Cruise Control problems of the 2011 Volkswagen Tiguan

The cruise control speed setting, under certain conditions, will increase when the decrease speed button is pressed. More specifically, when reducing the cruise control speed using the toggle switch at the end of turn signal stem on the left of the steering column, the cruise speed will increase back to the original speed if there is any hesitation in resetting the speed. For example, if the speed is set at 55 and the toggle switch is pressed 5 times to slow the car and reset the speed to 50, if there is a hesitation of a second or two and then toggle again to set the speed at 49, the cruise will reset to 55 and the car will begin accelerating back to the original speed. This occurs even though the only button pressed is the reduce speed button. This occurs at any speed setting (this condition occurred 100% of the times tested at speeds ranging from 40 to 70 mph) and under any conditions (uphill, down hill, and flat driving) - set the speed lower, hesitate, and then reduce the speed further - causes the cruise to reset back to the original speed and the car to accelerate unexpectedly. Hope this is clear - email or call if this requires further explanation.
