Vibration between 50 & 70 mph

[MikeD1]

378 in total wow that's small number compared to total production run of 2015 Mustang and 2016 still in production. You're over thinking it by a lot it's big number because your car having a issue.

Est of 2015 production run 150,000 now 378 very small %.

If it was happening to your car, you'd be singing a different tune !

Also, '15 production run was ~100K, not 150K.

Of the 378 ppl on this forum alone who responded to the pole, 166 have (or had) the issue with their cars. There are similar threads on every Mustang forum + if you factor in something for the clueless ppl out there who haven't complained because they don't notice or are oblivious or bought the dealer "oh, they all do that" line of BS some dealers dish out then IMO the % becomes much more significant.

I got the call today that mine was ready & I'll be going tomorrow to retest it. This is repair attempt #3, this time they had the car for a week. They did not say what was done, but I'm guessing they didn't cap off a week on a insignificant problem !

I have to say after working in a union environment that this is management pushing production through. The workers do what they're told. Management has figure out that it's cheaper to make 'em this way or they would halt production and fix it. Now that's expensive! The workers know what's wrong very well, one from Flint posted on facebook as such. Management pushes out defective product in short sighted chase for numbers on a report.

Have said mine has slight vibration too. Far as I know total production Numbers are not out yet. Again I SAID "EST" didn't say it was 150,000 and again it was estimate.

Seems there are many people on this forum that have a better clue on how to trouble-shoot and fix a drive line vibration than some of the dealerships based on what's all been said in this thread.

Mine is at dealer now. We will see what happens. Been there a week already.

My POV is that it is an issue that should be fixed at the factory, even though owners' cars with the issue are being taken into the dealer. There is no other option for us - we don't send the car back to the factory for a fix.

I don't care how much diagnosis is required, by whom, or with what equipment, or for how long. The point is that if it can be resolved at the factory for cars in production, and then the fix released to the dealers, then everyone should eventually be satisfied.

Now, if the % complaints is deemed sufficiently low, then they are less likely to research a solution, or to announce the fix for retrofit. The same applies if the fix/retrofit costs Ford too many millions.

I suspect that the problem is on their to-do list, or even their "it would be nice to solve" list, and perhaps to be solved by a future model year. Or not.

I checked the torque on my lugs (thank you, Enzo!), and found that the FSE apparently was not aware of the new torque spec (as well as 4 other dealers I called). I retorqued all lugs to 150, but still have the vibration. On a more (hopefully) positive note, I dropped the car off at the dealer for a last try (thank you, Deysha!).

Apparently, despite the car being in arbitration for the vibration, Ford is allowing my dealer to take a look at the vibration and the convertible top rods. Hopefully, they take the first step with the vibration -- that is, admitting there is a problem instead of using the "Jedi Mind Trick".

Here are the results of the torque checks on the lug nuts:
Tire Lug 1 Lug 2 Lug 3 Lug 4 Lug 5
RF 75 100 110 85 90
RR 100 100 80 85 100
LR 120 70 50 70 85
LF <50 65 95 95 110

You’re welcome, Jim05!!

hey Ford is the TSB for fixing this done yet?

if not then why?

A TSB is not done from one day to another, ultimate warrior. As I’ve mentioned before, engineering is aware and working on something. If a TSB is released, it will go to your Ford Dealership and not this thread (unless a member posts it). Please, if you are experiencing any concerns with your vehicle, be sure to get it fully diagnosed at your Ford Dealer.

Mine is at dealer now. We will see what happens. Been there a week already.

Let’s get this escalated for you, amilhazes. PM me with your VIN, dealer, mileage, full name, and best daytime number.

I have not had a chance to get on here over the last week - however I will have some information to post up later today/tonight. I picked up my vehicle on March 2, after nearly a 3 week stay at the Ford Service Center. It's fixed - and it feels and drives better than the first day I took ownership of it.

Stay tuned.....


Also, for those who have legit claims, that have been verified by your Dealer - don't let others in this thread derail it with ill will and non-value added gibberish.


(DEYSHA - thanks for all of your help and getting the issue elevated with my vehicle as you have for others. I know I may have been aggressive in my approach on here with some of my responses - but it was in no way aimed directly at you. It was more of a "hey, you're an insider there at Ford, so let's elevate this to Engineering Team faster since the issue existed on 2015 and carried over into 2016 models." ----> THANK YOU!)

