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.

My tire pressure light was on, so I pulled into a convenience store that has a combination inflation-pressure check machine. I checked one tire & had no issue. I checked/filled the next tire & didn't notice an issue immediately. I went on to the 3rd tire, and heard a pop, then a hiss. All air was leaving the tire. I then noticed the second tire was doing the same thing. According to the tire store, it was the valve stem pressure sensors. The tire store keeps the parts on hand because they are "seeing a lot" of this with the Mazda 3S, that it's a "design flaw" that has since been rectified on newer models. If I had only filled one tire & hadn't noticed the deflation, and then gotten on the highway, I could've been in a serious accident with my son in the car. This angers me: If it's so common of a problem, and it could cause accidents, why is there no recall??

After putting air in the tires, I drove approximately 2 miles down the road when the tire light came on. I drove approximately 1 more mile to my house. The tire went completely flat due to a broken valve stem.

Low tire pressure light came on. Found valve stem cracked and leaking air from its side. Has happened to two different valve stems. Southern car never exposed to salt. Valve stems look new. Tire store charges over $200 to replace each one.
