Brake Fluid Leak problems of the 2021 Chevrolet Traverse

We bought a 2021 chevy Traverse and the day after purchase the brakes began making a grinding noise off and on. Three weeks to the day after purchase, may 11, behind the driver side back tire was a puddle of darker fluid. The brakes began grinding worse. I left for work and when I returned home under the carport where the Traverse was parked was fluid where each tire has sat. I drove 15 miles to my next duty spot for the day and brakes were grinding horribly. . When I got to my destination I popped the hood to find the reservoir where the brake fluid goes completely empty. It looked as if it never had fluid in it to begin with. The dealership sent a tow truck to my location and picked the vehicle up.
