What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2021 Lexus GX, 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.

What the reports in each category say, in the owners' own words

From owner reports, verbatim
i PURCHASED THE GX460 TO AQUIRE THE NEW SAFETY BSM SYSTEM. THE OWNERS MANUAL (PG366) REQIRES THE SIDE MIRROR INDICATOR LIGHT COMES ON AT 9.8 FEET BEHIND THE REAR BUMPER OF MY VEHIVLE. THE LIGHT ON THE SIDE MIRROR COMES ON WHEN THE VEHICLE PASSING ME IS AT MY REAR BUMPER MAKING IT DANGEROUS TO CHANGE LANES AND WOULD NOT ALLOW THE APPROACHING VEHICLE ENOUGH TIME TO AVOID A COLLISION. I HAVE CHECKED WITH 2 DEALERS AND BOTH SAID THERE IS NO ADJUSTMENT FOR THIS CONDITION. I FINALLY WAS ABLE TO HAVE ONE DEALER CHECK THE COMPUTER AND WAS TOLD ALL IS NORMAL. I ASKED MY DAUGHTER-IN-LAW TO WHITNESS THIS EVENT FROM THE BACK SEAT AND SHE VARIFIED MY FINDINGS.

Interior & seats
Reports naming seats, latches, locks, linkages and interior fittings.
From owner reports, verbatim
The driver’s seat is making cracking, clicking, popping, and creaking noises from the lower seat frame, seat rail, or mounting area where the seat attaches to the vehicle body. The noise is most noticeable during braking, acceleration, turning, driving over uneven roads, and when shifting body weight in the seat. It feels as though the seat has movement or play, as if the seat rails, frame, or mounting bolts may not be fully secure. This is a safety concern because the seat is part of the occupant restraint system and is critical for proper seat belt positioning and airbag protection. If the seat frame, rails, or mounting hardware are loose, damaged, worn, or improperly secured, the seat could shift during a sudden stop or collision. In an accident, movement of the seat could reduce seat belt effectiveness, alter occupant positioning relative to airbags, increase the risk of impact with the steering wheel, dashboard, door, or center console, and increase the likelihood of head, neck, chest, back, pelvic, or leg injuries. Unexpected seat movement could also affect driver control immediately before or during a crash. This should not be treated as a simple interior rattle. The seat mounting bolts, rails, locking mechanisms, adjusters, frame components, and floor mounting points should be fully inspected for looseness, improper torque, wear, cracking, or structural failure. I have also found numerous similar owner complaints online from Lexus GX owners reporting clicking, cracking, rocking, or shifting driver seats that feel loose or unstable. Based on forum discussions and owner reports, there appear to be dozens of similar complaints, suggesting this may not be an isolated issue.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
