My car has been making a groaning noise when I turn, especially a hard turn toward the left. I did a little research and tried adding power steering fluid (which was, indeed, very low). It seemed to do the trick, but now it keeps happening.
I'm planning to take it in but I'm wondering what could be the problem other than a leaking power steering fluid reservoir, because I see no fluid and the level isn't bad because I've added fluid now at least three times. It's a little lower each time, but not rock bottom.
Any advice would be appreciated. The sound also seems to be happening faster each time (so after I add a little more fluid, it goes away but comes back more and more quickly).
