2015 Mazda CX-9 Engine problems

My Mazda has been serviced regularly, in fact my next oil change isn't for 2,000 more miles. I was driving when I heard this weird noise. I looked at the dash and the oil light was flashing and the temperature was over heating. I could also feel the vehicle getting sluggish. I pulled over on the interstate. All the lights were on by this time. I popped the hood and there wasn't any coolant in the resivour anymore. I let the car cool down and I added some water as I was 1 mile from the exit where there was a gas...

We have a 2015 Mazda CX-9 Touring with All-Wheel Drive (AWD). The issue that has been happening is a flashing check engine light (CEL) indicator showing up in the gauge cluster. This issue originally started in October of 2023. I was on the highway doing at least 55 miles per hour (mph). Before the light actually came on, I had already felt the vehicle shaking, and also noticed the acceleration was sluggish. In the blink of an eye, the CEL came on and started flashing. After that point, the CEL stayed on. I was...

The contact owns a 2015 Mazda CX9. The contact stated that while driving at approximately 55 MPH, the vehicle shut off. The contact stated that the engine was overheating. The contact restarted the vehicle, and the vehicle stalled again. The vehicle continued to coast into a parking lot. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the water pump, timing chain, cam phaser, timing chain tensioner, and an engine replacement were needed. The vehicle was not repaired. The manufacturer was not contacted. The approximate failure mileage was 124,000.

The issue is with the design of the Water Pump on this vehicle. From my understanding, this is a common issue with the 2015 Mazda CX-9. What happens is once the water pump starts to fail due to the design, the vehicle starts to stall randomly which poses a safety issue to my family when driving. The vehicle was inspected by a dealership in the area and was ultimately fixed. I was informed that the water pump has been redesigned by the manufacturer to prevent this issue from happening again.

My check engine light came on. Thought it was the oil needing to be changed. Oil was extra dark and muggy. Also notice antifreeze low. Fill up antifreeze and change oil. 2 wks later antifreeze back down low. Check engine still on. Got it diagnosed with auto scanner and says camshaft sensor. Went to autoshop, mechanic says it's not cramshaft sensor but water tank leak in engine which was picked up by camshaft sensor. I have yet to find out what else is wrong or if my engine needs to be replaced. For sure the water...

Engine failed suddenly while driving on a busy street. No lights were on, no warnings. Slight hum earlier that day, that was almost indistinguishable from the radio or other road noise. Steering and brakes not responsive. Had it towed to dealer who found that the water pump had failed which allowed coolant to leak into the oil. Dealer mechanic stated that the water pump is not visible to any mechanic without removing the entire engine, therefore would not have been able to see defects or problems ahead of...

Water pump failed and leaked coolant into oil. Known issue by Mazda but they have failed to warn consumers. Repairs roughly 4000 dollars. Luckily I caught before engine failed due to lubricant dilution from coolant. Potentially a very dangerous flaw.

2015 Mazda CX-9 with 93k miles: while driving in traffic, check engine light suddenly came on, the car began to shudder as I heard a loud knocking noises coming from under the hood, and then a sudden loss of power while trying to navigate through a busy intersection while trying to make a left turn left myself in danger of almost being struck from the vehicle behind me and an oncoming vehicle from the opposite direction due to me stalling out in the middle of an intersection. The water pump (unbeknownst to myself...

On December 14, 2015, I bought, a Mazda CX-9, at Sentry West Mazda located at 940 Boston Turnpike, Shrewsbury MA 01545. Unfortunately, the car's 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. On March 7, 2022 while driving the car to the...

I was driving into the highway and my vehicle just shut off. I was in the car with my children and I was scared that we were going to be rear ended. I had my mechanic look at the car and he advised me that the water pump leaked and the coolant leaked into the oil. I'm having another mechanic provide me with an estimate of how much the repair is going to cost. After the car shut off and I tried to turn it in again the batter, engine and oils light went off and I had the car towed to the local mechanic.

Engine light came on then my vehicle started over heating and leaking coolant. Vehicle was towed to dealership.After technician diagnosed the problem, I was told it was the internal water pump that caused fluid to mix with the engine oil ruining the engine. I was told I had three options: buy a new engine, buy a used engine or buy a new car. I was told that this was an issue with this year, make and model for several customers. I asked why a recall notice was not given to vehicle owners and was told it was not a...

We purchased a 2015 mazda cx9 with 30,000 miles three years ago. At the start of the month, the car suddenly overheated while driving and the engine failed! The mechanic said the water pump failed, the coolant mixed with the engine oil and the engine was done. $$7944.41 Additionally, the overheated engine caused the transmission fluid to burn to a point the the transmission failed. $$4864. This happened at 65,000 miles, 5,000 miles past warranty. After researching the problem, we learned that this is a common problem on mazdas that use the duratech engine. There are thousands of examples and a class action lawsuit.

Code p0016 came up one day prior to engine failure. 30 Miles after check engine line came up loss power. Upon inspection water pump failure at 85000 miles. Engine most likely toasted

While driving my 2015 mazda cx-9 on a very busy interstate, the check engine light appeared on the driver panel. I was traveling with my very young children, ages 4 and 20 months. Approximately 10 miles later, I started hearing a rattling sound under the hood. Shortly thereafter, my car stalled out as I entered my subdivision. My husband had to push the car to our driveway. I called aaa that same day and had the car towed to the dealership that services the vehicle. I was told that the water pump needed to be...

We bought this vehicle in june of 2015 and about 2 or 3 moths after I noticed that the rear driver side rotor had a deep scratch on it. They fixed it by sanding the rotor insted of replacing the rotor. Next time I brought was an oil leak on the front side of the motor about 4000miles. They said that the oil filter is loosed. So me and my wife went home having some pieceof mind that I brought the car to a dealership and they will do the right thing. But at 7000 miles I brought our vehicle for first oil change and...
