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 owned a 2008 Mazda Mazda3. While driving approximately 40 mph, the contact noticed smoke from under the hood. The contact stopped the vehicle on the shoulder of the road.

Engine mounts failed. Noticed vibration in the cabin when the car was in drive. There was no noticed vibration when the car was idling. When the engine was in drive, with the hood popped, the engine was noticeably pitching forward and returning to it's default position when the gas was released. I checked recalls and there were none shown, but there were many complaints about this on the internet. Local mechanic also stated that this is a known.

Sitting in parking lot, engine and A/C on, then tried to pull out, power steering failed; had to wait one hour for car to cool before the steering came back on. The power steering pump failed, needs to be flushed, common problem with the Mazda 3's apparently. At least it did not happen on the road.

Shortly after purchasing a 2008 Mazda3 I 2.0L sedan, I began to feel a shake through the steering wheel and chassis while idling/driving. Dealer verified shake and per tsb due to an ongoing problem, replaced motor mounts. Car felt better but not completely free of engine shake and now appears to be getting worse. When the engine is started cold it shakes the entire car and when warm a suttle but noticeable shake is still felt though the steering wheel and chassis. After reading numerous posts on Mazda3 enthusiast websites, this appears to be a common and ongoing problem spanning several years.
