Faults:
Since I acquired my vehicle I have had very few problems that are not expected with mileage on any vehicle.
At approximately 100,000 miles the water pump went out. I had a Mazda dealership repair this due to the extent of work, and lack of tools and space.
At approximately 110,000 miles the oil pressure-sending unit went out causing the vehicle to dump all four and a half quarts of oil on the freeway. This was also a Mazda dealership repaired item, due again to a lack of tools and space.
At approximately 125,000 mile I had to replace both drive axles. I went to Auto Zone to buy this item for the fact that Mazda wanted $500 for each axle, and Auto Zone only wanted $150 with a lifetime warranty. I took this to a small mechanics shop to replace this item costing me only $65 an axle. I also had to replace the oxygen sensors at this time. This was very expensive although I did it myself. I spent approximately $300 on just the sensors alone, not purchased from Mazda.
At approximately 135,000 miles the thermostat ceased to open causing severe engine overheating. This was not only something that needs to regularly be replaced. I found that the thermostat I removed from my vehicle was the original from Mazda. This I replaced myself with minimal effort and cost.
