All four windows on my 2022 sienna when rolled down and then rolled back up have water streaks on the outside even 3 days after a raining day. I am afraid water is trapping inside the door panel and can create potential mold issue.

Is this normal for everyone on the forum, the service advisor told me it’s normal, but this doesn’t happen to my old prius 2011.

Although I haven't verified the Sienna, the bottom of most car doors have drain holes. Poor washing techniques can lead to those clogging up. BTDT

As stated. Automotive doors have drain holes. It should drain by itself.

Post some pics please so can see water amount.

Presumably did not wash after rain and windows all the way up?

Have discovered that sometimes easy to glance/brush window button and window will slide down a bit [even though supposed to be Auto] and even though it looks closed the window(s) are wee bit open.

I've done this myself several times but luckily not in rainy weather.

I will post pic when the right scenario arises , but basically all 4 windows are fully secured and closed when raining or washing car. Just that water streak shown when rolling down window then roll up on the 2nd/3rd day. I can understand if it shows up within hours or a day after rain/wash… but wet still on 3rd day is a bit worrisome.
