CarComplaints.com Notes: The 2007 Mazda CX-7 has numerous reports filed with the NHTSA about engine & A/C problems.
Owners report problems with the 2007 CX-7's Variable Valve Timing (VVT) & timing chain failing, causing major damage to the engine — Mazda uses an interference design so typically the valves are bent & the entire engine needs to be replaced. Mazda dealers typically quote $9,000 for an engine replacement.
There is also a trend of the turbo failing at low mileage.
Finally for the 2007 CX-7 there is a clear pattern of A/C compressor failure at relatively low mileage. Owners report smoke & occasionally the serpentine belt catches fire when the A/C compressor clutch seizes while driving. Mazda extended the A/C warranty to 60,000 miles, however many owners report their A/C compressor failed very soon after the 60k mark.
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.

I am having issues with my engine light on and my car having problems with a loud noise coming from the engine as well as sometimes shaking while stop in a light for a while.
On the 4th of July my family and I were driving to westchester from manhattan. We had a full tank of gas, recent oil change and new car battery. The car is always maintained and it has never given us any trouble. During our drive we noticed something was wrong. The the car started to feel hot, but we weren't too sure if it's just hot out or if there was something wrong, because the ac was on. We pulled over and turned the car off. We checked the coolant and saw that we had oil. We opened the trunk, felt around to see if it was hot and to see if we smell anything. It seemed fine. As soon as we drove off, not 2 minutes in, when driver said the gas petal felt weird, it dropped from 50 to 30 to 20mph and we heard a light drilling noise. As soon as we stepped out of the car, it was in flames. Our family could have died. Https://www.facebook.com/valhallafd/posts/1548408978544577
As I was driving, the timing chain broke and imploded into the engine, damaging the engine which now needs replacement. This appears to be a common occurrence with this vehicle.
Started smelling strong burning rubber odor emanating through vents of car while in operation, exited highway upon seeing white smoke fuming from under hood. Loss control of steering and vehicle shut off and would not crank again. Mechanic determined ac compressor has seized and serpentine belt was snapped due to friction from pulleys. If I had stayed on freeway instead of exiting, with the lost of steering I surely would have posed a danger to myself as well as others on the road. This complaint is one of numerous thousands that have been filed on behalf of Mazda and its Cx-7 model. There should be a recall issued for the ac compressor before it causes serious injury and/or fatality.
