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.

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.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Prior to this date, which lead up to the last incident, upon getting the first few oil changes, at a dealership where I purchased the car, the engine began to sound like a truck (oil used was not synthetic and I were scheduled to come back in 5-months). When I inquired about it, I was told, "that was the way it was supposed to sound". after that comment, I changed to another dealership for service. The knocking continued, to this day, still. Over the years, the system lights would come on periodically (passenger air bag, check engine light and tire sensor) and the cooling fans would run after you turned the car off. Most times, they would reset themselves. Moving along, recently on 07/15/14, I was returning home for the evening and the car shut down on me. The steering control was hard but I kept it from crashing the wall on Lincoln dr. As I flagged the traffic to proceed, I was able to start the car only to advance to the end of the drive. Before I reached home, the car shut down 5-times. Finally reaching home it sat until I were able to get it to another dealer, closer to home. How about, the engine is shot, the radiator had a leek, I knew nothing about and the dealer says, "it will not start, now". I drove it to the dealer. Oil light was on and smelling as if I burned something, while it knocked. Check engine light and passenger air bag light were on when it cut-off, as I pulled into their driveway. I restarted the car found a parking space. Once the ignition shutdown, the cooling fans came on. Dilemma, I leased the car new in 2007. I bought it, with present car payments until 2016, in 2010. The dealer requests the engine and radiator to be replaced. There is no warranty, especially after 100,000 miles and I have scrap on my hands. Where does one go from here as Mazda used to be reputable? the engine shouldn't have any problems before 200,000 miles.
The contact owns a 2007 Mazda CX7. The contact stated that smoke was emitting from the vents. The contact was able to merge to the side of the road and turn off the vehicle. The vehicle was towed to a dealer for inspection and they stated that the air compressor needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 139,000.
