Car Vibrates at 80mph+

[96Coupee]

hello guys!
First id like to narrow out some things so you guys can help me out.

2015 Honda Accord 75k miles.

my issue is the passenger side seat and dash vibrates only at about 80+ mph it starts exactly when I reach 80 mph and then continues.

I have just done the following:

Rotated Wheels
Balanced the wheels
Alignment is fine
tires have about 2k-3k

I have tried anything to fix but still it has vibrations. I don't know what else can cause the vibrations.

please help. could this be the cause of the front passenger side strut being blown? or rear multi link suspension? please anything can help!! it's annoying

Hrm, those tasks you listed would be my first guess too..

How bad is it shaking? As in making noise or as in free back massage?

On a car that new I'd really doubt suspension problems, what brand and type tires? Even if it's been to a shop maybe lift each wheel and carefully inspect it for ballooning or something.

If you went to a shop and they have any sort of warranty on the balance/alignment, ask them to confirm the shaking at 80mph and see what they say.

Axle? Motor mount maybe?
