Mine had the VSC light on. Once I was looking for a dead fuse for something and found a dead fuse; I changed it and that took the Check VSC light away. I am sorry can't remember which one it was.

I'm sure you have sorted out your problems by now, but, perhaps for the benefit of others I can make the following comments:
The VSC light will not infrequently come on when the battery has a bad cell or two. The same issue can also cause the engine to flood on initial startup. There are instructions in the owner's manual for clearing the flooded cylinders. Have your battery LOAD tested before the warranty expires even if it seems to be functioning well. The valve cover gaskets often leak and this is usually because the bolts that hold them in place have loosened. Simply tighten them gently. Most are accessible with common tools and a little care. Something else that might fail after MANY miles is the fuel pulse damper. You'll smell gasoline and be unable to find the leak. Look to that device first. It's cheap at about any parts store and takes about 10 minutes to replace (DIY).
Good luck with what is probably the best modern car ever made!

There is a way to reset the VSC warning light by disconnecting the battery, putting the car in neutral, applying the parking brake, reconnecting the battery, then start the car, I'm not sure if I have the sequence right, but it's in the owner's manual that comes in the glove box. The entire dashboard makes a bunch of noise as the car's actuators sound like they are resetting themselves; you need to wait a couple minutes literally for it to do this, then the light should be out. A loose battery connection can cause this as well as a weak battery. These cars have a reputation for going through batteries.
I had to do this yesterday as it disables the traction control as well, which I need here in Michigan, they are combined functions.
I own several Lexus vehicles, the electrical systems can drive you nuts at times. They took some shortcuts with the combining of sensors to warning lights which have nothing to do with the problem that is indicated by the warning light. At first glance you would think that is what caused the problem, and most of the time you will be wrong.
Always consult one of the Lexus online clubs, they are invaluable for information on how to fix the many idiosyncrasies of these vehicles.
