CarComplaints.com Notes: The 2010 Mazda CX-7 appears to share the same engine defects as the three previous model years: VVT/timing chain failure & turbo failure. The timing chain failure is especially bad with many cars requiring an engine replacement ($9,000+).
In 2011, Mazda began a "Special Service Program" that extended the warranty to 7 years/70,000 miles covering excessive timing chain noise — an early sign of timing chain failure. However coverage under the program requires perfect documentation of all required maintenance with other stipulations. Buyer beware.

About These NHTSA Complaints:
This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.

The turbo made a loud whining noise when the accelerator was pushed and you could not accelerate. Alot of white smoke was flowing from the exhaust. We immediately pulled over on our way home from out of town and called aaa to tow the car back to the service dealer in parkersburg wv. The vehicle only has approx. 19,000 miles on it with service records showing proper oil changes. The vehicle is under warranty and Mazda sounds like they don't want to cover this problem.
I was driving my Mazda when it started making this odd winding sound. At first it was not too loud but when I tried to speed up to get on the interstate, the sound got extremely loud. I brought it back home but barely made it up the hill to our street. I had the gas pedal to the floor but it had no power. I called road side assistance and they picked up my car promptly. When the dealership called me back, they reported that the engine had "gunk" in it. My husband changed the oil in the car but we never saved receipts for the oil, so we have no proof. I bought this car brand new in 2010. It only has a little over 32000 miles on it. The dealership is telling me that Mazda will not pay for the engine and it will cost $9000 to replace the engine. The car I drove prior to this was a Nissan Altima and we also did all the maintenance to this car. I drove the Altima for a little over 200,000 miles and it was still running well when I sold it. It makes no sense to me that this Mazda has a bad engine and it makes me even more mad that they are not going to replace the engine.
