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!

Post the video of the rattle. Do you have any accessories installed on exterior of the car? With you mentioning it being speed related just wondering if the noise is coming from the exterior of the car.

The only accessories are the mud flaps/guards, which were installed by the dealer prior to original delivery.

Ok, probably not the cause. Looked/listened to your video and really couldn't hear what you are describing (however my hearing isn't the best after 31+ years of sirens & air horns)…. You may want to look at this thread - Creaking sound from HUD display if you haven't already. From the location you are describing the noise coming from it may be the source.

I had this happen to me last summer, when the weather got warmer. I found that 2 plastics parts were rubbing together. I posted on the Thread, and also attached a photo. I was able to fix mine as well.

Did you ever figure this out? I have the same stupid thing going on and its driving me nuts... I just had my dad druve the car so I could sit in the passenger seat and try to figure it out but I couldn't hear it from that side... so i was thinking it has something to do with the passanger seat... but the. Noise it exactly the same and it only happens on the highway above about 60 65 for me...
