WHILE BACKING INTO A PARKING SPACE, AT A VERY SLOW SPEED, THE BRAKES FAILED AND THE CAR HIT THE BUILDING BEHIND THE PARKING SPOT. NEXT DAY, WHILE PARKING AT A CONVENIENCE STORE, ALSO AT A VERY SLOW SPEED, THE BRAKES FAILED AGAIN AND HIT A POST. BOTH TIMES THE BRAKE PEDAL WENT ALL THE WAY TO THE FLOOR. THE FIRST TIME, I THOUGHT I HAD MADE A MISTAKE, BUT AFTER THE SECOND INCIDENT I REALIZED THE BRAKES FAILED. ON THE WAY HOME, I FOUND THAT I COULD DUPLICATE THE PROBLEM AT WILL WHILE AT A VERY SLOW SPEED (SIMULATED PARKING SITUATION). I CONTACTED THE DEALER AND THEY PICKED THE CAR UP FOR DIAGNOSTICS AND REPAIR. BOTH PARKING INCIDENTS CAUSED BODY DAMAGE. I AM GRATEFUL THERE WERE NO INJURIES TO OTHERS OR NO DAMAGE TO PROPERTY OTHER THAN MY CAR.
