general problems of the 2000 Mazda 626

I have a 2000 Mazda 626 6 cylinder and for some reason it has started to just periodically cut off when at a stop, feels like if I hit my brakes a certain way, it will cut off. I have also heard 2 other people with same vehicle with like problem. Please advise if any other complaints on the above.

Actually I have lived with this problem since approx. Yr. 2003 one day I adjusted the lever for the brights or indicator and it felt as if it disengaged and was loose from then on. It seems that the light switch which connects with the indicator signals, intermittently the left headlight would go in and out (must have replace it three times until my husband realized it wasn't the bulb but the switch seemed to have broken loose)until recently the indicator switch would shut out the lights once I complete a turn and the switch re-adjust in place. This would happen occasionally with the brights on also. It would vary and you never know when it may happen. Now the switch for the brights are not working at all.

I own a 2000 Mazda 626 with only 90,000 miles. I have been stranded several times in this car and spent over $3000 parts and labor. I had to replace the catalytic converter, several sensors, master break cylinder, cv boots, and rack and pinion. Now I am having trouble with the transmission and the ac. The mechanic says I need to rebuild the trans and replace the ac compressor. This is another $3000 or more. I am very disappointed in this situation. I plead with you to take action on this. I have checked several web forums and found similar problems. Please, please make Mazda accountable for building such bad cars. Fyi, I am very, very diligent in general maintenance. Thanks for your time. Chris.