Nice ... looking forward to the details of what fixed yours.

****BAD RESOLUTION TO MY VIBRATION*****

Was escalated to the Regional Customer Service and while they are good at returning email they apparently are not good a forcing a replacement of the two wheels that require 7 ounces of weight to zero balance. Without tires the wheels require more than four ounces.

The replacement wheels cost $1,412.18 which includes core charges, yes ford wants the old parts back so they do not get re-sold. Now you see why they don't want to touch this issue...

Bottom line, I will pursue the Dealer and Manufacturer in CA small claims court, my time and trouble and anguish is worth the maximum $10,000. However, class action against Ford is a possibility if some want to PM (contact) me.

Thanks Deysha for the escalation, guess the western region hasn't gotten the memo on good customer relations.

Ok - this post will contain some important info, basically an outline that will help others with the same driveline vibration issue. PLEASE READ THROUGH! My next post will contain the pertinent info that resolved my driveline vibration issues.

Partial Retraction of my post #962:
I stated in that post where the FSE never showed up at my Ford Service Center on 02/25; come to find out - that was not true, the FSE DID show up to my FSC on the day he was scheduled. I was given misinformation from the FSC Service Writer, who cannot relay information properly to Customers. This issue of the FSC Service Writer's ignorance was elevated by my Regional Ford Customer Service Rep (CSR), hopefully he'll receive additional training. My CSR has documentation and confirmation that the FSE was on site (unbeknownst to me based on what I was incorrectly told).

Note about tires:
Now, for those who have brought their vehicles into their FSC, the vibration is NOT related to the tires, even though most FSC's want to Force Balance the tires. If having a PP equipped Mustang with the Pirellis - AND temps are below 40*, the tire compound will become hard and exhibit some NVH. This is normal, however it is not the source of the vibration. Force Balancing will not resolve a genuine driveline vibration. HOWEVER it is a NECESSARY part of Ford's diagnosis when customers complain of a speed induced vibration.

DO NOT GET DISCOURAGED if your FSC wants to rotate or balance tires - it is usually the initial step in the diagnosis procedure (this has been documented many times within this thread of how many folks had their tires balanced, etc.).

The 55-65mph Vibe:
This is a genuine problem. The car MUST be brought to the FSC for them to initiate diagnosis. If posting here bitching of a driveline vibe or vibration while driving and you're not taking it to your FSC to have it diagnosed, you're really wasting your time and energy posting here. You HAVE to have a claim opened with a Regional Ford CSR to "bump" priority of your vehicle at the FSC and so that the Regional Ford CSR will be your advocate for expedited repair AND communication between the FSC and Ford's Engineering Teams.

FSC notes:
The Ford Service Centers have to follow "protocol" via the available repair resources they have at their disposal. This "vibration" issue has not been documented via a TSB (yet), so the FSC's are at the mercy of Ford and any other available references such as the Ford HOT LINE, the Ford CSR/FSE communication and/or Smart Customers who can supply references such as to point them to this very forum. Getting irate with the FSC Service Writer will not solve anything - they did not build your vehicle, they did not cause the issue - THEY are trying to help YOU, even if it takes weeks on end. If you are short tempered, believe that cussing, screaming and yelling will get you far in this world - you're not going to have any better luck getting the problem resolved with Ford OR your FSC Service Writer.

The FSC must diagnose by process of elimination - you must be patient during this process..

1) If you have a light colored interior (other than Black), request that the FSC install seat covers and paper floor mats to avoid grease/dirt transfer while it's being worked on.

2) If you are anal about your vehicle while it's in their possession, request that it must be parked in their garage overnight, instead of being left out on their lot.

Loaner Vehicle:
If your vehicle must be kept at your Ford Service Center and its your only vehicle - you must request that your FSC supply you with a loaner vehicle - paid for by Ford. If your FSC will not supply you with a loaner and tries to tell you that you don't qualify for a loaner because "you did not purchase an extended warranty", contact your Regional Ford CSR and request that you must have a loaner paid for by Ford. You should be granted a loaner, free of charge (except for fuel costs) for as long as your vehicle is in the shop. It's not your fault the vehicle must be inoperable due to this issue - press (politely) for a loaner, you will get it. If you are granted a loaner, who cares how long you have it, at least you have wheels to get around in the mean time.

