Vibration

[24VertPP]

that is interesting. Is your dealer willing to do some trial and error with this?
It doesn’t seem like mine is really interested much. Idk.

To be determined. I have another visit scheduled. I will update as I get more info. I do have a live, recorded, graph from a NVH sensor and software (pico scope) that directly relates the front and rear tire speeds to the oscillating vibration intensity. The g force sensor was mounted to the body where the left front seat frame bolt goes. This is also how I diagnosed the out of balance driveshaft.

Nice. Well keep us updated please.

Nice.
I was going to suggest that.
As someone who seems to be a magnet for brand new cars with vibration or tire wear issues I feel your pain.
I had a Chrysler RWD with intermittent vibration issues. No steering wheel or "in butt" vibrations just shaking.
After replacing you name it, the problem turned out to be a highly intermittent sticking front caliper.
Problem solved by accident when caliper leaked and had to be replaced. No more vibrations.
That was back in the 80's.

These days chassis ears are your best friend.

A dial indictor on the end of the axle. Dealer should be able to preform. Even though you paid big bucks for someone to do their job doesn't mean things are good. Other option is reinstall what others have suggested. A vibration as you describe will cause other problems later on. Wish you the best in solving your problem.

this would require either a setup on a bench or hanging the car in the air and mounting a dial indicator properly while the axles are installed and rotating.
I have been a tech and service advisor in a past life x 10 years. I have rarely seen such precision or detail done.
unfortunately, I have little hope of my dealers capability.

a poor man’s run out / out of round check - affix a solid rod to somewhere solid, perpendicular to the rotating mass you’re measuring. Rotate the assembly with rod just barely not touching. If you get contact you may very well have an out of round component. It’s not precise enough to be a diagnosis, but it’s accurate enough to suggest if you should pursue it further.

They’re only allocated so much money to troubleshoot an issue and repair it. IF the first attempt at repair didn’t succeed, they need to get approval from Ford to go further. If that didn’t happen, the dealer and tech have zero incentive to work on your vehicle.

IOW, don’t leave it there, they’re not doing anything.

So then what do I do? Try another dealer or just deal with it?

I’d get it back, and try another dealer. I’d give it 2, maybe 3 tries and if no resolution push for a buy back. These types of problems require actual troubleshooting where no DTC is present. I’m genuinely surprised they didn’t ask you straight away for a code ;-)

I’ know there’s techs on here with their own Mustangs and I’ve heard time and again how great warranty work is but when you have a vibration, that seems to evaporate. And be prepared, the first thing anyone is going to want to do is tires, balance, etc. It’s’ a very, very frustrating situation.
If it were me and a 2nd dealer couldn’t fix it I’d ask for a write up and request a buy back and if that didn’t work, I’d trade it. Life is too short to deal with issues like this.

I just sat down with the Service Manager. He is going to get the field engineer involved.
Man, it sure seems late for this but I’m glad someone is finally doing this.
They are going to let him take a look at things before any more parts are replaced or swapped.

The Ford customer service rep I spoke with recommended I purse buy back or replacement.
I also spoke with a lawyer yesterday who suggested that I go through the warranty manual and check all the boxes regarding Fords warranty procedure. He said that he has NEVER had a client return to him for Lemon Law claims through Ford when those steps were followed.
Unsurprisingly, I had already done everything but contact the BBB auto line claim team. That is next.
A Mustang that vibrates down the highway is not a Mustang I want to own. If the car cant be fixed, then I’ll aim for replacement of the vehicle and pray that it doesn’t have the same issue.

Following, having the exact same issues after taking the vert on a few hundred miles of rough roads during a road trip. Have every option and every package. Race red, NPP, AVE, 401A, PP, Magnaride. LOVE the car (although miss the PP rear spoiler). If they can figure out your issues, it would GREATLY help me with mine. Would hate to have to do a buyback or replacement and lose the after market PPF, ceramic coat, windshield tint $6400 lot of money to lose. also my daily and Ford doesn't give out loaners for warranty work, which is ridiculous imo, have to pay for a rental. Are you considering just taking the buyback or replacement at this point since it's been so long? Does a buyback give your full money back that you paid initially?
Please keep us updated!

I am not sure about the buy back option yet. I’m hoping that it can be repaired. I’ll keep you updated here.

The dealer swapped out the g-force axels for the factory axles and said they felt it resolved the vibration. I test drove the car today and it did NOT fix it.
not sure about next steps now

Well glad to see I’m not alone. Bought a 24 GT in Oct if 23. At 70 it starts to rumble and you can see the rear view mirror shake like crazy. Can also feel it in the windshield. Took it to dealer 2 times. First they replaced the rear mirror but did nothing to seek out the cause. I paid for them to check balance which they said was spot on. Second they said they couldn’t reproduce. I called Ford after watching the mirror fuzz out on the drive home. Wasn’t much help. I’m going to try another dealer at some point or just get rid of the car. It’s so disruptive and annoying for the price! I don’t expect perfection but I do expect to be able to figure out what car is behind me while driving!

 

[ugasouthernpride]

Dang. Is yours a coup or vert?

 

[Idle0024]

I feel light random vibrations on the steering wheel while on the highway but is not heavy or enough to bother me. My concern is that it gets worst over time. Car only has 200 miles, 180 of which are mines.

 

[Murphstang]

Coup. No performance pack, has the active exhaust. Maybe 4500ish miles now.

This appears to me like a dynamic balance issue. It may not be applicable to every dealer, but few lube and tire men know how to use a tire balancer correctly. It sort of reminds me of the old JC Whitney level style balancer. Fine for static, darn poor for dynamic balance! Heck, even the local Discount tire gets it wrong sometimes, and they of all people should know what's up.

About 5 years ago, the same Discount Tire Store remounted another brand new tire because they couldn't dynamically balance the first one. Lousy deal, but it does happen all too often.

One more thing. If you catch any tire man pouring glass beads into a tire, GO SOMEPLACE ELSE!
