Hi,
Dont panic, 95% of the time it will be nothing serious, and it will probably be covered by warranty anyway. What year of your warranty are you in?
It could well be as simple as the brake pedal switch faulty or out of adjustment. The only way your going to know for sure is to have it hooked up to Examiner or similar diagnostics equipment.
Have you tried switching off the ignition, and the re-starting to see if its still the same?
