I have read quite a lot of posts on and here and on lots of other sites that include Mazda's that are jerky mainly at low speeds when coming to a stop or accelerating. My car does exactly this. It has been on the diagnostics 3 times and has the radiator brackets changed but it still does it. I have been told by Mazda Australia that this a normal concern. I am pretty annoyed about it all. This issue has been going on for over a year now and I can't understand how a car jerking is normal. I have never driven another automatic car that does this. In this day an age surely cars shouldn't do this. It is not normal so how can they get away with it?
