Purchased a 2012 CX-9 GT. I'm fussy about build quality. I didn't find a single quality issue with my car. Every seam, all the paint, every fit was perfect, inside and out. An excellent value and definite upgrade from others in it's class...and I checked them all. The 20" tires are "firm", but I expected that. Mileage combined has been about 23.5. Also what I expected. I leave the 3rd row folded down to increase capacity. No problem. My local dealer provided the best buying experience I've ever had. Service dept is excellent and every employee has been friendly and helpful. Maybe I'm just lucky?
We've had our CX-9 for just a week and we love it! It is very comfortable and it does not feel like we are driving a mid-size SUV. When going on the freeway, the accelerator is extremely responsive. The turning radius is surprisingly sharp, which makes parking in tight spots and u-turns effortless. The ride is also very smooth, even with the 20 inch rims.
Mazda is having an issue with brake boosters in the CX-9. Mine failed today at 52K miles. I couldn't stop the car pulling out of the garage and rolled it into my side yard. I took it into the Mazda dealership, and they know there's an issue. There's a service bulletin, and they replace the brake booster for free. I can't believe they haven't recalled the car - this could cause a serious accident. There is an issue with the diaphragm in the brake booster failing in hot climates. I live in Ohio. It can get hot here, but give me a "brake" - literally. The dealership cannot tell me if the new brake booster has the same issue. I'm assuming it does since I've read about these failures happening in the CX-9 since this design was released. The car is at the dealership every 5K miles for maintenance - they didn't catch it there either. You'd think they would check since it's a recurring issue. I'm beyond disappointed Mazda allows the car to be on the road with this type of failure possible. I wouldn't buy this car again.
Just sold 2012 CX9 after three years (35,000 miles). Decent SUV for price. Pros: Appearance, good performance/handling, interior space. The CX9 looks sporty and handles/accelerates well for a large vehicle. Large interior space with decent room in the third row. Cons: Gas mileage, ride comfort, cabin noise, The CX9 does not get anywhere near the advertised gas mileage. 18.5 combined driving and 21.5 on strictly highway trips. Not a very comfortable ride if you are in the car for longer than 1 hour. Suspension felt stiffer than other large SUVs and could feel all bumps on road. Car had small annoying rattles on both interior/exterior.
We bought this car new in 2012. I waited this long to review to make sure I just wasn't being reactive. This car has it all. As a 'soccer' mom, I'm constantly picking up and dropping of kids, swapping car seats, and running errand. The sliding 2nd row makes it easy getting car seats in and out, and fitting even adults in the 3rd row. The power liftgate is handy. There's plenty of room for fitting our 60lb dog and all our bags back there (though I would recommend buying a liner). This week was the first time really testing it on snow and it did great. Not only is it quick, agile, and fun to drive...It's just plain makes life easy. I recommend this car to everyone!
