Starter location?

It is hiding in plain sight. If you remove the right hand splash shield from the engine the starter is behind it. If yours has an issue the first thing I would check is the ground connection that attaches at the starter stud itself, have seen a few that corroded there and gave the appearance of a failing starter. Cleaned the crud off and tightened things back up and it returned to normal. The shield traps dirt/water and causes issues. But it does protect it from direct water /snow splashes.
