Brake Master Cylinder problems of the 2016 Chevrolet Suburban

Rollling down my drive way my brakes went out. Very spongy. Pressed multiple times and was able to come to a stop with the help of my front bushes. Master cylinder is full brakes are less than a year. I see online that this is a problem with 2014-2018 chevy trucks and suvs. If my wife was driving she could have been hurt. Heaven forbid my kids where in there too. This is obviously a defect in manufacturing and design and should be remedied by chevy.
