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.

An excess of white smoke emitted from exhaust upon acceleration after a brief period of idle. It was determined that a faulty turbo charger was to blame. So the car was in the shop for 7 days while they replaced the turbo. Several months later the car wouldn't start after sitting in a heated garage overnight. It sounded as though the cylinders weren't firing properly. Car was towed to mechanic who identified issue as fouled cylinder heads from prior failure of turbo. This time the entire engine was replaced. Again the car was in the shop for approximately seven days. Some months later an oppressive amount of road noise appeared at all speeds on all road surfaces. We were directed that the tires were to blame. After replacing all 4 tires at a cost of nearly $800 the sound persisted. Upon further inspection the technician found that the wheel speed sensors on the rear wheels had failed allowing water to seep in and rust rear wheel bearings. All four wheel bearings where replaced. Today the vehicle is again in for engine repair to replace the oxygen sensor and a dead battery. After owning the car for 18 months it is has been in the shop for a total of approximately 4 weeks.

I have a 2007 Mazda Cx-7. it is a very beautiful car but also has tons of problems. At 15000 miles it was leaking oil and they replace the engine gaskets. Then later was also leaking oil. Was told by the dealer that it was not. Took it to someone else who said it was leaking from the timing chain. Mazda resealed it. Since then my car doesn't shift properly going up and down hills. My air conditioner is hot and makes a funny sound. My car has loss of power and sound like a diesel. Overall I think that Mazda needs to step up and take care of the problems or they will not get many returning customers! something needs to be done! it was a 35000 dollar car!
