Excellent vehicle

I purchased this vehicle used (Touring trim, 2WD) in 2017 when it had 24,000 miles on it. The price I paid was excellent compared to similarly equipped competitors (Honda, Toyota). I'll get the standard criticisms out of the way first... This vehicle has a small touchscreen and hard plastics in the dash. My previous vehicle had hard plastics and no touchscreen (or even Bluetooth) so for me there was no issue. Once you get past these issues you have an excellent vehicle. I love that it drives sporty, gets about 20 mpg combined gas mileage in the time I've owned it, I carry 7-8 people (4-5 who are kids) without trouble around town, and most importantly it has been incredibly reliable. In fact, 50,000 miles of driving and not a single repair, ever. Only standard maintenance and this vehicle runs like a charm. I place a premium on vehicles that last without troubles. I also love the blind spot monitor and backup monitor. If function, reliability, good pricing, and sportiness are your priorities, this car will be great. If you want aesthetics like soft touches and great electronics, not so much. I chose the former but I can understand everyone has different interests with their vehicle choices. Overall, I highly recommend this vehicle. Best wishes on your vehicle selection.

Basically an AWD car.

While the CX9 has a nice strong V6, it is far too delicately built to be classified as a 7 passenger "SUV". Loaded up with 2 adults, 3 kids and a bunch of gear, braking is downright dangerous. Had both rear wheel bearings replaced(at least under warranty), but then there was an off/on squealing from the rear. Reviews all comment on how well the CX9 handles for an SUV, an it does, because its really a big car, not an SUV. The most irritating locking system of any car ever made. I should have thought better when my wife asked the salesman when she first saw it, "Is this considered an SUV or a station wagon!!" After 2 years traded it in for a real SUV (Toyota 4Runner) and couldn't be happier.

The only thing really bad is the gas mileage

We knew that gas mileage was not going to be good before we bought the vehicle, but we got such a good deal on it that it somewhat compensated for the additional fuel cost.

Engine design flaw

I have owned my 2015 CX-9 for 5 yrs and loved it. I just paid it off six months ago and planned to keep it. However, unbeknownst to me, they designed the engine with the water pump inside the engine. If/when the water pump goes out it will leak coolant into your engine. No warning. I now have to buy a new engine since the water pump leaked coolant into my engine and it seized up while I was driving on the freeway. Check engine light came on and w/n 20 miles the engine was toast. I was on my way home from work heading to the mechanic shop to have it checked out.

Toxic Fumes Fill Car when Impending T-Case Fails

John, 12/22/2015
2015 Mazda CX-9 Grand Touring 4dr SUV (3.7L 6cyl 6A)

The CX-9 at first seemed to be a great car, very roomy and fairly comfortable. Fuel economy seems to be low for the size of car, averaging only 14-16 in-town, and 18 on the highway. The biggest challenge, and reason for the bad review is the Transfer Case. I have found several other reviews, matching this issue, and as far back as 2011. The transfer case failed at 12,500 miles, and filled the car with toxic oil fumes from the gear oil aspirating through the venting system. My wife and daughter got sick, and had respiratory issues through the evening and night. The technician informed me this was a known issue with the CX-9, and they have new T-Cases on hand due to how many they replace. The tech also informed me that this happens frequently at even a lower mile range, sometimes as early as 3,000 miles. Customer service was completely accepting of responsibility, and attempted to down play the "known" part of the issue. Even though it is easily found on several review sites, and the dealer had recent examples to discuss with me while I was turning it in for repair. The toxic fumes filled the car within a few seconds, and fully engulfed the interior with a stench that has not come out, similar to cigarette smoke. On a smaller, and a much less horrifying note, the Blue Tooth in this car takes up to five minutes to connect. Very poor blue tooth system.
