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: So far Mazda seems to have fixed the serious engine & A/C defects that plagued the 2007-2010 CX-7s. We're giving it a tentative "Good" rating for now.

The head lights and tail lights have been replaced over three times in least than two years. The condensation on the covers makes it difficult seeing where one is driving. This I believe is a safety issue. This condensation has also caused my radio to lose its sound. The battery will not start if it rains or its cold.

Purchased vehicle on 2/27/2011. 1) Dec 27 2011 replaced drivers headlamp. 2) 4/18/12 battery issue. Car would need jump starts randomly 3) 8/18/12 passenger headlamp replaced 4) 11/5/12 battery replaced 5) 12/21/12 drivers headlamp replaced 6) 7/1/13 drivers headlamp replaced. Went to 2 different dealers to replace items. Both dealers assured me there is nothing wrong with electrical and it was just one of those things. Unfortunately 4 headlamps and a battery within 2 years of owning the vehicle is just right.
