My check engine light came on. Thought it was the oil needing to be changed. Oil was extra dark and muggy. Also notice antifreeze low. Fill up antifreeze and change oil. 2 wks later antifreeze back down low. Check engine still on. Got it diagnosed with auto scanner and says camshaft sensor. Went to autoshop, mechanic says it's not cramshaft sensor but water tank leak in engine which was picked up by camshaft sensor. I have yet to find out what else is wrong or if my engine needs to be replaced. For sure the water tank needs replacement. I read from others of their car over heating or completely stopped working. I fear this because I have 3 kids and on weekends I drive on the highway for about an hour to get to my destination. This is something dangerous because I don't want to get rear ended or hurt if my car suddenly gives out during heavy traffic.

I was driving into the highway and my vehicle just shut off. I was in the car with my children and I was scared that we were going to be rear ended. I had my mechanic look at the car and he advised me that the water pump leaked and the coolant leaked into the oil. I-??m having another mechanic provide me with an estimate of how much the repair is going to cost. After the car shut off and I tried to turn it in again the batter, engine and oils light went off and I had the car towed to the local mechanic.

I've had my Mazda for only 3 years. I was driving up the hill towards my house to park my car and it just quit working. It shut off and now it will not start. Now I'm stuck paying $400 a month for a car that doesn't even work. It's very disappointing. I think this car should be recalled.

While driving my 2015 Mazda Cx-9 on a very busy interstate, the check engine light appeared on the driver panel. I was traveling with my very young children, ages 4 and 20 months. Approximately 10 miles later, I started hearing a rattling sound under the hood. Shortly thereafter, my car stalled out as I entered my subdivision. My husband had to push the car to our driveway. I called aaa that same day and had the car towed to the dealership that services the vehicle. I was told that the water pump needed to be replaced and was quoted a price to fix the issue. Later, I was told that after further inspection by the dealership that the coolant mixed with fluids and the engine needed to be replaced. I was quoted over $7000 to complete this work. During the course of my research, I have learned that a lot of Mazda customers who have this model vehicle experience this issue quite frequently. I called Mazda customer care and was told that Mazda is not electing to take responsibility for this issue. I was fortunate that I was able to arrive to my subdivision without injuring my children or self, but this is a safety issue that could result in the loss of lives if not corrected immediately.

I purchased the car new on September 18,2015. Having the car for 3 months I have been at the service department 3 times. I got home the first day and the belt was not registering and was making noise when I had it on. The last 2 times I continue to hear noise coming from the car. The noise is heard from underneath and it has to be driven for significant amount of minutes before the noise goes away. I recorded the noise on November 28,2015 and called the dealer very upset because its a problem that's not being addressed and fixed. I dropped the car off on Monday November 30,2015 and was told yesterday December 1,2015 that they dont see the problem.this is a new car and I never test driven before buying. I need help. I have the recording but I cant attach it on here.
