ON MULTIPLE OCCASIONS WENT TO PRESS BRAKE PEDAL BUT PEDAL DOESN'T DEPRESS ALL THE WAY DOWN, AS IF THERE WAS A BLOCK OF WOOD OR SOMETHING PREVENTING IT. "REGEN BRAKE DISABLED" LIGHT WOULD APPEAR ON DASH. BRAKING POWER ADVERSELY AFFECTED DURING THESE EPISODES. CAUSING TO PRESS DOWN ON BRAKE VERY HARD JUST TO STOP. ON SOME OCCASIONS THE MULTIPLE ATTEMPTS AT PRESSING OF BREAK WOULD CAUSE PEDAL TO DEPRESS A LITTLE MORE AND ON SOME TIMES NON DEPRESSING BRAKE PEDAL SENSATION WOULD PERSIST, WITH ADVERSE BRAKE AFFECT.... SOMETIMES EXPERIENCING A HYPERSENSITIVITY TO PRESSING ON BRAKE WITH A CHOPPY BRAKING IMPACT AND SOMETIMES EXPERIENCING A VERY LIMITED BRAKING EFFECT, CAUSING ONE TO ALMOST HAVE TO "STAND UP" ON THE BREAK IN ORDER TO PREVENT HITTING WHOMEVER MIGHT BE IN FRONT. I RECALL STARTING TO EXPERIENCE THIS INITIALLY ABOUT A YEAR AGO - ROUGHLY APR 2018 EST.. BETWEEN THEN AND RECENTLY SOMETIMES BRAKING WOULD BE MORE PROBLEMSOME THEN OTHER TIMES THE EXPERIENCES SEEM TO WAX AND WAIN BUT ABOUT MID DECEMBER 2019 AFTER PARKING AT WORK IN THE MORNING AND RETURNING TO THE CAR TO GO BACK HOME. IT APPEARED THE EMERGENCY PARKING BRAKE I ENGAGED WAS STUCK. WHEN I TURNED THE VEHICLE ON I GOT THE SAME ILLUMINATED REGENS BRAKE DISABLED SIGNAL ON THE DASH AND IT APPEARED I COULDN'T GET THE CAR OUT OF PARK. I HAD TO LEAVE VEHICLE AT WORK. I WAS AWAY FROM WORK A WEEK. UPON RETURN THE CAR STARTED WITHOUT THE REGEN BRAKE DISABLED SIGNAL BUT WHEN I RELEASE EMERGENCY BRAKE & SHIFTED CAR INTO REVER
