2007 LEXUS LS460L Vehicle Speed Control Problems

THE VEHICLE DASHBOARD COMES UP WITH SEVERAL WARNINGS. 1) CHECK VSC SYSTEM. 2) CHECK PCS SYSTEM. 3)CHECK ABS. 4) BRAKE MALFUNCTION. 5) CHECK BRAKE SYSTEM. IT SAYS TO PULL OVER AND TO NOT DRIVE THE VEHICLE. LEXUS DIAGNOSED MY VEHICLE AS NEEDING TO HAVE THE BRAKE ACTUATOR REPLACED AT A COST OF NEARLY $3500! THE DEALER SAID THAT THEY HAD ALREADY REPLACED SEVERAL OF THESE ON THIS MODEL VEHICLE IN JUST THE PAST FEW MONTHS. AFTER LOOKING ONLINE, I FOUND THAT THERE ARE A LOT OF LEXUS OWNERS WITH THE EXACT SAME PROBLEM THAT OCCURRED IN MY VEHICLE, WITH SOME OWNERS ALREADY HAVING THE PART REPLACED TWICE! THIS IS OBVIOUSLY AN ONGOING PROBLEM. LEXUS HAVE SINCE MADE A NEWER, IMPROVED VERSION OF THE PART. THERE WAS ALSO A TSIB (TECHNICAL SERVICE INFORMATION BULLETIN) ISSUED ON DECEMBER 2, 2009 FOR "BRAKE ACTUATOR KNOCK NOISE" L-SB-0178-09 LEXUS ARE NOW COVERING THIS PART...

TL* THE CONTACT OWNS A 2007 LEXUS LS460L. THE CONTACT STATED THAT WHEN BRAKING TO A COMPLETE STOP, THE ENGINE RPMS WOULD INCREASE EXCESSIVELY. IN ADDITION, THE VEHICLE WOULD SPORADICALLY LOSE POWER WHEN ATTEMPTING A RIGHT TURN. THE VEHICLE WAS TAKEN TO THE DEALER WHO WAS UNABLE TO DUPLICATE THE FAILURE. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 55,000 AND THE CURRENT MILEAGE WAS 64,000.
