I havent run across any issues with an electrical smell myself when the esc is turned on.This may be a fault with wiring to a sensor or solenoid or a sensor or solenoid at fault here.If you can locate the source of the smell this should lead to what needs replaced and/or to see if any wiring needs repaired as well.
O.k.,you can find out from a dealer with your vehicles VIN number if the recall has been performed or not on this here.They can usually tell you over the phone in most cases.
