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.

My CX-7 has less than 64000 miles and as I am planning to retire in December, I was not planning on getting a new car. The car just stopped running in the middle of traffic on a busy highway. I have had it repaired multiple times, brakes, 2 batteries, regular maintenance, oil changes, fuses for multiple headlight replacements, internal thermometer and multiple visits for the check engine light and noises from the engine. Before it died I was told I needed motor mounts and sway bar links replaced along with the battery and thermometer which would have cost $1100. Thank goodness I did not have all of those repairs done at once since it died a week later!
Since I had just had work done at the dealer when my car died I had it towed back to them, thinking it was something they missed. To my shock and dismay they informed me that the timing went and they recommend getting a new engine. They said 90% of the time when this happens and the owner chooses to get the timing repaired they end up still needing a new engine. I was quoted at least $9000 for a new engine. I cannot afford that so I had it towed to my home where it now sits.
I cannot believe a car with that low mileage needs a new engine! I have poured thousands of dollars into this vehicle and was hoping to have it for many more years into my retirement.
