Yes, this is a 2021 S that was built in August of that year. Had to lift the car up. There's a large panel on the front underside of the car. If you remove it, the spot where the drain line connects to the firewall is right there at the bottom in the center, easily accessible, and easy to disconnect. I fed the Kool-it tube up through drain at the firewall so it got to the coil. I put one can in, left it for a few hours, then put another one in. Reconnected the drain tube and put the panel back on securely. I won't call it a fix, but it did help. Probably needs two more cans. Mine was really bad. This was a really silly problem for such an advanced piece of tech.
