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: Except for a minor issue with cracked motor mounts, the 2007 MAZDA3 is a fantastic vehicle with a great reputation.

If you need to replace the motor mounts, first ask your dealer if they'll cover it -- the motor mounts were dealt with in a TSB & were recalled for some model years. Otherwise buy aftermarket motor mounts -- owners report this solves the problem. If you use the same OEM parts, they may just crack again.

MAZDA3 4-cyl

  • 32,500 miles


The contact owns a 2007 Mazda 3. on August 29, 2008, the power steering failed while making a right turn. The steering wheel became very difficult to turn and the vehicle had to be towed to the dealer. The dealer replaced the computer and the power steering pump. On March 27, 2009, the failure recurred while making a right turn. In addition, the power steering indicator illuminated. The vehicle was towed to the dealer again, where it has remained for the past two weeks. The dealer will replace the power steering parts for the second time; however, the contact does not feel comfortable driving the vehicle. He would like Mazda to purchase the vehicle back. The failure mileage was 32,500. Updated 05/07/09. The oxygen sensor was faulty. The dealer replaced the power steering pump and module assembly. The right front strut was replaced. Updated 05/07/09.

Oxygen sensor #2 had been cross-threaded into the exhaust manifold. Damage was done at the factory. Dealer refused to replace the part do to the fact that I had found the problem and not them.
