“We were on a city road uphill and driving to a friends home. Our Mazda CX-9 grand touring made a rattling noise, released a lot of white smoke, and lost acceleration. I immediately pulled the car on the shoulder and a by passer stopped his car on opposite shoulder and analyzed the situation and shouted move your family out and move from the car since its on fire underneath. We immediately moved out and by passer called 911. All the time while we waited and fire department arrived the car was dripping fire.”

“My wife took our 2014 Mazda CX-9 to liberty Mazda for a check engine light that came on the evening before she already and an appointment for another issue. She asked them to check the light as well. After their findings they told sue the car had a catastrophic water pump engine failure. This water pump is located inside the timing chain cover and leaks coolant in to the engine. At this point we were handed over to a sales rep. Who informed us this was a foolish design with the water pump located in the powertrain behind the timing chain cover. …”

“I noticed a rough noise when I started the 2014 Mazda CX-9. I chose to ignore it thinking it was because of the cold weather. Got to the highway on the way home to kansas city from columbus, oh. Several miles later when filling gas, I noticed a weird smell like that of a burning rubber or coolant. The car got me home same but I noticed slight smoking from the engine when I got home.took it to the mechanic and he advised it was the water pump. He didnt have the right tools to replace it so I took it to a Mazda dealership who advied getting a new engine. …”

“Noticed burning smell coming from underside of vehicle and oil-like substance on floor of garage after driving. Took to the dealer and was informed that the transfer case failed and was leaking fluid on exhaust system. Research indicates this is a known design issue in multiple year models of Mazda vehicles and I feel due to the significant fire risk of oil/lubricant dripping onto the exhaust system, this should be subject to a recall.”

“- 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.”
