Mine goes in Thursday. I'll update with results.

i'm still a little hesitant for this whole process. seems to be a mix of different parts in order to resolve, multiple visits, lost days, and a lot of patience.

You've pretty much summed it up... But you need to at least bring it in and let them and Ford Service here document it for you. What if down the road the vibes start killing our transmissions? Need to have a way to protect ourselves as this is very cost prohibitive repair if it happens just outside of warranty. I know it won't be from abuse on my end. Other than an occassional romp on the throttle, I drive mine like it's made of glass. Never had even one launch from a standstill, never even one burnout, and it never will.

Yep. At this point the dealer has had the car almost as long as I did before taking it in. Frustrating for sure. But the vibration is severe enough that I can't live with it. I figure TSBs are an unfortunate side effect of a performance car. It's just that when you have a luxury performance car (at least in my Cadillac experience) the service is better and faster and the loaners are more fun. Ford is simply not there in terms of service. I'd still rather get the car right, then enjoy it.

16 GT PP here.

Mines been in the shop 5 times for this issue. Alignment, balancing, checking torque on bolts, DS replaced and they currently are looking it over and have no resolution yet. At what point do I lemon it? Speakers replaced, light switch replaced, buzzing and rattling all around and I've only had it about 90 days. I'm just tired of dealing with it and just want it gone at this point. Should I call Ford first to see if they'll take it back or just go through the lemon law process?

Has anyone in NJ been successful at getting their car fixed? If so, please send me a PM where, dealer or driveshaft shop?

My 2016 GT has had both rear tires replaced, in twice for a drive shaft replacement. First new shaft was damaged and a 2nd one had to be ordered. New drive shaft replaced but still have the vibration between 50 and 75. Starting to wish I had purchased a Camaro or another Challenger. Dealership has been easy to work with but I cannot believe that the engineers at Ford cannot figure out what the problem is with these vehicles. I guess it is time to start a claim against Ford and give them one more shot at repair before I ask for my money back.

Contact the BBB (fill out the form on their website) & send out the LL form from the back of the LL booklet you got with the car (1 copy goes by cert. mail to Ford, the other to the FL AG's office).

The process goes fairly quickly & smoothly if you've read & understand the rules/criteria and supply the required documentation.

It really is surprising to me how with all the warranty claims for this issue that the engineers have not instituted a production change to fix it and come up with a fix for the vehicles already in the field. Seriously.... I'm sure there is someone in Dearborn who looks at the frequency of warranty claims on certain parts...? Or do they just not care?

I would think someone is tracking this problem, they just might not be the ones who care.

OK I know it is not the same car but the S197 I traded had bad vibrations too. I put a Ford racing 1 piece driveshaft in it and the NVH was 10X worse. I took it back out and put the two piece back in. This weekend I installed that exact driveshaft from my car in a buddies 2011 GT and it was smooth as butter. The rear end in my 197 had been rebuild and ALL of the internals were replaced. I think this issue is in the tranny myself... It has been an issue since they went to the Getrag.

Still waiting to hear back from my Ford Service agent. No reply in a couple days. I'm not her only customer, but I gotta be one her most polite and patient, maybe that's my problem. Maybe she's working on getting another dealer with the vibe analyzer or maybe an FSE. We will see... It's OK, only the car I worked 20 years to get....

Yea.... Who and where....

I emailed Ford (William Ford and 2 other top level Executives) - you think they gave a shit? Not one single response and yes, the email addresses were valid.

You know where I should forward that same email? To every single Ford employee email address I can find, eventually it will hit a nerve.

Or better yet - why not contact your local news organization's investigative team and give them the run down on how this issue can't get resolved AND the internal Engineering fix is to place a .10 cent HOSE CLAMP onto a $30k+ vehicle's driveshaft as the solution.

If an f'n driveshaft is OUT OF BALANCE (because the Engineering fix with a hose clamp places it "in balance") - the same driveshaft that is SUPPLIED BY A DRIVETRAIN VENDOR - then FORD should be going back to the Vendor and saying "WTF, you're causing my Company PR issues, irate Customers, sales, loss of labor hrs and warranty monies AND you need to figure out WHY the F your company can't produce a driveshaft and matching front/rear flanges that ARE properly balanced".

And if it's NOT a Vendor issue, then YES, one would expect the Ford Engineers to come up with a revision to "X" so that the damn car is not constantly being returned to the shop for the same damn reason - even AFTER it's supposedly been fixed with a freakin hose clamp.

I can drive my 22yr old Cobra from 0-100 and there's NO driveline vibe AT ALL... and that's with upgraded 3.73 gears, a full length aluminum driveshaft and a slew of other mods. Yet a 9 month old current year production vehicle manufactured with better technology from Ford has been into the shop for nearly 4 months out of my ownership (that's how many days in TOTAL between all of the damn visits and the many weeks it went back and back and back and back again) STILL has a driveline vibe even AFTER it was again recently fixed.

It's a joke.

If Ford wants the PR for their product line - they're getting it.

I tell everyone that this Mustang has been THE WORST car purchase I have ever made - even told the Regional Ford Case Managers the same. I told them the Customer Service at certain Dealerships SUCKS, the Quality Control of the vehicle is horrible at best and that the Engineering Department NEEDS to come onto this site and READ the BS everyone has been putting up with regarding the driveline vibration issues.

I even told my CSR, my last purchase was a 2011 Hyundai Genesis Coupe 2.0T - bought the car brand new. It only went to the Dealer for scheduled OIL CHANGES and 1 alignment. The only things that were replaced on that car were TIRES, WIPER BLADES and BRAKE PADS - in 85k miles. Hyundai treats their customers better, their Service Centers are better and their Techs do the job right the first time.

The above is coming from a true Ford Enthusiast too. I've owned (19) Mustangs to date, (2) Broncos, (1) 07 Mercury Milan, (1) 04 Explorer and come from a family that owns multiple Ford vehicles too.

I have been around, gutted, rebuilt, bought, sold, traded and modified Mustangs since 1990 - a driveline vibration is f'n obvious. I don't know who's on Ford's Engineering Team, but hell I'll challenge them to a blind folded test drive and I (as well as ANYONE else on here) can pinpoint the exact rpm/speed at which the vibe is present. You also don't need a vibration analyzer tool to say "oh yea, psssst, hey there Ford Tech, the vibe is coming from under the car".

The TSB solution is a f'n hose clamp for a FIX? Are you kidding me????

Here's the bigger question:
Since the driveshaft is tied to the rear and the transmission - I want to know what mechanical harm is being done to the rear, trans and engine with a constant vibe - since most of us are driving in excess of 60-65mph during our daily commutes.

Who can answer that?

But it happens to the automatics just as much... It could be a lot of things and a combination of things which is why it's so hard to pin down. But, the general troubleshooting scenario is- measure run out at the pinion flange and replace if out of spec. Use the hose clamp method to balance the DS/flange and note where the weight needs to be added. Add washers under the pinion flange bolts closest to the heavy spot on the clamp. Or just leave the clamp on and tack it with a welder if you are worried it will move. The whole thing is BS since these should be balanced at the factory, though.

10 cent hose clamp fix is still holding up and I'm vibration free. This is a driveshaft issue.... not a rear or trans issue. I'm an auto as well.
