Whenever i'm driving highway speeds of 50 or higher, the following occurs. When turning right on a sharp curve the car tends to over steer to the right causing me to feel that the car will go out of control. I never had this type of issue with any other car.

Any suggestions?

Thank You,
Denis

Of course you have already checked the obvious....tire pressure, especially the rear.

Oversteering problems are usually because of a rear suspension problem. Look for a broken strut or trailing arm. To check struts, push down on the corners of the car, it should be hard to do and come right back up without a residual bump.
Try gently pushing the car from side to side on the rear right corner, it should not give.
This sounds dangerous to me, have it looked at if you don't find anything obvious.
