general problems of the 2011 Porsche Cayman

I was driving the car at approximately 47 mph in traffic and the on board computer displayed the warning message "transmission temperature too high" followed by the message "transmission emergency run". The car at this point stopped moving and I coasted to a stop in traffic. The immediate cut off of the power train and pdk transmission poses a serious threat to safety that could lead to a rear-end collision due to the immediate disengagement of the transmission. The car was taken to the dealership and information on the incident was sent to Porsche for a problem determination. Porsche has since decided to replace the entire transmission.
