2025 Mustang GT coupe vibration at freeway speeds

[LouG]

Just road tested, no rollers. Im trying to get the vibration test results now to see what they came up with.
[/I think I'd insist on going out with the Tech, and seeing if he really thinks the vibometer is accurate.

What a crappy issue. First thing I'd do is take a driveshaft off a Mustang that doesn't vibrate and swap it with yours to see if that'd do it. Really seems like an imbalanced driveshaft to me.

Was exactly my initial thought as well but they said they had it checked for balance. Did they really? That remains to be seen.

Unless I missed it, I didn’t see if you said if you have MageRide or not. I am assuming No. If you did, that would be another variable.

I didn’t see mention of them checking your rotors. Maybe one is warped.

Two words: Lemon Law. Textbook case.

No it's not.

Because?

Didn't someone have a similar issue and some cradle bolts were loose or something?

Lemon Law in CA. if the problem isn’t resolved within 4 visits, or car is in the shop more than 30 days. Or if the problem is a severe safety problem and can’t be fixed within 2 tries. The dealer might be pushing you off so they don’t clock the 4th repair attempt which would allow you to pursue the Lemon Law. But if your car has actually been at the dealer for more than 30 days for the same problem, you can already start leveraging a solution.

Always good to know your rights. Good luck with getting your issue resolved! Hopefully it doesn’t come to legal action.

Someone did have the exact same problem. But I can't remember what it turned out to be. Could have been cradle bolts.

That’s all well and good, but for consumers; or potential plaintiffs, there’s what the law says, and there is how it is applied. If the complaint is objective; something not disputable; you blew an engine, performed all req’d maintenance and upkeep, didn’t abuse the car and it still blew. They repair it, and it happens again. That’s an objective textbook lemon law scenario.

NVH is subjective. Even if the NVH is confirmed by the service department or departments, additional NVH can be introduced by modification, or there could be a very odd out of round/balance condition somewhere in the drive train. Lots of vehicles have NVH - Raptors for example. Getting tires balanced on that truck is an exercise in frustration. That said, it is a safe bet that your performance oriented Mustang has more NVH than say a Lincoln Navigator, and by design. Well, maybe a side effect of that design. This may not concern buyers who come from a performance car to the Mustang, but someone who comes from say, a Lexus might have a different expectation.

Anyway, subjective ‘lemon’ suits are much more difficult to prevail on, often hinging upon whose expert witness can create the better narrative. Your dealer service department has already said that other similar vehicles on the lot behave similarly.

Lemon law suits are challenging and can take a while to resolve so you would be well served to make it your choice of last resort.
