light that came on the evening before she already and an appointment for another issue. She asked them to check the light as well. After their findings they told sue the car had a catastrophic water pump engine failure. This water pump is located inside the timing chain cover and leaks coolant in to the engine. At this point we were handed over to a sales rep. Who informed us this was a foolish design with the water pump located in the powertrain behind the timing chain cover. …”
NHTSA complaint #11252193, filed 2019-08, 108,000 miles“I noticed a rough noise when I started the 2014 Mazda CX-9. I chose to ignore it thinking it was because of the cold weather. Got to the highway on the way home to kansas city from columbus, oh. Several miles later when filling gas, I noticed a weird smell like that of a burning rubber or coolant. The car got me home same but I noticed slight smoking from the engine when I got home.took it to the mechanic and he advised it was the water pump. He didnt have the right tools to replace it so I took it to a Mazda dealership who advied getting a new engine. …”
NHTSA complaint #11289733, filed 2019-12, 114,000 miles“I was slowly approaching a stop light when our 2014 Mazda CX-9 started having vibrations, which at first came from underneath, between the driver's row and the 2nd row passenger. It immediately felt as if the car's engine was about to fail. I managed to make that right turn, carefully stepping on the brakes, and crossed a rail-road crossing. The car was running at a speed of 20 MPH. I slowed down to make another right turn towards my destination, then the engine abruptly died. The battery and check engine lights suddenly lit up on the dashboard. …”

The vehicle all of a sudden started shaking, the engine shut off and the vehicle lost power. The engine is now damaged beyond repair. The vehicle has an internal water pump and the owner's manual does not recommend any maintenance to the water pump. This vehicle had all of the recommended maintenance completed at an authorized Mazda dealer, the vehicle was in a parking lot when the engine unexpectedly shut off. …”
