CarComplaints.com 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.

CX-7 2.3L

  • Automatic transmission
  • 11,700 miles

The A/C never fully cools car down, and a few times throughout the day it starts blowing hot air. It blow so hot at time that it is more comfortable to roll down the window even when it is 105 degrees outside! I have taken it into the Mazda dealer twice and both times they put a thermometer in the vent and tell me it is working normally, but don't know why it blows hot sometimes. I have read enough other complaints about Mazda CX-7 A/C problems that I am sure the dealer is aware that there is a legitimate problem, but they just try to make me feel stupid and tell me I am not going through the proper cool down procedures when I first get in the hot car, like I should try turning on the A/C and roll down my windows until the hot air gets out. DUH! This doesn't help 20 minutes later when the car is luke warm at best and then starts blowing hot air.
