The Cx9 was taken to normal maintenance and there was not any report in regards to engine performance, after several driving around 200 miles issue came on, the temperature sensor was turning on and we had to move aside on the road, there was a big water leak on engine, oil was mixed with the coolant and water, engine is damaged on cylinder and cylinder head , water pump, no way the Dealer can respond on this, as for example Booster issue was claimed and no response from the dealer. Never ever will buy a Mazda car in my life
