Battery

This. My battery made it just under three years here in FL. I do alot of driving too.

 

Subaru's had them also. I got about 6 or 7 out of the Panasonic in my 07 impreza.

 

So my 2010 has 16K miles now, but it is also 7 years old. It seems to crank over just fine for now. Should I still think about replacing it this summer?

 

Perhaps. Problem in our area is the cold weather even with low mileage

 

Batteries like to be used.
They dont like heat
They dont like extreme cold unless fully charged

My old test was keep headlight on for an hour and try to start. If it don't start then you need a new battery.

I have left parking lights on for 9 hours on my 99 taco and it started right up.

 

Sounds like ill be replacing before winter!
