The brake light is on by default because of the vsc warning light and the skid warning light is also on because the computer has detected a malfunction in the VSC system which stands for vehicle skid control. Checking the code number will require a scan tool that either a dealership for Lexus or Toyota can check. This car should still be under warranty. If it is not under warranty and you would like a second opinion. If you can get the code number that set the VSC system I would b the glad to advise you further.
