Rain onset detection glazing auto-close

A vehicle system may include a plurality of exterior capacitive sensors, such as door handles, and a controller in communication with the plurality of capacitive sensors. The controller may be configured to identify a rain condition based on sensor data received from at least one of the exterior capacitive sensors of the vehicle; ensure an absence of a key fob in proximity of the at least one locked handle and an absence of a subsequent door opening occurrence when unlocked to confirm the rain condition; and initiate a closure action to a power actuator associated with an open vehicle window for a confirmed rain condition.
