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. Attached is a video of the rattle if it would assist anyone in diagnosing the issue. Thanks in advance!

 

Sounds travel around a car in funny ways... and it's hard to tell from the sound file you attached.

You should have someone drive behind or alongside, to check whether something is flapping under the car. There's plastic splash-panels that might be flapping in the wind.

 

Thanks for the response, Jim...should have known a Saab guy would be the first to respond. My username is MySaab7 everywhere else in the world (TSN, Saab Central, etc., etc., etc.). I'll do some digging around and see if I can narrow down the source of the noise...would like to at least have a better idea of where it's coming from myself before taking it into the dealer. Thanks again!
