Agreed with above. Tesla has same steering/suspension components as any other vehicle.
So to answer your question specifically: depends on speed at which impact occurs, and how high of a curb we are talking, and angle of impact.
But if we assume 30mph, one could expect a bent alloy wheel, possible front lower bumper cover damage, and possibly damaged control arms and other suspension pieces.
If at 2mph, possibly..no damage at all.
