I have a 2011 Kia Optima and am experiencing an annoying flutter (sounds like from the wheels or tires) at highway speeds, 65-80mph. Has anyone else experienced this? dealer says rotate and it didn't do the job
Are you driving with one or both of the front windows partially down or the sunroof open part way?I have noticed that in either of those situations the cabin pressure "flutters" and is really annoying! If that is not the case, have you tried walking around the car and maybe tapping on trim and guards to see if you can find the culprit? Good luck, hope it's something simple like a busted rivet or a piece of trim come loose......keep us posted if you find anything!
