Notes: The 2008 Mazda CX-7 has numerous reports filed with the NHTSA about engine & A/C problems, continuing these defect trends from the 2007 model year.

Owners report problems with the 2008 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 2008 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.

Mazda issued a warranty extension on the A/C compressor because of a known problem. My compressor broke after this extension. It created a safety concern as the clutch broke off of the compressor cause sparks to fly from the loose rubbing metal. Sparks were not caused from electric arc. When the clutch originally seized the engine / compressor began to smoke. I turned off the ac and drove home. Upon driving the car to to the repair shop with the ac off, the clutch separated and began sparking. This clutch could have separated and shot like a projectile. Ac compressor broke while on highway. I have the old part should you like to see it.

The driver's seat under welding which attaches the chair to the body of the car, under the seat, has become detached for no known reason. The front end of the driver's seat unit is no longer attached to the frame of the car yet the back end of the seat is still attached by the motor controls to the power seat. The driver's seat actually rocks back like a rocking chair lifting & moving the seat and backrest as one unit. The broken weld is actually visible when looking under the driver's seat. The motor to the power seat has been functioning but is deteriorating. The seatbelt cannot protect me from this defective seat, if I were rear-ended it would be likely that I, the driver, would be flung backwards into the back seat which could fatally injure one of my children.

Without warning the cabin of my Mazda Cx-7 filled with smoke and the powersteering went out. Apparently faulty ac compressor burned belts and knocked out powersteering. Mazda replaced compressor with new revised compressor.

My car is a 2008 Mazda Cx-7 and this summer I began to use the ac which never seems to cool off my car. It blow cold air but not very cold and I have to keep it at level 4 and push the other button that makes it blow harder. Which I think is the circulation button. I should not have to keep it on full blast and with the ac button and the one next to it depressed all the time to cool my car off. I don't think it is running correctly.
