I was driving my crossfire and the speedometer went to 0, a lot of dummy lights came on, the wing came up (but faulted at button) the car was driving fine. Shut car off for a few minutes then restarted and everything was back to normal and worked just fine. This has happened 3 times so far and I don't want to end up stranded. I love this car and don't want to get rid of it either. Anybody know what might be causing this problem?
