“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. …”

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.
