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.

problem #4

  • 58,000 miles


On my 30 mile drive home from work, I briefly smelt something burning. Later on that drive, I realized that my A/C did not seem to be blowing cold. My A/C has always taken a while to cool the car down, but it wasn't even cool after my 30 mile drive home. When I confirmed that the A/C was not blowing cold at all, on my drive to work the following day, I took my car to a repair shop to have the A/C checked. That is when I was told my A/C compressor had "locked up" for some unknown reason, and needed to be replaced. I took my car to the Mazda dealership the following business day and they confirmed the same. Mazda could not provide an explanation for why this happened at 58,000 miles. The compressor is still not repaired at this time because the Mazda dealership will not warranty their repairs.
