TSB & FIX: Hood Flutter Shake at Highway Speeds

[inthecabin]

Try preloading the hood by cranking up the 2 rubber hood stops equally in the front. Probably just a full turn each.

It’s really an old school problem seemingly, but that’s the old school fix…

I hope this helps..

Also if one side ends up higher then adjust low side to match the high side, also if this scenario happens then you probably found the problem.

Good luck!!

I did not notice it at first but after reading an owners' review, I did identify a noticeable shake in my Maverick's hood at freeway speeds. I saw that this was a reported problem on other Ford trucks (mainly F250) when I looked deeper into it with some people reporting no hood shake at all. Has anyone else who drives a Maverick regularly experienced this as well?

The new Honda Accord I test drove had hood flutter at highway speeds.
I’m thinking this is just going to become part of the new norm for new vehicles with lighter parts for fuel economy gains.

I haven't looked yet but I think something like this will fix it. I can tell towards the cabin that the hood is perhaps sitting an eighth of an inch below the side body panels.

when I hear this makes no sense. Do you work for Ford? Or know the margins on a Maverick? Because the Maverick I’m sure they would not be building if Ford was not making money. Also they have had other cars that were even cheaper than the Maverick made at the same factory like the Ford Fiesta

We’ll see.

I wonder how hard it would be to reinforce the trailing edge of the hood by bonding something to it (thinking carbon fiber plate) and what epoxy would be right for this use…

How would a under the hood insulation, blanket or whatever they call it help? I would think it would add a small amount of weight to the hood and possibly break up the air flowing through it. Just a thought.

Something like this will probably be the fix. Given that Ford is likely trying to cut weight and cost by using aluminum, gluing on a stiffening plate or rod is an easy and low cost solution.

I think most manufacturers use aluminum hoods, BMW has used aluminum hoods for many years and both of mine have them with no flutter.

I had to replace the hood(steel) on a Ranger. The replacement did not seem to make good contact with the weatherstrip at the rear edge of the hood. The hood flutters in a similar fashion in some situations. The hinges were mounted with adhesive to the firewall from the factory. No bolts. I think the hinges need to be moved down a bit, to tighten the hood against the weatherstrip. The hinge mount plates have a dimple where holes can be drilled and fasteners installed to bolt the hinge to the firewall. Breaking the adhesive and moving the hinges down and installing sheet metal screws would handle my problem, but it is not so bothersome on a 30+ year old truck. It may be a possible solution for Mavericks, while the rubber inserted into the weatherstrip is a lot cheaper(labor time) may work too.

The hood shake I noticed happened at ANY speed. Just pulling out of the dealership I noticed it instantly. There must be an adjustment that can help this issue since not everyone has this problem.

Same.. have had Mercedes, Porsche, and Genesis with aluminum hoods and no issue. That's a different price category, of course, but aluminum doesn't automatically mean hood flutter.

I will say that the BMW’s have padding under the hood like many people have said their other cars/suv or trucks have that as well. Seems like that might be the final fix.

I test drove one last week. Going over rumble strips at 5-10 mph done the same thing.

Has anyone read the OP's #2 Post at the beginning of this thread? It seems to me that Ford has a fix for it already in the bag. I don't really understand why all the remanufacturing the hood and reinforcing would be necessary. Am I missing something?
