We have continuously had the same problem with our 2021 Tahoe. Every time it rains, the driver's side floor mat gets soaked. We took it in to the dealer. They blew out the drain lines and said it was fixed, but it still has the same problem. Fortunately we live in Southern California, so it only rains a few time a year, but it is incredibly frustrating that there is no solution to this problem. GM should be able to solve the problem. Has anyone had success solving this problem.
