Took my EX-L in for the service appointment on Monday, 1/8. The first adviser I spoke with said he had a women with an 18 Accord in on Saturday with the same issue and Honda didn't have a fix. When I explained to the second adviser that I called Honda CS and had a reference number they insisted on keeping my EX-L to test and provided me with a 18 LX loaner. As I drove the loaner I did not notice any hood flutter??
Today they confirmed the hood flutter and after talking with engineering at corporate, they adjusted the hood dampers, which they said were not making contact with the hood thereby causing the problem.
The hood dampers/grommets are two rubber cylinder like, on each fender approximately 15" back from the front of the hood screwed into each fender assembly. Turn them clockwise to lower them or counter clockwise to raise them. In my vehicle they were not touching the hood thereby allowing the hood to flutter up and down. My EX-L is serial number 20956 and my loaner was 42069 I suspect early production may be more susceptible to this problem and Honda QC has now figured it out, hopefully.
Anyone with this noticeable problem may want to consider this adjustment.
