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.

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.

Purchased 4 new dunlop tires 205/50R17 for 2007 Mazda 3 2.3L at odometer reading 39484. At 70115 miles, 3 of the 4 tires show separation of tread on the insides walls of both front tires and right rear this a design flaw of the dunlop tire manufacturer or is the issue with Mazda design of wheel placement?

Our 2007 Mazda S 2.3L 5 door sedan bought new came with Goodyear Eagle rsa 205/50R17 tires. We maintain this car well and regularly. March/April 2008 with 28,000 miles we experienced a tire failure. Thread separation, progressive hard flapping noise, and air pressure loss. Took it to Goodyear tire and we were told the tire failed, thread separation, and another tire too had same problem. We bought two replacement new tires. Sept 2010 with 53,000 miles the other two original tires are failing same manner. Progressive loud flapping noise and pressure loss. The tires are worn but have plenty of thread depth, and we were told at Goodyear a month ago they did not need replacement yet when we asked. It seems that these tires in this vehicle are failing rather than wearing out. So, I'm now off to Goodyear to buy 2 new tires again!

I have been getting my car regularly maintenanced (and tired rotated and balanced) every six months and I have all the receipts to prove this. Dates as follows: November 14, 2007, March 6, 2008, August 25, 2008, April 9, 2009 and Sept 4, 2009. I was informed that my tires were ┐cuppling┐ and that I need all 4 tires now as well as a 4 wheel alignment. There are toyo tires and I have one 34,000 miles on them. I was hearing rattling sound coming from the console, dashboard and passenger side door while I drive. I was told it was wires lose and they fixed it....but in fact they did not. I have also had problems with the power-train (reflashing) and battery died before the car was even 6 months old. They changed the battery and supposely fixed the power train.

I bought a Mazda 3, 2.3L which had the original manufacture tires which are Goodyear rs a P205/50R17 dot V4H4 4mbr 2906 V2589 which gave me a scare since while I was driving. A piece of tread from my front right came off.took the car to have them replace. They did a diagnostic to see id the car was off balance, but everything was fine. Also the tire shown great deal of damage specially on the inside of it. I am concern if someone else have the same problem with this tires. Since in the shop they couldn't find any wrong with my car regarding the wearing of this. 3 of the 4 tires showed significant damage in the inside of it, you can see the metal.
