I took my 2004 Coupe CC w/ 9,000 miles on a long road trip this past week. About 3 hours into a 4 hour drive, I was driving at interstate speeds (around 70 mph) with the cruise control on when the Cambriocorsa warning light began to flash. I flicked the downshift paddle and the transmission would not shift out of 6. But, a few moments later, everything went back to normal. Then, 15 minutes later, same thing. It performed beautifully for the rest of the trip and the problem has not happened since. Has anyone had a similar experience? Should I get it checked out or just write it off as a phantom gremlin?
