Vehicle will sometimes veer to the right at interstate speeds. Alignment is ok. Dealer checked out suspension and steering mechanism

What is your question?

Checked alignment, ok. Dealer checked suspension and tightness of steering brake mechanism and all tight and ok. Daughter says vehicle will drift a little to left and right when she drives it. I don't feel it when I drive it. It only veered. It has not veered right on me, only her.

What makes this problem better or worse?
