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 2008 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.

The contact owns a 2008 Mazda 3. while driving approximately 50 mph, the vehicle veered out of control and the steering wheel became difficult to maneuver. The tire pressure monitor warning light illuminated. The contact discovered that the front passenger side tire valve stem failed and caused the tire to become deflated. The vehicle was not diagnosed, but the tire was replaced. The failure recurred with the front driver side tire, but the vehicle was not diagnosed nor repaired. The manufacturer was not notified of the failure. The failure mileage was 70,000.

The tire valve stem cracked while checking air pressure on one of the tires. After that the other stems looked like they were ready to fail. Had them all replaced.

On 4/19/2011 I was driving when my TPMS went off. I pulled into a gas station to put air in my tire. As I put the air pump to the valve, the valve simply disappeared and the tire went completely flat. I called aaa and took the car to a repair shop. They said the tire was perfectly fine and replaced it (without the TPMS). I eventually replaced the TPMS, which was not covered under warranty. On 4/25/2011, I was driving on the highway when the TPMS went off again. This time another tire had gone completely flat. When aaa arrived, the serviceman found the broken parts of the piece that holds the valve stem (and the TPMS) in the wheel. Without this piece, the valve was able to slip into the wheel (which is what had happened to me on 4/19). The pieces were completely corroded and had cracked in 3 places. The dealer replaced the TPMS (which was not, again, covered under warranty). Only after I insisted did they replace the remaining two valve stems which also had clear signs of cracking. This will most likely happen again in the future as the two metals of the valve stem and the piece holding it on begin to corrode. Updated IVOQ 06/28/11
