2015 Mazda CX-9 owner complaints

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.

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.

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 and apparently many others) is located inside of the engine and behind the timing belt components failed without showing any prior signs of failure due to the water pump being hidden inside of the engine. The coolant had been leaking into the oil pan and mixed with the oil but be

The front brakes make a grinding noise when repeatedly applying the brakes when going downhill or slowing repeatedly from speeds of 65 or so. I believe the brake parts become hot and create something google searches call "judder". I have had the steering will start shaking as well. After repeated requests to Mazda corporate and visits to two dealers, Mazda claims the brakes work as designed. One service manager at browning Mazda stated the front rotors are too small to stop a car of this weight, but this statement is not written. Regarding the vehicle stability control, when I turn left and go downhill from my driveway at a slow speed of approx 10mph, I usually have no throttle control. I need to apply the brakes to regain any control of the throttle. Once again two dealers tell m

2015 transmission problem Mazda dealership unable to affect because transmissions are no longer made for my model

Tl* the contact owns a 2015 Mazda cx-9. While driving various speeds, the driver's seat moved back and forth without warning. The dealer (hall Mazda virginia beach, 4372 holland road, virginia beach, va 23452, (877) 438-1954) repaired the seat and seat frame twice, but the failure recurred. The vehicle was not repaired a third time. The manufacturer was notified. The failure mileage was 69,000.

The transmission occasionally would make a clunk sound when shifting from n to d. This problem has been going on since the car was bought.

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 able to get to my destination safely. We took the vehicle to a shop, and told the mechanics the issue, but they could not re-create what happened. We stopped driving the vehicle as much after this first encounter. A couple of months later, the issue still persisted, and we took it

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.

I've only had my Mazda for 10 months and have had the same problem twice. The right headlight socket has melted and rendering the bulb useless. I noticed the socket had been spliced into the old harness so I took it to the local Mazda dealer service. They gave me an estimate to install a complete new harness. To remove the light fixture, the bumper will need to be removed. The estimate for this was $643.25! I purchased the wiring harness and with help installed it through the ports in the rear of the fixture in january 2019. Recently, the light stopped illuminating again only to find this same socket has melted as the previous one did. If this pattern persists, it could cost $1300 per year to have Mazda fix it. The spliced harness tells me that this has been a problem with this vehicle

The wiring harness on the headlight for my Mazda CX-9 has and continues to melt, causing the bulb to be useless. The only issue that will seem to correct this issue is installing new headlights. According to my research this is a problem that is common to Mazda CX-9 vehicles.

Tl* the contact owns a 2015 Mazda cx-9. While driving 68-70 MPH, the vehicle stalled. In addition, smoke was detected from the engine and the check engine, battery, and oil warning indicators were illuminated. The vehicle was towed to an independent mechanic who stated that the water pump blew up and coolant entered the engine. The contact called heritage Mazda bel air (1800 belair rd, suite c, fallston, md 21047, (410) 575-1351) and was informed that the repairs were not covered under the warranty.

My brake peddle began hissing and my vehicle does not want to stop when in motion, I took my vehicle to a Mazda dealership and they stated it was the brake booster which is a problem Mazda has been having, but my vehicle is not in the years specified in the warranty extention. The dealership stated Mazda is not willing to help or fix the issue, and that we would have to pay out of pocket. It is the exact same problem the earlier models have been experiencing and are being fixed and mine is not. Maxda is aware of this defect and will not help me. My vehicle only has 58k miles and should have theses issues. The hard brake peddle and hard braking occurs on roadways, in driveways anytime the vehicle is moving. It is unsafe and I have avoided several collisions.

I purchased the car new on september 18,2015. Having the car for 3 months I have been at the service department 3 times. I got home the first day and the belt was not registering and was making noise when I had it on. The last 2 times I continue to hear noise coming from the car. The noise is heard from underneath and it has to be driven for significant amount of minutes before the noise goes away. I recorded the noise on november 28,2015 and called the dealer very upset because its a problem that's not being addressed and fixed. I dropped the car off on monday november 30,2015 and was told yesterday december 1,2015 that they dont see the problem.this is a new car and I never test driven before buying. I need help. I have the recording but I cant attach it on here.
