The contact owns a 2014 Volkswagen Passat. The contact stated that while the vehicle was parked, she noticed an excessive amount of fluid underneath the vehicle. The vehicle was taken to an independent mechanic, who performed an unknown repair; however, the failure recurred. The vehicle was then taken to another independent mechanic, who performed an oil change and added antifreeze. The next morning, the contact inspected the vehicle and noticed the oil and antifreeze were empty. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 119,000.
One day at about 25,000 miles I noticed that the passenger side vents were not receiving any hot air to warm the car. There was plenty of heat coming out of the drivers side, but only cold air coming from the passenger side. Took it into the dealership for diagnosis and they said that the heater core is clogged. So there is some type of contaminate in the cooling system effecting the heater core. They are replacing the heater core under warranty, bu I hope it doesn't affect the rest of the cooling system.
