CarComplaints.com 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.

Bought my CX-7 brand new, in fact the first new vehicle I ever bought. At approximately 75,000 mile I had my first fuel injector fail. After my mechanic opened the engine he informed me he had never seen a engine more gunked up with carbon build up. He had to meticulously chisel off the build up and clean the valves before replacing the injector and informed me that all of the other injectors would likely have the same problem.
Sure enough, within a few months two other injectors failed. To make matters worse the engine developed a loud ticking sound from the belt tensioner likely due to the engine running so poorly from the injector problems.
I no longer own this vehicle and recommend car buyers to steer away from Mazda CX-7's unless visiting auto repair shops is a hobby!!!
