“In august 2001, I purchased a Mazda 626. In may 2003, I started to experience major problems with the car. At 23,000 miles, the following had to be replaced: transmission assembly, thermostat and radiator sub-tank. At 31,000 miles, my car was in the shop for 11 days in order to replace the following: mass air flow sensor, fuel pump and fuel pressure regulator, valve idle air control, thermostat gasket, and the throttle body gasket. My car is nearing the end of its 3 year/36,000 warranty and I am frightened about how much future repairs will cost, as well as the overall safety of the car.”
