THE BRAKE AND ACCELERATOR PEDALS ARE TOO CLOSE TOGETHER AND AT THE SAME HEIGHT. ON NUMEROUS OCCASIONS, WHEN ATTEMPTING TO BRAKE I FOUND MYSELF ACCELERATING SINCE THE BRAKE AND ACCELERATOR WERE BOTH DEPRESSED. THE PEDALS ARE NOT ADJUSTABLE AND I REALLY HAVE TO CONCENTRATE WHEN BRAKING TO AVOID THE ACCELERATOR PEDAL OR MY CAR JUST KEEPS ON GOING.

GAS PEDAL WENT ALL THE WAY TO THE FLOOR AND WOULD NOT RELEASE. I KEPT HITTING THE PEDAL TO TRY AND RELEASE IT FOR ABOUT 2 MILES. I KEPT MY FOOT ON THE BRAKE TO TRY AND SLOW THE CAR DOWN, BUT THAT DIDN'T HELP. THE FLOOR MAT WAS NOT UNDER THE PEDAL BECAUSE IT IS TOO SHORT TO REACH IT. AFTER HITTING THE PEDAL AS HARD AS I COULD NUMEROUS TIMES IT RELEASED.
