“My 2000 Mazda 626 began having problems a week after purchasing april 10, 2008! The car started having electrical problems which resulted in 3 batteries, 2 alternators, no AC or defrost could be run. Then the brakes were replaced twice within a 2 month period! All these problems resulted in me almost being killed from an automobile accident! This happened june 8, 2009 which was a monday approx. 4 pm. The airbags never deployed, and my head hit the steering wheel. Windshield shattered all over my hand resulting in severe lacerations! This car needs looked at asap!!!! Please help”

“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. …”

“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. …”
