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.

The issue has been ongoing, but originally started in the summer of 2008 (car had roughly about 42,000 or so miles on it). Initially the car would increase the RPM up to 7000R in 5th gear (going to 6th) and then decrease causing it to do a hard jerk (someone else described it as being rear ended and that's exactly what it feels like). I took my car to the Mazda dealership in marlow heights, md (while it was still under warranty) and the service person and I went for a drive (I was driving) he told me that he didn't notice anything off about it so I went back home. Fast forward to 2013 (the problem persisted through the entire time) when I took the car the arlington Mazda dealership. This is where they did a test drive on it and came to the conclusion that my car's transmission is going bad (the car had about 49,604 or so miles on it). To date, the vehicle (which now has 58,360 miles on it) has trouble picking up speed is extremely laggy and in 5th to 6th gear will pull a hard jerk before it catches up with itself. I agree with the other owners who have this problem. Mazda needs to recall and replace the transmission because there's clearly a safety issue. After all, if another vehicle is following too closely behind the vehicle(s) having this issue they are going to undoubtedly be involved in a serious collision and there probably will be a fatality. Please note: I included the mileage the car has so that those considering purchasing this car will know they may not have long to enjoy it before they have a really dangerous and expensive problem on their hands.

MAZDA6 6-cyl

  • 82,000 miles
When accelerating or climbing enough to invoke a downshift, the transmission occasionally slips or disengages causing very high RPM, followed by a sudden downshift and very hard jerk. It almost feels like being hit from behind. This failure poses an extreme rear end collision hazard. Mazda has issued tsb 05-016/06 to deal with this problem but my dealer informed me that Mazda now recommends a complete transmission change in lieu of a valve body change recommended by the tsb. This transmission should be recalled, it's unsafe.
