NHTSA complaint: 2010 TOYOTA PRIUS — SERVICE BRAKES, HYDRAULIC
MULTIPLE EVENTS/FAILURES, HERE IS A SUMMARY: 1) WHILE BRAKING OVER ROUGHER ROAD CONDITIONS -- NOT POTHOLES, BUT REGULAR ROUGHNESS/BUMPS IN ROADS -- BRAKES FEEL LIKE THEY MOMENTARILY NO LONGER FUNCTION/GO OUT. AS SOON AS YOU RETURN TO SMOOTH ROAD SURFACES, THE PROBLEM CORRECTS ITSELF. THIS HAS OCCURRED ON NUMEROUS OCCASIONS, THE DEALERSHIP WITH WHOM I PURCHASED MY VEHICLE WERE UNAWARE OF THE PROBLEM WHEN I CALLED THEM, EVEN THOUGHT IT HAS BEEN DISCUSSED IN THE NATIONAL NEWS. 2) BRAKE MALFUNCTION ON SLIPPERY ROADS. I WAS DRIVING TO WORK AND GOING VERY SLOW, LEAVING MORE THAN ENOUGH SPACE TO STOP FROM THE CAR IN FRONT OF ME. I APPROACHED A RED LIGHT AND LIGHTLY APPLIED THE BRAKES. HAVING PLENTY OF SPACE TO STOP, I REALIZED THAT MY CAR WAS NOT SLOWING AS IT SHOULD. REGARDLESS OF THE PRESSURE APPLIED THERE WAS NO CHANGE. I ENDED UP STOPPING BY REARENDING THE VEHICLE IN FRONT OF ME. THE DAMAGE WAS MINIMAL, BUT SCARY NONETHELESS. *TR
