NHTSA 5-Star Safety Rating
Engine and brake complaints dominate what 2014 CX-9 owners report. On the engine side, water pump failure comes up repeatedly, with owners describing coolant mixing with oil and resulting damage significant enough to require engine replacement. Several owners note the failure arrives with little or no warning, no check engine light, no obvious symptoms, before the vehicle simply shuts down. A handful report the car dying at highway speed without prior indication. Brake complaints center on reduced stopping power, with owners describing a noticeably soft or unresponsive pedal that requires far more force than normal to slow the vehicle. Some of those reports mention an unusual noise accompanying the brake pedal effort. Powertrain complaints round out the top three reported categories, though owners in that group describe a range of drivability concerns including pulling or drifting while driving.

By System
The 2014 Mazda CX-9 has 3 recalls, the most serious being a Takata airbag inflator on the passenger side that can explode and send metal fragments into the cabin, posing a risk of serious injury or death — this recall applies to vehicles registered in high-humidity states and territories.
Two suspension and steering recalls also affect this vehicle. Water can leak into the front lower ball joints and corrode them over time until the control arm separates, causing sudden loss of steering. A related concern involves the steering knuckle, which can separate from the strut assembly and also result in loss of steering control.

What can fail
The passenger front air bag inflator may explode during a crash. This happens because the inflator's propellant degrades after years of exposure to humidity and temperature changes.
What the fix does
Dealers will replace your passenger front air bag inflator with a new one at no cost.
