leaking from quick connection on heater core inside under the glove box. Replacement heater core was $35.00 at local parts store. Was quoted $800.00 to install at dealership. Did repair myself in 5 hours for free. its a bad design and could be done in a half hour if they would put an access door in engine bay.
