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.

2007 Mazda 3 gas cap vehicle failed state car inspection. Parts department at dealerships having a problem keeping part in stock. Have been told by dealership that Mazda updated gas cap in end of 2007 knowing that there was a defect.. talked to service dept, every 2007 Mazda 3 that is now going through it's first inspection has failed. Could cause engine problems in future. Mazda will not replace gap, only sell new ones. Mazda has not notified owners of problems.
