I noticed this a few days after purchasing the car. it flexes right in front of the driver steering wheel while driving. I look at the opposite side on the passenger side, and did not see any flex at all.

I’ve had my 2018 Sport to the dealer twice for the same flutter without a fix. I have the black accord and it seems much more noticeable while driving with the glare.
There aren’t any adjustable bumpers or dampers on the 2018. The dealer took out 3-4 other 2018 on the lot, ALL with the same flutter over bumps and at the higher speeds. Conclusion is design flaw and have to wait for a service bulletin for a fix.

is this a defect that would require a fix?

This flutter is an unnecessary annoyance. I note it more on the darker colors where reflections are more prominent. It stands out more on touring models where/when HUD is activated and ones eyes are directed to that area. Picked up first touring (1.5) October 14 and it was quite noticeable. Now have a Silver 2.0, and while not quite as noticeable, it's there. Have driven approximately 40 '18 Accords...they all demonstrated this trait.

did you exchange 1.5 to 2.0 as trade-in?
