I have no major gripes with my Mazda 3, except the tires. The tires are rather thin, and I tend to get flats more often than other drivers. Besides that, I have had zero mechanical issues with the car since 2011.

I loved my Mazda 3. It didn't cost me an arm and a leg, and the I drove the car trouble free for seven years. The only thing done on it were oil changes and breaks. Oh... I had tires put on it last year. The car past inspection every year with flying colors. It was the most reliable car I've ever owned.
