1998 LEXUS LS400 Vehicle Speed Control Problems

TWICE, WITH TWO DIFFERENT DRIVERS, THIS VEHICLE HAS ACCELERATED/SURGED AT A STOP. THE VEHICLE WAS ABLE TO BE HELD STEADY BY PRESSING THE BRAKE AS HARD AS POSSIBLE, BUT VEHICLE STILL SURGED AND TRIED TO MOVE FORWARD. ON THE FIRST INCIDENT, THE VEHICLE WAS PUT IN NEUTRAL AND CONTINUED TO REV MOMENTARILY. AFTER THE FIRST INCIDENT, THE LEXUS OEM FLOOR MAT (STANDARD, NOT ALL SEASON) WAS REMOVED. THE SAME EVENT OCCURRED AGAIN TONIGHT WITH A DIFFERENT DRIVER AND THE FLOOR MAT STILL REMOVED. I AM QUITE CONCERNED THIS MAY BE RELATED TO OTHER TOYOTA RECALLS. *TR

TL* THE CONTACT OWNS A 1998 LEXUS LS400. THE CONTACT STATED THAT THE VEHICLE SUDDENLY ACCELERATED WITHOUT WARNING. THE VEHICLE TRAVELED INTO A RESIDENTIAL GARAGE AND CRASHED INTO A WALL. A POLICE REPORT WAS NOT FILED AND NO INJURIES WERE REPORTED. THE VEHICLE WAS TAKEN TO THE DEALER. THE SHOP TECHNICIAN DIAGNOSED THE WRONG PROBLEM. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS REPAIRED. THE FAILURE MILEAGE WAS 153,000 AND THE CURRENT MILEAGE WAS 160,000. UPDATED 07/22/14 MA

ACCELERATION STUCK, RPMS LOCK IN AT ABOUT 2000. FAILURE OCCURS ABOUT ONCE OR TWICE DAY, BUT USUALLY ONLY IF THE AIR CONDITION IS TURNED OFF. THIS HAS BEEN GOING ON FOR YEARS NOW WITH MY VEHICLE. I TURN OFF VEHICLE AND RESTART IT TO CORRECT THE PROBLEM AND REGAIN CONTROL OF THE ACCELERATOR, IT ALMOST ALWAYS RETURNS AFTER RESTART. I BELIEVE THIS MAY BE CAUSED BY FAULT IN LEXUS ELECTRONIC THROTTLE SYSTEM AND SINCE YOU ALL ARE FINALLY INVESTIGATING THIS I THOUGHT I SHOULD REPORT IT IN CASE YOU WOULD LIKE TO EXAMINE MY VEHICLE SINCE IT OCCURS SO OFTEN. I WAS TOLD BY LEXUS I SHOULD PURCHASE A NEW THROTTLE BODY, I HAVEN'T DONE SO BECAUSE I DO NOT SEE HOW THAT WILL CORRECT MY ACCELERATOR FROM STICKING IN ONE POSITION DURING DRIVING AND I BELIEVE THIS IS MORE OF A SERIOUS SAFETY ISSUE NOW WITH THE RECALLS FINALLY...
