Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

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.

As I was driving, the timing chain broke and imploded into the engine, damaging the engine which now needs replacement. This appears to be a common occurrence with this vehicle.

problem #1

CX-7 4-cyl

  • 55,882 miles
Started smelling strong burning rubber odor emanating through vents of car while in operation, exited highway upon seeing white smoke fuming from under hood. Loss control of steering and vehicle shut off and would not crank again. Mechanic determined ac compressor has seized and serpentine belt was snapped due to friction from pulleys. If I had stayed on freeway instead of exiting, with the lost of steering I surely would have posed a danger to myself as well as others on the road. This complaint is one of numerous thousands that have been filed on behalf of Mazda and its Cx-7 model. There should be a recall issued for the ac compressor before it causes serious injury and/or fatality.
