Samsung Refrigerator Warranty Doesn't Cover Gas Pipe Replacement

I paid twice as much for a Samsung refrigerator in 2017 because it was advertised as having the best motor and compressor warranty available. This model comes with a 10-year warranty on both the motor and the compressor. I do not have any regrets about making the purchase, with the exception of the present moment, when I discovered that the gas pipes have rusted and require replacement; however, it appears that this problem is not covered by the warranty. There is a ten-year warranty on both the motor and the compressor, but the gas delivery pipes are not covered by the warranty. Why am I required to pay for a problem that is not due to my own actions? I demand that the warranty cover the cost of the repair.
