NHTSA — Engine And Engine Cooling: Engine: Gasoline: Belts And Associated Pulleys Problems

CarComplaints.com Seal Of Avoid Like The Plague

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.

The contact owns a 2007 Mazda Cx-7. while driving 80 mph, the contact noticed that the air bag light illuminated on the instrument panel. Immediately following, the air conditioner compressor locked up and stopped the engine, which caused the serpentine belt to shred and the battery cable to melt. Through online research, the contact discovered that this was a common issue with her year, make, and model vehicle. The manufacturer offered to pay for 75% of the repair costs. The contact feels that this is a serious safety issue because a crash could have occurred. The current and failure mileages were 44,000.
