We own a 2000 mazda millenia that stalls at about 50 mph and has had this problem since we bought the car. we have taken the car in for servicing numerous times, but have not been able to get this fixed. the car has several other problems such as: keyless entry does not work, heated seats do not work, air conditioner does not work; however, none of these pose a safety problem like the stalling. the engine light remains on even after numerous attempts by the dealership service department to repair this problem. *jb