Ford Regional Customer Service Rep (CSR):
Ask or PM DEYSHA on here to put you in contact with your Regional Ford CSR. This is the absolute BEST way to get an advocate on your side, trust me. Stay in touch with your CSR via phone calls, voice mails or emails. Even if you don't hear from your CSR, contact them. They will stay in touch or update you, but they have many cases they are dealing with, so again patience is important.

My next post will document what my FSC did to resolve the driveline vibes on my 2016 EB Premium w/PP. My invoice (work order) was open from February 02, 2016 through March 02, 2016. The car was at the FSC for 1 week, then back again for 2.5 weeks. During the entire time my FSC had possession of my vehicle, I had a loaner vehicle from them.

PLEASE NOTE:
The below images are of my actual Ford Service Center invoices. I have omitted the headers and footers that contain personal information as well as Dealership information. I have also blurred the names of the FSC Techs, their Lic #'s and the Service Manager due to privacy concerns. All content as seen is 100% legit and my vehicle is 100% fixed as of March 3, 2016.

Pages 1-10 are what you want to show to your FSC if you have a genuine driveline vibration! There are extremely detailed notes between my FSC, the FSE who came out to the site location AND the Ford Hot Line Engineering Team. READ THROUGH ALL DOCS - it gives a very detailed synopsis of what parts were replaced and the final resolution.

Believe it or not, once the FSE and Engineering Team requested the tech to "neutralize" the ENGINE and EXHAUST, it was relayed by my FSC that once those steps were accomplished, the driveline vibration was no longer present. THIS IS A VERY IMPORTANT STEP THAT NEEDS TO BE BROUGHT TO YOUR FSC's attention!

My Mustang has NO NVH at all after picking it up. The only things I feel or hear are the normal "buzzy" 4 popper engine and road surface noise while driving. There's absolutely no vibrations while driving in ANY MPH range - all the way past 75mph - its SMOOTH! In fact, the car feels 100% better than when I had taken initial ownership!

The neutralization of the engine and exhaust (along with the driveline parts replacements) is the definitive fix!

I can also say that my Ford CSR has elevated this issue within Ford, within the Ford Engineering Team and it has reached the upper levels within Ford as well. I was the advocate for the members of this site - and pushed hard for such elevation and documented every step of the way to my Ford CSR what was going on, how as a Consumer and buying a brand new Ford Product that I was extremely disappointed in the QC of the vehicle. I was told on multiple occasions that my specific case was and is being looked at internally by many "eyes" and it was elevated to many Departments. I can only HOPE that a TSB will be created and released soon - to benefit other Mustang owners as well as the Ford Service Centers.

I hope all of the information I have posted in this thread does help others. If there's ANY questions, POST them here!

^^^ Excellent advise in these 2 threads for any major service issues !!

I got my car back today after attempt #3 by Ford (but try #1 by the selling dealer).
The issue is mostly resolved, I will post the details tomorrow.

Tell them to order a pinion flange, too. Mine had 3 different DS and still was quite bad. They replaced the pinion flange and did the on car balancing and that fixed it.

Hi guys, speedfrk that sounds exactly right. Remember, that the driveshaft and pinion flange are a matched set! Sending the driveshaft out for rebalancing may in fact (i.e. Is highly likely to) make the problem worse. Ditto for putting in any old driveshaft out of another Mustang where that shaft is not matched to your flange.

If you are having the vibration problem: if you have access to a lift or if you can jack up your car and put it on stands, do that. Examine the driveshaft. See if it wobbles like the other guy on this forum, Either at the hanger bearing, or anywhere else including near the flange at the rear. If it does, the shaft probably has to be replaced. With a matching flange.

Next look for yellow paint dots on the driveshaft and on the flange. Remember, the driveshaft and flange are a matched set! A given amount of runout at the flange is offset by a given amount of imbalance in the shaft. However, they have to be aligned to cancel each other out. Thus the dots. These are supposed to be aligned when the car is assembled at the factory. If they are not aligned, that's probably the reason why you have a vibration. Unbolt the driveshaft at the flange and rotate the driveshaft until the dots align. Test drive car.

Mine begins the journey tomorrow to fix this problem. I have to say the vibration in mine is about a four on a scale of 10. It has to have some other issues fixed first however that are a little bit more pressing. I'll keep you updated

I said it in past post vibration may not be driveline. I just didn't go into detail because people don't believe a tech.
