Traction Control is the wrong terminology. It is ESC or Electronic Stability Control which senses the car getting out of shape, cuts power and brakes a spinning
wheel to help maintain the direction of travel. It can help in slippery conditions, especially ice patches or deep puddles, by preventing a sudden loss of control, but as snork mentions above, it cuts in very quickly which may not help in snow at low speed. Winter Tires are a must-have for the Genesis if you regularly experience snow, ice or temperatures below 45degF. The newer model years Michelin OEM All-Season tires are more geared to economy and longer tread life (Dunlops excepted) than winter traction and are hopeless in snow. Turning off the ESC doesn't eliminate it completely but does allow some
wheel spin, which may help in snowy conditions, while still cutting in if the car gets really out of shape.
