Open the full vehicle complaint log (all categories)WHILE BRAKING AGGRESSIVELY ON A DRY STREET IN A STRAIGHT LINE, THE ABS SYSTEM KICKED IN FOR A BRIEF SECOND AND THEN IT RELEASED THE BRAKES ALL TOGETHER - RESULTING IN COMPLETE LOSS OF ALL BRAKING CAPABILITY. BRAKING CAPABILITY WAS RESTORED AFTER THE PEDALS WAS RELEASED ALL TOGETHER AND RE APPLIED. THIS HAPPENED TWICE OVER THE PAST 6 MONTHS. ON 2017/10/13 I TOOK THE VEHICLE IN FOR A COMPREHENSIVE INSPECTION OF THE BRAKING SYSTEM BY A TOYOTA AUTHORIZED DEALER BUT THEY HAD NOT IDENTIFIED ANY FAULTS AND CLAIM THE SYSTEM IS OPERATING AS EXPECTED.
BRAKES ARE NOT ADEQUATE FOR MODEL. ROTORS WARP AROUND 15K AND KEEP WARPING WHEN REPLACED OR RESURFACED. BRAKING IS NOT SOLID, IS SLOW, AND STEERING WHEEL SHAKE RESULTS WHEN WARPING OCCURS. BRAKES DO NOT ADEQUATELY GRAB. BRAKES ALSO ARE SLOW TO REACT WITH ABS ON CORNERS, MAKE SOUNDS AND BRAKES ARE SUBSTANDARD FOR MODEL. ALL OF THIS HAS HAPPENED UNDER AT 15K AND 23K IN MY CAR. DEALER SAID IT''S A KNOWN ISSUE AND TELLS PEOPLE TO DOWNSHIFT (IN AN AUTOMATIC!) INSTEAD OF BRAKE. MANY COMPLAINTS IN INTERNET FORMULA REGARDING THE SAME. PEOPLE COULD GET SERIOUSLY HURT WITH THESE ISSUES. NEEDS TO BE RECALLED FOR BRAKES AND A STRONGER BRAKING SYSTEM ISSUED.
