('06 AT) Power steering light on - what's up?

Ok,

So picked up a new-to-me Mazda5, 2006 with AT. Power steering light kicked on once before we bought it, figured it's still under warranty (28k miles on it), didn't worry too much about it.

I added fluid, was below 'min,' light still kicks on intermittently. Not always sure when, it's wife's car so I don't drive it much. She mentioned that it seems to kick on 'in parking lots/parking lot driving.' Took this as low-speed turns, but she doesn't crank the wheel when at a stop, always rolling.

Based on the fact that they've got a light just for PS system, I'm thinking they've had issues with this before? What's likely culprit? I'd just assume look it over myself and not just take it to a dealer b/c an idiot light is on...

Should I be looking for a leak in the system? Likely places?
Any ideas would be appreciated.

Thanks,
Nick

I would. Just had P/S leak fixed. No light though.

The first place I would look is pointed to in the second page of this TSB.

The leak described in the TSB is caused by burrs on your nipple! (boom07)

Nothing worse than burrs on a nipple.
