What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2003 Lexus Gs, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
WHEN BACKING INTO A PARKING SPACE WITH MY FOOT ON THE BRAKE, THE RPMS SURGED CAUSING SPEED TO INCREASE SUDDENLY. I PLACE THE CAR IN NEUTRAL AND THE RPMS CONTINUED TO SURGE FOR ABOUT THREE SECONDS AND THEN RETURNED TO NORMAL. WHILE WAITING AT A TRAFFIC SIGNAL, WITH MY FOOT ON THE BRAKE, THE RPMS SUDDENLY SURGED AND I AGAIN PLACED THE CAR IN NEUTRAL. THE SURGE CONTINUED FOR ABOUT THREE SECONDS AGAIN. ON ONE OTHER OCCASION, WHEN SHIFTING FROM REVERSE TO DRIVE WHILE EXITING A PARKING SPACE, THE RPMS SURGED FOR ABOUT TWO SECONDS AND THEN RETURNED TO NORMAL. THE VEHICLE SEEMS TO ACCELERATE SUDDENLY ON ITS OWN WITHOUT DEPRESSING THE GAS PEDAL. *TR

Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.
From owner reports, verbatim
ACCELERATION PEDAL PROBLEM. CAR FAILS TO RESPOND TO ACCELERATION PEDAL SOMETIMES WHILE IN MOTION. CAR CAN STOP MOVING IN TRAFFIC OR DURING TURNS (ESPECIALLY LEFT TURNS). THIS IS VERY DANGEROUS AND LIFE THREATENING. ALTHOUGH PEDAL SENSOR WAS CHANGED GIVEN THE ERROR CODE, THE CAR STILL SHOW THE SAME ISSUE. LEXUS MUST TAKE RESPONSIBILITY FOR DANGEROUS DESIGN AS IT LACKS A FAIL SAFE MECHANISM TO THEIR DRIVE BY WIRE. FAILURE IN ACCELERATION IS AS DANGEROUS AS FAILURE IN BRAKING.
