I drive a 2015 Mazda 3 2.5 Touring automatic.

If if you are asking if there are any issues to avoid for that generation of Mazda, there are none that I know of except for the Red paint. I am not sure which red they used on this generation of the 3. If you want red it is worth further investigation.

Not sure why you are looking at one specific year since other years are similar. Be aware of the option choices for the various years and trim levels. It seems they shuffled the packages frequently. As an example the Touring was perfect for me but it excluded auto headlights which were included in later years.

I would also make make sure you drive cars with both engines. I am happy with the 2.5 and appreciate the extra power.
