Two days after we purchased our EX we set out on a 3,000 mile trip. During the trip my wife and I noticed at highway speeds the hood kind of bouncing up and down like it was unlatched. This happened mostly when we were passed by a semi on a 2-lane highway. The wind of the semi seemed to be the only case where we noticed it. We stopped two times and checked the latching to make sure it was secure. It was. And then we would open the hood and check the back hinges to see if they were secure. They were. It is strange but now understanding that "the hood is made out of aluminum to reduce the weight but was also designed to collapse inward if a pedestrian is struck by the car to reduce injury" makes sense. It's something we can get used to and should be no problem. Saving money on gas with lighter weight (and presumably safe) materials as well as saving lives with a collapsable hood is very important to me. I can't imagine Honda engineers designing something that is dangerous for the passengers.
3. My hood bounces or shakes excessively while driving at highway speeds or in high wind.
If anyone has any insight on fixing these issues please let me know. The Nav recently disappearing from the gauge has been the most frustrating. I still really like the car overall and am happy about the purchase. Honda Sense and Android Auto has been really useful.
This hood flutter has also been reported on the ‘18 Accord. I had the ‘18 Accord EX and had it. I plan on having the dealer look at it and if necessary open a case with Honda.I have also noticed the hood vibrating, sometimes severely, at highway speeds or when it's windy. Today with a strong cross wind it vibrated so strongly that I genuinely became concerned it might pop up. Even though it usually lasts less than 10-15 seconds, all that vibration must be putting a strain on the latch/screws. I have asked at my dealership if they have had any other complaints about this, but they ignore the question and tell me to 'make an appointment' and have it looked at.
I never took my Accord to the dealer for it, but there is a long thread about it on driveaccord.net. Some have tried resolving it themselves but I think it is a design problem.Was the dealer able to identify and resolve the hood flutter issue on your '18 Accord?
