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.

We have had a 2005 Mazda 3 hatchback for little over a year and a half. We bought the car with 30,000 miles and have added around 26,000 more. Regularly keeping it serviced on our own Accord with out taking it in to the dealership. The engine began making a knocking sound in the engine that seemed to be getting worse with time. After about a week we decided to take the car into the dealership. Their investigation found that there were metal shavings in the oil and that engine was failing (in 2005 car with only 56,000 miles on it) and that it would cost 7000$ for a new engine. We believed this to be a faulty engine rather than owner liability. We tried to contact Mazda customer service. They were rude and belligerent. When asked to speak to the supervisor, she was also rude and unresponsive. When asked to speak to someone else at the company above her, she denied us the right to complain to anyone further. Since then, we have had to park the car until enough money can be saved to fix an engine that in our eyes is defective, and further deal with a company that is not very helpful to it's customers.

My Mazda3 2005 has had an A/C compressor problem. This expensive part has been replaced 4 times to no avail. It fails again every time, and Mazda insists there is no problem with the part.

While driving on the highway, on a 2005 Mazda 3S with 39,000 miles, about 30-35 mph had to slow down due to the car in front of me, upon acceleration to regain desired speed the car stalled, lost all steering and braking system, almost getting rear ended. The check engine and battery light came on, indicating that the car had lost power, by then I barely had enough momentum to pull into the median and turn on my hazards lights. Took a few tries to get the car back on. This is a serious safety issue, due to the fact that all steering and braking system is lost when this happens. Mazda dealership service dept is looking at the issue.
