2014 Mazda CX-9 Complaints

The car started creating a noise like air was leaking when i apply brake. The problem continued to increase, and braking became harder and harder. The dealer indicated that I had to replace the brake booster. This is a 2014 CX-9. A NHTSA search showed that vehicles manufactured in 2013 were affected. My car was purchased in Feb 2014. I suspect this one too had that faulty equipment.

Sudden failure of water pump located inside the engine caused engine to shut down immediately while driving 70 mph on busy expressway. Extremely dangerous situation due to heavy traffic and high speeds traveled. Only by sheer luck were we able to coast across 4 lanes of traffic to an exit ramp and barely make it into a parking lot after crossing 2 more lanes on the frontage road. Very difficult to steer and brake due to no engine power. Repair cost was $4,433. Two subsequent follow up repairs for check engine light and oil control valve issues related to water pump failure were required and covered under initial repair warranty. Research on web indicates this is a common problem with this engine with many complaints occurring soon after 100k miles. In many cases customers reported having to replace the engine or sell the car for parts due to the high cost of repair. Locating the water pump inside the engine block was a terrible design fault and extreme safety hazard when it...

Water pump defect that led to pump failure, which led to catastrophic engine failure without any prior warning. The defect is in the internal chain-driven water pump. The pump is meant to circulate coolant through the engine while the engine is running. However, the defect allows coolant to leak from water pump into the oil pan and/or other engine components, mixing it with the engine’s oil and leading to destruction of the engine. Mazda’s internal data indicates that the company began receiving reports of premature water pump failures in vehicles identical to mine (mine is a 2014 Mazda CX-9) by at least June 2007, yet Mazda continued to sell the vehicle without fixing the defect and failed to warn customers of the defect. The owner's manuals say nothing about water pump maintenance because the water pump should last the life of the Mazda vehicle. My water pump failed and destroyed my engine at just a mere 72,400 miles. The water pump problem is caused by the elastomer bellow, which...

- Water pump failed causing coolant to mix with oil. This repair cost was around $3,900. - Luckily this failure happened on our community road and was able to pull into our driveway. Mechanic stated that if this happened on the highway or regular road, this could have caused a major incident and possibly a blown motor. - No, but complaints of similar issues have been reported via my online research. - Just by the mechanic I had my vehicle towed to. - There was no indication of an issue until the water pump failed.
