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.

problem #1

May 052004

MAZDA3 4-cyl

  • Manual transmission
  • 200 miles
After 200 miles I noticed an excessive amount of brake dust accumulating on the rear wheels. The rear brake rotor surfaces are worn extremely uneven with multiple grooves. This type and amount of wear is what I would expect after 10,000 miles not 200. The front brake rotors are hardly worn at all and still exhibit the original machined surface. I found that Mazda has a new brake pad for the rear brakes (P/N: bpyk-26-48Z) but no technical service bulletin has been issued.
