Air bags

“I am writing to demand a recall for a widespread and well-documented defect involving the sunroof drain lines in the Lexus GX460. Owners across multiple model years report that these drains frequently clog, disconnect, or deteriorate, resulting in severe water intrusion into the cabin. This defect is more than an inconvenience. Water intrusion routinely damages the headliner, carpets, and—most concerning—the electrical systems routed under the dash and along the floorboards. Owners have documented failures including: Electrical shorts in junction boxes and harnesses near the driver footwell. Burnt circuits in side mirrors and modules after water exposure. Malfunctioning sensors, warning lights, and throttle response issues directly linked to water entry. Mold growth and corrosion under the dash from standing water. Supporting Evidence from Owners & Forums: GX460 owners have documented water intrusion from clogged drains causing shorts in wiring harnesses and electrical boards. In one case, water damage burned side mirror circuits and caused multiple dashboard warnings. (Source: JustAnswer Lexus mechanic) On ClubLexus forums, GX owners describe water pooling in…”

“The back up camera would go black when reversing, creating a dangerous situation. It’s a known issue with the GX 460 model that when the radio gets corrupted and the infotainment screen goes black it will cause the back up camera to not function properly! I reached out to Lexus and they confirmed the issue is a bad logic (mother ) board that causes this and since it’s out of warranty they will not honor the repair or replacement of this highly dangerous situation. Your assistance is much appreciated!”

“THERE IS A THUD THAT OCCURS IN THE DRIVE TRAIN WHEN ACCELERATING FROM A STOP, OR ACCELERATING FROM A ROLL. THE DEALER SAID ITS NORMAL, BUT IT CANNOT BE NORMAL. IT IS A LITERAL THUD. I HAVE HEARD THIS THUD COUNTLESS TIMES OVER THE LAST YEAR SINCE WE BOUGHT THE CAR. I HAVE ALSO READ ON MANY FORUMS THAT OTHER PEOPLE HAVE THIS SAME ISSUE.”
