Mazda Cx-9 problem 130,000 miles-on November 25th, as I was dropping my children to their schools, the defrost suddenly stops working. I try to turn the fan/heater all the way, but to no avail. I had to use a towel to wipe the windshield. As I pulled into a curved side, the engine turns off, I turned the ignition key to off, then starts the engine again, and the engine light comes on. I pulled out and drove about six hundred feet and parked. I call a mechanic and I drove it again for a mile to the shop. He opens up the hood and pour in some coolant and all the coolant were on the floor. He immediately told me that coolant leaks and oil is probably mixed and causes the engine failure. He told me I had to change the engine, because fixing it will cost me over ten grand. I drove it home, then the following morning, I took to a different shop, they did the diagnosis and relate the same story that check codes showed three codes: P0016, crank position sensor correlation bank one sensor a. 1285 cylinder head over temperature, 1299 cylinder head temp protection. The codes indicate an overheat scenario that resulted in engine shut down. They check oil and found milky substance instead of oil. Pressure check for coolant leak pushed milky oil out of dipstick tube. Head gasket has failed due to overheating and the coolant has contaminated the engine oil. Their recommendation is to replace the engine, assembly and flush cooling system. Their total estimate is $10,900. I can't afford to pay for this service repair. I cannot even spend that much of money on another car. We bought this car thinking that it will take us for some time before we'll need another car. I contacted Mazda customer experience, and their response was, "wish there were never part failures", now, I'm stuck. So this is my story!!! safety issues: Sudden engine shut off, defrost malfunction and steering wheel.
I'm thankful I was not going 75mph on the highway with my children in my car instead I was driving 30 mph coming to a stop at a red light on a small city street my Mazda Cx-9 without a warning started hiccuping and came to a complete stop and not able to power up again we had it towed to a Mazda dealer was told our make model of car has a tsb code issued code # 01-026/11 dealer told us car needs new PCM (computer) and new coils they weren't sure if coils ruined PCM or PCM damage coils. Spoke to manufacturer they admitted they have seen issue but that my car is 40000 miles over warranty. I have owned other cars and all my friends have cars I have never heard of this happening. I hope this gets investigated there are loads of Mazda's just like mine on our roads I was very lucky to be going so slow this could have gone very bad. I have done some research online and there are loads of stories like mine. With no warning signs at all
When starting the vehicle there is a loud sound coming from the engine for 2-3 seconds. It doesn't happen all the time, but it sounds like a card going through bicycle spokes and is accompanied by a high rev sound. This sound also happens randomly when driving. It happens directly after the vehicle automatically shifts into a new gear, and is accompanied by a loss of power until the rev sound and card in spokes sound goes away. The power of the vehicle is normal until it makes that sound.
