I have a 2018 Accord Hybrid Touring with a little over 10,000 miles on it. Over the last couple of months, a rattle has developed and it sounds like it's coming from the driver-side area underneath or behind the dash. I've read a number of posts citing an issue with the rubber strut cover, but I removed those and there wasn't any difference. The rattle sounds like very thin plastic fluttering in the wind and it only occurs once I approach highway speeds in excess of about 55 mph. Any idea where to look or if there's something common that I should troubleshoot? I'm hesitant to take it into the dealer without doing my homework, as I have no doubt that they won't be able to replicate the issue even though it occurs nearly every time I drive the car. I have a video of the rattle if it would assist anyone in diagnosing the issue. Thanks in advance!
