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 2010 Mazda CX-7 appears to share the same engine defects as the three previous model years: VVT/timing chain failure & turbo failure. The timing chain failure is especially bad with many cars requiring an engine replacement ($9,000+).

In 2011, Mazda began a "Special Service Program" that extended the warranty to 7 years/70,000 miles covering 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.

I purchased the 2010 Mazda CX7 vehicle about nine months ago. I frequently do not drive the vehicle because I feel it is unsafe under many conditions. The dash lights are inadequate and make it almost impossible to know how fast you are traveling day or night. I am afraid I will be ticketed for traveling too slow or too fast when the instrument panel is so poorly lighted. I have looked at other 2010 and 2011 models, and they are all the same, poorly lighted. I recently spoke to someone with another model who had the same complaint. I feel that it is unsafe and should be recalled. I have no other complaints about the vehicle at this time.
