The failure mileage was 93,000. Mazda is not owning up to any of it. In a matter of seconds my vehicle slowed down and almost caused an accident. The contact took the vehicle to a dealer for a diagnostic test. I will continue to spread the word of this horrific issue with this vehicle model.
This should be a recall since is faulty parts and there are hundreds of customers complaining of the same issues.

They said because the turbo runs very hot, it burns up the oil quickly. No mention of was made. They informed me the cars timing belt needed to be replaced and there was sludge on the engine.

It was replaced and the engine light came on again the next day. The vvt actuator failed and was replaced by dealer penkhus Mazda under warranty in 2009, but the chain was not replaced. The dealership told me I needed the timing chain and assorted peripherals replaced. My home is between 175 and 225 miles from the nearest dealer. The noise was so unexpected and unrecognizable that the shock I experienced when I heard it caused me to tense up and veer off to the right. God forbid that my car turns off and I have and accident, since car gives no warning. The air bag light is on and was on when I took it in.
