The cruise system malfunctioned. In multiple scenarios (at least three) when the cruise control was set, if the accelerator is pushed while the cruise control is engaged, the vehicle will continue to accelerate even if the accelerator is released. Disengaging the cruise control via brake usage or by hand on the steering wheel does not stop the unwanted acceleration. The only way to stop the acceleration is to move it from in Drive to Neutral. At that point, an error populates on the dash and the acceleration stops with cruise control disengagement as well. The issue is fixed upon placing the car back in Drive. Unsolicited acceleration puts the driver and others on the road at risk. The issue has not been presented to a dealer or service center for review and has not been inspected by other entities. No dash messages or warnings occurred prior to the failure.
