I have a 2012 Kia Sedona and I have noticed under the front passenger side of the car there is some type of leak. I can not figure out what may be leaking on the front passenger side under the car

If it's clear water most likely the A/C condensation drain. Normal. All is well. But if it's greenish, orangeish (that really is a word), has the distinct odor of engine coolant could be a leak from many places. Rub a tiny bit between your fingers. If it's water. good. If it's oily and colored you need to begin to trace the coolant leak
