2025 Mustang GT coupe vibration at freeway speeds

[Louis-Stang]

What model and options does your car have?

Mine is an automatic 2024 GT Premium with the Active Exhaust, upgraded Brembos and the 401A package. It has 2,265 miles on the odometer. Noticed the vibration at around 750 miles. Had my tires rebalanced and it seemed better but 1,500 miles later the vibration is back.

Wow, thats pretty bad if you can feel drivetrain vibes with a 3.15.

You mentioned tires. Can you describe your vibration? Is it a rumble/roar/buzz that reminds you of something similar to an airplane propeller? Or is it a bump, or a bounce or shake or shimmy? Sorry for all the descriptors, after years of trying to get a handle on this problem online you make up some new terms If it’s the latter it’s tires or wheels or something on that end.

Mine with the 3:55 is more of a rumble buzz type situation, you can hear it and feel it.

Sounds like drivetrain. The thing will fool you when you’re trying to tweak it out too, sometimes you think you’ve made an improvement when you haven’t. You figure that out a few days later

i don’t feel the car shaking . The rear view mirror shakes at highway speeds. The faster I go the more it shakes. It’s more like a tremble. If I put my hand up to the ceiling around the mirror, I can feel the ceiling trembling. I don’t feel the tremble when I hold the steering wheel.

if it’s not an oscillating bump at around 15 to 20 Hz, and more like a rumble around 50 Hz it’s most likely drivetrain.

Mine is the same way but its not the whole car shaking, it feels like its buzzing more so and its literally audible.
Definitely in my opinion and driveline issue.

I would definitely try to find a cooperative dealer, depending on where you are. If you get frustrated with that approach, you can try to improve it yourself and I can talk you through how to do that. Doing work like this will not void the warranty, because if you keep good records, you can always put it back exactly factory, and no one will know.

I have the same car as OP except for PP and there is zero vibration from slow to "very very fast". I have OEM Continenal tires and 3300ish miles. FWIW.

Hi, I mentioned it in another thread, it's live here. I'm having the same problem on a Dark Horse 2024 on EU, they changed my driveshaft at 4000 miles , the vibrations are still there, it only changed a little after the change, but issue persisting. I will keep you posted, i go to next service check.

Brought mine to two different dealerships. Neither dealership came up with anything. One dealership blamed the continental tires.
