Toyota Sienna electric sliding door latching issues with previous latches replaced due to rust on Toyota Sienna

Some Toyota Sienna owners report experiencing electric sliding door latching issues, particularly with models from 2008 and later, where corrosion on the latch can lead to notchy opening and closing. Additionally, there are reports of 172 problems related to door latches, indicating a recurring concern among owners. To address issues such as doors not closing properly or noisy operation, some owners have found temporary solutions like putting the door in manual mode and supporting the door's weight during operation. Applying lithium grease has also been suggested to improve door functionality.
