I found liquid underneath my car on my parking lot after work. I realized it was badly leaking from the somewhere of the engine. My mechanic came and open the cooling system cap for the investigation. It found the coolant was mixed with oil (probably the transmission oil). the liquid is in creamy butter color. The engine light was on and temperature indicator was at nearly "H" level. Then I called Honda roadside assistant to tow the car to the dealer at once. I am waiting for the Honda confirmation of the warranty. I don't understand why it would be happen on a 2 years old car and how it could be passed the inspection in the factory. This is my 2nd owned Odyssey. The first one did not have this issue. I will update the status.
