I HAVE A NEW 2010 TOYOTA PRIUS, PURCHASED 15 JAN. 2010. I HAVE SINCE PUT 3,292 MILES ON THE VEHICLE ON A TRIP FROM WASHINGTON TO CALIFORNIA AND BACK, DURING WHICH CONDITIONS FROM MOUNTAINS, SNOW AND ICE, AND DRY FREEWAY CONDITIONS WERE ENCOUNTERED. THE RANDOM PROBLEM OCCURRED SEVERAL TIMES WHEN USING THE BRAKE PEDAL TO DISCONNECT THE CRUISE CONTROL TO SLOW DOWN. THE PROBLEM IS MOST PRONOUNCED WHEN THE POWER APPLIED TO THE VEHICLE IS INCREASING TO MAINTAIN SELECTED CRUISE CONTROL SPEED. WHEN THE BRAKE IS APPLIED IN THESE SITUATIONS, THE VEHICLE TRIES TO ACCELERATE FOR A SECOND OR SO, GIVING THE DRIVER THE FEELING OF NOT BEING IN CONTROL. THE PROBLEM IS MOST PRONOUNCED WHEN CLIMBING A STEEP (6% TO 8%) GRADE. IN THOSE CASES (2 TO 3 TIMES) THE POWER SURGE WAS PRONOUNCED AND SEEMED TO LAST FOR 2 TO 3 SECONDS WITH THE SMELL OF BURNING BRAKES AFTER THE ACCELERATION ENDED. ON THE FREEWAY, WHILE THE PROBLEM IS LESS SEVERE, THE DRIVER IS LEFT WITH AN UNCOMFORTABLE SITUATION IF COMING UP ON A SLOWER MOVING VEHICLE AS YOUR VEHICLE CONTINUES TO GAIN ON THE VEHICLE AHEAD EVEN THOUGH YOU ARE TRYING TO SLOW DOWN. THESE INCIDENTS OCCURRED OVER A PERIOD OF THREE WEEKS, SO THE DATE BELOW IS NOT ACCURATE. *TR
