I second Bill's clarification there. And as for the coolant leak, my 07 N/A NEVER left a puddle on the floor but there was coolant on the bottom right of the engine. As with many, the "weeping" only occurs when hot. It showed up with the coolant level light blinking on during acceleration or hard cornering - the level in the reservoir was low enough that shifting the coolant in those conditions would light the lamp.

2007 2.4L N/A. Stock + some pretty crap.

EDIT: If a car is using coolant and you've added coolant more then once within several weeks, there's a leak or a bad headgasket.

It could possibly be a head gasket. Check your oil and see if the oil level has risen, or if you have anything on the dipstick that resembles chocolate mousse or water bubbles. also check the water reservoir for any oil film on top of the coolant.

I went through this with mine last fall. It was in fact the coolant level sensor in the tank.
Like it was said earlier, they are not expensive, you just have to buy the whole tank since the sensor is not replaceable.
Very easy to switch out the tank. Then just burp the system.

If you do have to change the tank, it is high enough that you don't have to drain the whole system. just siphon out the reservoir and replace it.
