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.

problem #2

Oct 202012


  • 44,000 miles


We were driving 65mph on the I-15 freeway in centerville Utah and the sunroof exploded with tremendous force, the sunroof was closed and we were not near an over pass, glass shot into the car and luckily no one was injured, if there would have been some one in the back seat they would have been blasted with glass. There was broken glass from the front floor area to the rear cargo area with most of it in the back seat. After inspection it was clear that the glass that remained was lifted upward away from the roof. We searched on the web and this has happened to a good many people with the same description that the glass exploded outward with many pieces blasted into the car. There was no sign of an object hitting the sun roof.

The contact owns a 2007 Mazda CX7. The edge of the driver-side door is curved and sharp; therefore when attempting to enter the vehicle he sustained a laceration. Also the visor on top of the sun roof fractured. The tires tread began wearing abnormally starting at 26,000 miles. The dealer nor the manufacturer have been notified of the failure. The failure mileage 26,000.
