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. 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.

Airbag safety sensors failed in my 2007 Mazda Cx-7. airbag light started coming on about 2 weeks before took vehicle to dealership. Called dealership ad was told it could be just baggage on passenger side seat and to come in if persists. It persisted and took vehicle in to be inspected. Technicians said sensors underneath front seats failed and needed to be recalibrated. Authorized the repair drivers side seat was recalibrated but passenger side could not. Airbag safety sensors not covered by extended warranty offered by Mazda and Mazda will not fix safety issue because vehicle no longer under manufacturers warranty. Technicians could not give me a reason why the sensors failed and why Mazda does not cover safety items that can save a life.

Since I bought my Mazda Cx-7 I have seen intermittent passenger air bag on and off. Now at 89,000 miles the driver air bag came on two weeks ago and went off but have not seen it come back on since then.

At about 55,000 miles and only 3 years of usage, my vehicle started making a terrible racket and smell. I opened the hood to see it was a the clutch of the air compressor that had locked up and caused big problems with the belt. Trying to drive the vehicle to get repaired only made the issue worse. I got a brand new air compressor installed and the noise is now gone and the ac is working fine. (after paying approximately $700) however, the air bag light just started flashing and then staying on and it's only a week since the ac repair. I am worried about the safety of the vehicle and if there is a connection between the two issues. I am reading about all sorts of complaints with both issues and I have read a technical service bulletin about the airbags. A recall needs to be completed very quickly before many owners get seriously injured due to these rampant defects with the vehicle.

Passenger airbag light come on as being off when my wife is seated on passenger seat. Dealer fixed it 5 times and works better then before, but still occasionally comes on while driving almost randomly on/off. My wife is petite but weights 105lbs or so. The light should not come on as being off for this weight.

My 2007 Mazda CX7 is equipped with passenger airbag that shuts off when there is no passenger. Most of the time (60% or so) when I am driving with my wife in passenger seat, the passenger airbag off indicator is illuminated. Same with when my wife is driving and I on passenger seat.
