Toyota Sienna side door won't close automatically, must be closed manually on Toyota Sienna

Some Toyota Sienna owners report experiencing issues with their side doors failing to close automatically, necessitating manual closure. Common reasons for this problem include latch motor failure, which can prevent the door from closing automatically, and frayed cables that may break over time, leading to difficulties in automatic closure. Additionally, some owners find that circuit overloads can hinder the door's ability to latch properly, while hinge issues may cause the door to not stay closed or open unexpectedly. It is recommended that owners investigate these potential causes and seek appropriate repairs to restore the door's functionality.
