"Driving Matters" is the tagline Mazda uses to promote its CX-9 three-row family mover, casting it as the driver’s choice among the soccer-mom mobile crowd. Turns out that this slogan is quite apt; the CX-9 is particularly agile, comfortable riding, and quiet among affordable midsized three-row SUVs.

Reliability indicates how models have performed in the past, providing the basis for predicting how the vehicles will hold up in the year ahead. These charts provide the most comprehensive reliability information available to consumers. Based on information received from our latest subscriber survey for about 420,000 vehicles, our reliability history charts give you a rundown on how 2000 through 2019 vehicles are holding up in 17 potential trouble spots, ranging from the engine, transmission, and brakes to power equipment and the electrical system. NA indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Steven J., MA (2016 Mazda CX-9 Grand Touring 2.5-L 4 Cyl turbo)
Premature brake wear

"After leasing this car almost 2 years, i noticed a terrible groaning sound coming from the right rear tire area of my CX-9. The dealer fixed the issue which was a bad rear leaf spring. After fixing, the rattle/groan, the dealer told me that my rear brakes were almost worn out and needed replacing to the tune of $300. The car is less than two years old, has been driven mostly through the highway, and is basically babied. When I told the dealer that maybe the bad leaf spring caused the premature wear on the brakes, he actually laughed at me and said Hell no!. I don't ride my brakes, they just wore out extremely fast. I can't buy brakes for my CX-9 at an auto parts store either because the car is Too New and the dealers haven't issued out a part number for the brakes. I'm terribly disappointed."
