What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2012 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.

TAKATA RECALL. UNACCEPTABLE WAIT TIME FOR REMEDY (REPLACEMENT.) IN OUR PRESENT HOME STATE OF FLORIDA, ANOTHER(!!) FLORIDIAN HAS DIED -- THIS TIME, A 34YR OLD WOMAN, 07.28.2017. DURING THE MANDATORY HURRICANE EVACUATION, OUR FAMILY WAS FORCED TO USE OUR FRONT PASSENGER SEAT. THANK G-D NOTHING HAPPENED, BUT THIS CORRECTIVE PERIOD IS GONE ON TOO LONG. WE HAVE BEEN WAITING MONTHS FOR RESOLUTION -- AND ALL WE ARE TOLD IS THAT THE NECESSARY PART IS UNAVAILABLE AND TO WAIT LONGER -- AND IN THE INTERIM PLACE OUR FAMILY IN A POTENTIALLY DEADLY SITUATION. WHAT IS IT GOING TO TAKE TO GET THE REPLACEMENT AIR BAG?! DOES SOMEONE'S TEENAGE CHILD HAVE TO DIE DURING A MANDATORY EVACUATION IN ORDER FOR RESOLUTION TO HAPPEN?! I AM TIRED OF BEING PATIENT. PLEASE, SOMEONE EXPLAIN THE LACK OF APPARENT URGENCY. HOW MANY MORE PEOPLE NEED TO DIE? THE DEATH TOLL ESTIMATE IS NOW 19. HOW MANY MORE PEOPLE NEED TO DIE BEFORE THE REST OF US GET ANSWERS?!?!

THIS CONFIRMS THE COOLANT VALLEY IS INDEED LEAKING AND WILL NEED TO BE RESEALED. RESEAL COOLANT VALLEY AND REPLACE SEALS/GASKETS NECESSARY. Driver comment: This is a known issue with Toyota/Lexus V8 engines. Toyota/Lexus needs to take ownership (recall) and fix the worn out seals without charge.
