Owner-reported complaints naming the driver-assistance system, filed with NHTSA
Data refreshed
Driver assistance reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

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

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 BEING DONE. *TR
