For the second time, I have noticed clear water under the car when I leave in the morning. Not sure if the AC discharges water when the car is turned off, but there is a puddle of water from the night before when I start the car in the morning. Is this normal? 2010 Altima Hybrid, 51k miles on it.

 

It is probably condensation due to the AC. CLear water typically isn't a major issue since there really are no reserves of clear water in the car so its usually condensation of some sort. (unless someone left a bottle of drinking water under th hood? )
