Spideync Posted August 21, 2022 Share Posted August 21, 2022 I have a 2005 Highlander V6 XLE and a month or so ago it started making this loud buzzing sound on start up. If car has been sitting in hot sun loud usually doesnt appear. Sometimes after startup if sound didnt occur it will occur in first 5 minutes of driving. Sound usually lasts no more than 10 seconds. I have recorded it finally and adding a synch link to the movie file to see if anyone listening to this can tell me whats up. I guess I can go to dealer but unless technician who has heard it before hears it I am sure they will want to tear open the dash etc. Sound from Highlander.mov here is sound file Quote Link to comment Share on other sites More sharing options...
