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.Owner report · Engine · Sep 2023
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.Owner report · Engine · Jan 2023

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.Owner report · Exterior Lighting · Aug 2021
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.Owner report · Power Train · Jul 2021
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.Owner report · Engine · Oct 2020
