“My 2000 Mazda 626 ls overheated on june 16, 2006. The o/d off light has been flashing when on the road for more than an hour since the fall of 2005.

“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. …”

I was told that the car was okay the motor mounts were fine and that the noise was from a bottle of aspirin in the glove box. The noise continued and other shops continued to inform me that my motor mounts were bad. I was again informed by the repair shop that the car was fine. The vehicle now has 140,000 miles on it and the motor mounts, sway link bar and struts are all shot to heck. …”
