MY LEXUS GX 460 HAS VSC AND VSC OFF AND CHECK ENGINE LIGHT ON AND SOUNDS OFF ALMOST A PUTTER AND CHOKES A LITTLE BUT SPEED IS FINE
Get an OBDII scan and eliminate a lot of guesswork. A Lexus ECU automatically shuts off the VSC/TRAC whenever a fault is detected in the power train so no non-driver controls are applied to wheels---throttle or brake. Hence the light. There is nothing wrong with the VSC.
This happened in my 4runner. Ended up being the gas cap was not producing a good seal.
