I was driving to a local auto service garage, and upon crossing some rail road tracks, the engine developed a loud clicking noise, it lost significant power output, but I was still able to drive it slowly to across the street from the garage. Then the engine cuts out and the check engine light came on, along with the battery indicator light on the dash board.

The car repair shop folks told me the engine does not start and there is evidence of valve and piston damage, and I will need to replace the engine. Likely cause is the timing chain jumped time (skipped gears). Parts and labor is estimated at $7400. Before this happened, even a year ago, I started noticing the engine making louder ticking sounds than it used to, and I believe this is a symptom of the timing chain part of the engine starting to fail. If I had addressed that issue (probably a $1500 repair), then perhaps the engine would not have self-destructed.

Car stopped on the road while driving and I am getting different diagnosis. Some are saying it is turbo charger and my mechanic is saying the engine needs to be replaced. This is awful and very disappointing. It seems a lot of people are having same issue. Mazda, please do something. I am very angry and disappointed

considering there was very little warranty on this car the repair bill and parts cost is terrible, not to mention I was in traffic on a very busy street and my dealership closed right after i bought this car. i had to take it to the dealership an hour and a half away.

Luckily my power train warranty covered this problem. But in doing research online I found this is a VERY COMMON problem on the Mazda Cx-7. Very sad that a car that's barely four years old would need a whole new engine already! It was not a cheap car!
