2011 Lexus RX Brakes Problems

ABS, TRACTION CONTROL, BRAKE LIGHTS & BEEPING SOUND ALL ON. BRAKE PEDAL IS HARD. PEDESTRIANS, OTHER DRIVERS & FAMILY ARE AT RISK DUE TO SAFETY RISK. DIAGNOSIS CODES C1253 - C1256 DURING TEST INDICATES ABS PUMP ASSEMBLY ISSUES. THIS PROBLEM WAS NOTICED BY ME IN LATE AUGUST 2025.

While driving Brake & Abs warning lights displayed on the dash with the warning brake malfunction, Took it to the shop they diagnose Bad brake module. My brake pads & rotors and all scedule maintenance uptodate.

I WAS DRIVING AT APPROXIMATELY 40 MILES PER HOUR AND BEGAN BREAKING BEHIND TRAFFIC AT A STOP LIGHT. I WAS PRESSING DOWN ON THE BRAKE PEDAL AS HARD AS I COULD, THE TIRES BEGAN TO GRIND AND I COULD HEAR AND FEEL THE ENGINE REVVING BECAUSE THE CAR WAS TRYING TO ACCELERATE FORWARD. WHEN THE CAR WAS FAILING TO COME TO A COMPLETE STOP, I PUT THE CAR IN THE "PARK" GEAR. THE CAR QUICKLY CORRECTED WHAT WAS GOING WRONG. THIS WAS THE THIRD OCASSION AND MOST SEVERE. IT'S BEEN MORE THAN TWO YEARS OR SO SINCE THE FIRST TWO OCCURRENCES. I REPORTED THE FIRST TWO INSTANCES, WHEN I TOOK MY CAR IN TO LEXUS FOR REGULAR MAINTENANCE SERVICE. THEY DIDN'T FIND ANY DEFECT. THE FIRST OCCASIONS, I WAS ON A PARKING LOT DRIVING SLOWLY LOOKING A PLACE TO PART AT A RETAIL ESTABLISHMENT.
