The component that failed is the roof rail clips that hold the roof rack to the vehicle (Toyota Service Bulletin T-SB-0040-24). The clips under the rail fail and cause water to leak into the headliner and down the A-pillars on both sides of the vehicle. It presents itself by causing water staining where the headliner meets the A-pillar cover. This issue presented itself in January of 2023, a few months after we bought the vehicle. Toyota Bountiful (Utah) tried to tell us that it is the sunroof drain lines that are clogged and required a $100 service to clear them which is an annual service. After some push back they found the problem with the roof rack clips. However, they only replaced the passenger side and neglected to repair both sides. April of 2025 the driverside failed and Toyota Bountiful once again confirmed that the driverside clips failed. This creates a danger to the front occupants of the vehicle by allowing a possible mold issue within the cabin. Secondly, it allows water into the front curtain airbags of the vehicle.
