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.

CarComplaints.com 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.

Hard knocking noise occurs when attempting to turn the vehicle. Dealership has made multiple failed repair attempts to fix the vehicle (a motor mount, rear sway bar bushings, front strut bar bushings, front sway bar, stabilizer plate, control rod, upper strut bearing and mount) as drivability and handling issues have become worse. The dealership recently determined that the vehicle has a bent lower A-arm which is of no fault to external influence. As the vehicle is now out of warranty the manufacturer is refusing to fix the vehicle. The defect in the lower A-arm is as a result of a failure in material. The front end geometry is now severely out phase by 30 degrees (per the dealership) which can cause undue stress to the lower ball joint causing premature breakage. The result of the lower A-arm separating from the spindle can cause an accident. The vehicle needs a new A-arm and possibly other related components. Tw*

2007 Mazda 3 excessive premature tire wear. At 30,000 miles I see that the front tires are worn to the point of steel band visible and sticking out. Inspection at 25,000 miles dealer said there was wear but not critical. The tread is separating and I am replacing tires immediately. I have learned that front suspension has excessive negative camber causing this.

I have had the dealer replace front end parts 2 times. First the front hub bearings. Then they had to replace the intermediate shaft also part of the front end. The car is 2007 with 37,000 miles. I have other cars with over 100,000 miles and never had to replace any of these parts.
