Toyota Sequoia rear liftgate window inoperable due to rusted vertical window rails on Toyota Sequoia

Some Toyota Sequoia owners report experiencing issues with the rear liftgate window becoming inoperable due to rusted vertical window rails. This problem stems from the design of the rear door hatch, which allows water and salt to enter, leading to rust on the non-galvanized metallic rails. As a result, some owners find that the liftgate window no longer operates properly, making it difficult to raise or lower the window. To mitigate this issue, it is recommended that owners lubricate the rails annually to prevent rust and ensure smooth operation of the liftgate window.
