While drivimg under cruise control at approximately 70 mph, a continuous loud beep occurred, accompanied with the following warnings on the dashboard: Red "brake" warning and yellow "((!))", "ABS" (antilock brake system), and "vsc" (vehicle stability control) warnings. Attempting to pull over and stop, the brakes had no power assistance but, fortunately, could be operated under heavy foot pressure. After pulling over and stopping and restarting the engine, all the warnings and the beep were still there while the car was driven to a safer location at a gas station. Braking was still entirely under foot pressure only. As this was in Canada, driver turned off the engine while trying to decide the next course of action. After a few minutes, the engine was again started in order to move the car slightly in the parking lot (to get away from a puddle) and all systems, including brake power assistance, were now operating normally with all the warnings off. The problem has not recurred. The car was taken to the dealer about two weeks later and the diagnostic report states, "could not duplicate customer's complaint". thus, no repair was done nor further action was taken by the dealer.
