Should I be worried about things to come?

I was on my way to work this morning and when I came to a stop at one of the lights, the display turns yellow and I get a warning from the car. The display starts telling me that the Hill hold control was disabled and to have the ESP system serviced.
On the way home everything was fine. Do you think it was a hick-up of a new car from the electrical system ? I plan on calling the dealer tomorrow.
