New 2020 CX9 GT developed a humming noise that increased with speed, but not at idle. Mazda service technician drove around with me and he thought it was the tires. But when I had them look further into it they called and said it was a transmission problem and I would need a new transmission. Under 10k miles it should be under warranty.
I figured the turbo would become an issue before anything else! Big OUCH on my opinion of Mazda reliability. Otherwise the car has been excellent! I thought I would share since I could not find anyone else with the same issue.
