Radiator Problems of Volkswagen Tiguan

Gradual coolant leak with dealership knowledge upon sale of the car (44,000 miles). Refill overflow every 8 to 10 months. Leak unknown. Had to increase refilling gradually over time, thought it was due to use from work in 2016. Increased to once every few months 2017. Fill every week or two from 2018 to 2019. . . . Daily since late 2019 to now. Engine does not over heat. Refilling over flow coolant tank every time I need to drive the car. I have to turn on the car, pop the hood, and see how much it goes below the minimum line. Then fill to maximum. Daily refill started around October 2019. Received transmission flush and fuel induction service. Mechanic said I need a water pump and radiator. He thought the recall would cover my car but said my VIN wasn't showing a defect. I'm not sure why it's not. Dealership knew about the leak upon the sale of the car. Help!! I had no idea the leak was going to get worse. The dealership made it sound like something minor I just had to deal with.
