Problems with hood at high speeds

Does anyone else have issues with their hood looking like it's going to fly off when driving at higher speed or against the wind?

What year is your ‘Stang? How many miles on the car, and has it ever been in an accident?Is the shaking of the hood mostly at the front or the back? Has it always done this?

No, I have not noticed this on our 2015 at all......have you checked when the car is in the garage how much the hood might flex if you pull/push on it? You might need either the latches or the hinges adjusted.......I do think that the hoods on the 2015+’s are aluminum, which will flex a bit more than a steel hood, but still, ours does not move noticeably even at triple digit speeds......

When parked everything looks good. I recently put a new hood latch on and it's solid. Everything seems to be aligned properly. I guess its and aluminum thing. Still I thing I'm going to get some hood pins just to be safe. Lol

Trust me it's not something you miss. I need to check everything very carefully and make sure nothing is wrong or out of place.

My first generation Bullitt does the same thing. On that car, I believe that the problem is the bump stops that support the outer edges of the front of the hood are out of adjustment and are allowing the hood to flutter during higher speeds or even strong headwinds.

That's exactly what's happening. So to fix that should I adjust up to make it tighter or down to make a smaller opening for air to get threw?

Well, in my case, the bump stop on one side needs to be adjusted up, so that the hood will rest on it to keep everything solid across the front of the hood.

I must caution you, that if you adjust those bump stops too high, you will run the risk of the hood latch not securely latching, which can result in the hood flying open at a most inopportune moment.
So that is something that you absolutely want to do correctly.
The hood should just rest on those bump stops, when the hood is fully closed and the latch is completely engaged. They are there to act as a resting point for the outside edges of the hood. They are not intended to be shock absorbers, or anything of that sort.

If you put a couple of soft pieces of clay on top of each bump stop, and then close the hood completely, the thickness of each piece of clay should give you a good indication of whether the bump stops need adjustment, and, if so, by how much.

My hood on my 2014 GT did the same thing the cause of it was the underbelly shield for the oil and filter was loose causing disruption to the hood at high speeds.

I just saw where the 2020 GT500 has hood pins because Ford noticed that the hood starts to rise at high speeds and they needed the pins to keep it down. Could be that all Mustangs will do this at very high speeds and they finally figured that a car that can do 200 MPH should have them.

Thank for all the input. I'm going to check the splash shields and I'm definitely getting hood pins.

I bought my 2017 new, and it has always had a lot of hood movement at high speeds. It seems to be adjusted properly, and all of the underbody aero pieces are in place. Under the right circumstances, wind will cause a lot of movement as well. I've considered putting hood pins in it, but haven't done it... yet.
