20250925AIR 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, andâmost concerningâthe 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.
