Just wondering if anyone else has had this problem before... While driving down the highway I noticed that my hood was vibrating pretty badly, mostly toward the back near the windshield anytime I was going faster than around 75 mph. Around 80-85 it gets really bad.. The first time I noticed it I pulled over on the side of the highway to make sure the hood was closed and latched properly, it was. Its not all the time, but its very annoying when it happens.

Yep. But in excess of three digits.

This was talked about by me, couple of years back.

If you've removed under belly pan(s), particularly the larger one under engine, replace it.

Attempt to replicate condition.

At least on the f150s, have heard the fasteners on the belly pan can fall off/come loose.

Definitely check the pan.... I have no vibration of the hood with the speedo buried... If it's not the pan something is wrong in the hinges/ adjustments...

Ill try to take a video of it tomorrow, its bad enough to make me nervous that I'm about to get a hood through the windshield. All the plastic under the car is intact and secure, so its not that.. I have taken 5+ 800 mile road trips with the SHO and have never seen this happen until recently..

I really can't take it to the dealer and expect them to replicate it.. "ya, so when Im doing 20+ over the speed limit on the highway, the hood shakes".... I've checked the hinges and latches, all secure.

jd... interstate speed limit is 75... 10 over is what everyone drives out here at least... just tell them.   We did on a tire vibration at 80-85 on our F250.... got a new set of tires and no questions... dealer did all the tire warranty and negotiation work too!.  No IH close so we had to drive it with them in the truck to show them....

Make them fix it!

I thought 85 was the speed limit in KY back in the '80s.  I had to speed up just to keep pace with traffic, and that was in the right lane.  Cops were passing us in the left lane!

My hood shakes a little regardless of whether I have the weather stripping under the hood or not.  I leave the back off around the cowl along with the engine cover myself.

Interesting to read these reports... i'll have to look closer...
but I have been unaware of any hood vibration or visible lifting from 0-buried speedo... if the bottom plate is installed.
9400 miles on the retainers for the bottom plate... multiple R&Rs! (up to 6 in one day)... still tight and not problems.

+1 I have not noticed any vibration from the hood. I know that my bottom plate is not that tight either. But I will pay more attention next time I'm above 75

found the culprit causing my hood to shake above 80... My girlfriend took my car in a while ago to get the active cruise looked at (another story itself) and it seems the dealer neglected to fully secure the air dam that is bolted to the bottom/back side of the front bumper... as a result, the bumper now has 2 broken tabs and the unfastened air dam is cracked in a couple places. I swear, the more "right" I try and do for this car, the worse my luck gets! I searched wide and long for a SHO with low miles AND a warranty, didn't get a great deal on the car cause it was "the one" I wanted and had the 100k warranty so I justified paying more... Now I have a car with a broken front bumper, NO CRUISE CONTROL, a shaky hood that prevents me from driving at more than 80 mph and it has now developed a weird hesitation at part throttle. Ford claims they cannot replicate the hesitation, even though they rendered the cruise inoperative they say its not their responsibility to fix it..... WTF did I buy a warranty for?
