VSC engaging on sharp curves on the freeway, what could have caused it to start

What is your question?

After having the bushings on the rack and pinion replaced the VSC started kicking on when you go into a sharp curve. The dealer has replaced the main computer and a sensor but when I took it home it still does it. They can not figure it out nor did they advise about the recall and they do not think it is related to the other work but it is odd that it started immediately after the bushings were replaced.
