Toyota highlander wind noise
When drive my Highlander above 70 mil/h specially on highway I noticed high
wind noise. I checked all resounding of windshield etc but didn't observe any
open part. doors are well closed, no accident and nothing replaced. All parts
are on original condition.
If the vehicle has a luggage rack move the froward crossarm as far back as possible. Try closing a dollar bill in the doors and see if you can pull it out easily, if you can then the door seals are collapsing when they make contact with the door, sometimes you have enough door adjustment to temporally fix this other times you will have to replace the seals. Make sure you don't have any loose trim pieces, some of these can move at high speeds and cause a wind like noise. HTH
You didn't specify what model year. If under warranty, have the dealer check it out for you. Like tennisshoes said, it could be a seal or I would say even the windshield seal itself.
