My 2004 Mazda 3 often stalls while I'm driving on the freeway, I took it to dealer and they are not able to re-create the problem and they won't fix it. I think Mazda corporation has to do something about it cause it is a known issue to many Mazda 3 out there and it always scare me whenever my car stalls on the freeway as it is very dangerous.
