Notes: The 2009 Mazda CX-7 appears to share the same engine & A/C defects as the two previous model years: VVT/timing chain failure, turbo failure, & the A/C compressor clutch seizing. 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 turbocharger oil leaks & 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.
