Alternator @ 70K Km, C$450.
Radiator @ 85K Km, C$600.
Rear right door lock, C$185.
Muffler kept breaking after every 25K Km, at least C$ 150 each time.
Ignition broke after 125K km. Can you believe it? C$300.
Wiper motor failed in the middle of a heavy rain on a highway at 116K Km, C$250.
I had to change the front rotors every 60K km, C$700 each time.
Gas Tank leaked at 124K km, C$400.
Transmission failed @ 161K km, C$2000.
Everything started breaking right after the warranty was over and cost me a fortune every time. The dealer says parts for Mazda are always expensive, about 2-3 times of any competitor.
I have now bought a Chevy Malibu and hope it gives some relief to my pocket, and a reliable/affordable ride to me.
In short, all parts of all Mazda cars are ridiculously expensive.
I have a 1990 929 S and its still running great. The car will just not stop running.
Seems pretty unlucky that your particular Mazda happened to break down between 70Km - 160Km!!
They are very reliable and yes the costs of repairs are expensive compared to others, but if in good care, shounldn't be in need of so many repais.
