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.

The contact owns a 2007 Mazda 3. the contact stated that the rear driver side tire deflated. The contact changed the tire with a spare tire and indicated that the jack was defective. Upon changing the tire, the metal frame fractured as well as the rocker panel without warning. A tire repair shop replaced the tire. The manufacturer was notified of the failure and provided no remedy. The VIN and failure mileage were not available. MA 08/10/15

I was notified by the Mazda dealership that an integral hydraulic engine mount was cracking and needed replacement. I was just past my car's warranty so I drove on it since they said it was safe. On November 8th 2013 during a service I was told the integral mount was about to break and needed immediate replacement. They said if the mount had broken while driving it could cause an accident, not to mention destroy the motor. I had them replace it but had to pay out of pocket since it was past warranty and not a recall. I researched online and found numerous complaints from other owners of the same series car and within adjacent years of the same motor mount cracking and needing replacement under 50,000 miles. Some complained about having to replace the replacement later after putting some more mileage on it. This is an obviously inherently defective part that should be recalled. Please look into this and force Mazda to recall this defect as it is a danger to public safety if one were to break while driving. Thank you so much for your time and service.

On Feb 13, 09 I had the engine mount on my Mazda 3 hatchback replaced because it was leaking. Today I was informed by the Mazda technician that the same engine mount was leaking again and need to be replaced. His comment was that the engine was too heavy and speed vibration causes the mount to fail.

I have a complaint that could be very dangerous to others. I know to check my blind spot, but even when you turn to look over your shoulder (either way), the back panel between the back glass and the door is in the way. I have at least 3 times now, almost switched lanes into another vehicle because it wasn't visible. I looked in the side and rearview mirrors, as well, but I never saw the other vehicle. A friend of mine, as well as other 3 owners, also has the same problem with their Mazda 3.
