2012 Boss rear axle/brake noise and tranny leak
What did they do about the fluid leaking from the trans vent? Pretty sure I have this same issue. It's getting on the exhaust and burning off leaving an interesting odor...
Any of this look familiar? https://themustangsource.com/f813/fo...riving-498905/

As far as the trans he showed me where the fluid was leaking out the vent tube on top of the tranny. I let them know that the trans was hard to shift into 2nd when cold and they said they will be replacing the gear oil per a TSB, and making sure the level is correct. They said we will watch the vent for futher leakage.
But then again I only have 2100 miles on the car so far
as far as other issues my control arms are being replaced under the tsb as they are noisy LOL

My car developed a slight chirping noise from the left rear brake/axle area. 
The noise was consistent with wheel revolution and actually got much louder with harder brake pedal application until it actually goes away. We did a state inspection at my work and also noticed a gear oil leak from the trans. I made an appointment with my local Ford dealer...
So by the time my appt came around the weather was warm and the chirping was embarassingly loud, so I knew something OTHER than debris on my brake pad was causing the problem.
The lead service writer had the shop foreman ride with me to show him the noise and he said he will get me when the car is on the lift to explain what he finds. So a hour goes by and they page me, he expained the hub was not pressed onto the axle shaft correctly and as such the whole wheel/tire/brake/rotor assembly was wobbling slightly causing the chirp as the rotor hit the brake pad. They are replacing the left rear axle assembly along with the rear diff fluid (needed to be done at 1,000 miles anyway
)

They said we will watch the vent for futher leakage. BTW I had them change the oil filter only and top off the oil. It only took 1 quart of oil with the filter change...pretty low consumption for 1300 miles!!
Great service for a really dumb issues...

Anyone else out there with bent axles? Beware of the chirping bird sound!

I just got back from the dealer. I tried to plead my case. They said that they have seen enough Mustangs with the same issue and they know why it happens (i.e. track use).
Total cost to have the dealer replace both axles, bearings, seals, etc. is $729.59 (parts only). I'll probably just change out the right side myself and call it good.
On the one hand I'm kind of ticked off but on the other hand we all know that tracking our cars will lead to warranty coverage issues down the road.

Don't do what I did:
1) Bring car in using red key (It's all I ever use)
2) Have brake rotors with obvious signs of high temperatures.
3) Leave on aftermarket wheels with track tires (RE-11's)
4) Leave on caster /camber plates
5) Leave tech sheet from autocross (mini-road course) in the glove box. This was really stupid. I forgot it was in there.
Replacing an axle won't break the bank, but my powertrain warranty is history for all intents and purposes. I can't do anything about that, but I can certainly choose where I buy my next car and won't be from Charles Gabus Ford in Des Moines, IA.

It sounds like CO/ had a bent axle or misaligned axle flange. No idea if he tracked it.
I did a little more research last night and found several threads with owners trying to diagnose a chirping sound that ended up being a bad axle. In most cases the dealer fixed it under warranty.
At my dealer I flat out asked the service guy "If my car showed zero signs of having been driven at all, would you replace the axles under warranty?" He ignored the question and proceeded to explain that the red key shouldn't be used all them time and handed me a printout of the customer track key instructions. I said I didn't need them.
I'm going to take it to another dealer and see what happens.
Other examples of this problem:

WARRANTY COVERAGE
The Boss 302 carries the same warranty as other Ford Mustang models.
This information is covered in its entirety in the Ford Motor Company
Warranty Guide.
The three unique Laguna Seca Package high performance parts (front
splitter, front brake cooling kit, and transmission cooling scoop) are
intended for track use and have no warranty coverage.
Warranty service for the Boss 302 can be obtained at any Ford dealer
nationwide.
Ford does not recommend modifying or racing Ford vehicles, as they are
designed and built to be driven as delivered from the factory. The Ford
Motor Company Warranty Guide discusses vehicle usage and the
installation of aftermarket parts and their effect on warranty coverage.
Please see the Warranty Guide for complete information.
In the event the vehicle is intended for track use, and the loss of
warranty coverage is not of concern, the following vehicle durability
modification is required:
• Ford recommends that you change your axle lubricant and
friction modifier after the initial (first) hour of high-speed
operation or if the vehicle is subjected to track or competition
conditions; thereafter changing the axle lubricant and friction
modifier every 12 hours (under these conditions).
• Ford recommends you change your oil and filter after your
vehicle is subjected to track and/or competition conditions.
Additionally, perform multi-point inspection and the maintenance
outlined in the 150,000 mile (240,000 km) normal maintenance schedule
of the scheduled maintenance information after track use. Refer to
the vehicle service manual for removal and installation procedures.
Replace with Genuine Ford and Motorcraft service parts as needed.
These modifications may not necessarily protect your engine from
damage in competition conditions. Subjecting your vehicle to competition
conditions even with these proposed modifications may render repairs
non-reimbursable under the warranty.
From the Ford Motor Company 2012 Warranty Guide. Apparently we aren't supposed to use our cars as permanent stationary power sources.
WHAT IS NOT COVERED UNDER THE NEW VEHICLE LIMITED
WARRANTY?
Damage Caused By:
• accidents, collision or objects striking the vehicle (including driving
through a car wash)
• theft, vandalism, or riot
• fire or explosion
• using contaminated or improper fuel/fluids
• customer-applied chemicals or accidental spills
• driving through water deep enough to cause water to be ingested into
the engine
• misuse of the vehicle, such a driving over curbs, overloading, racing or
using the vehicle as a permanent stationary power source
Damage Caused by Alteration or Modification
The New Vehicle Limited Warranty does not cover any damage caused by:
• alterations or modifications of the vehicle, including the body, chassis,
or components, after the vehicle leaves the control of Ford Motor
Company
• tampering with the vehicle, tampering with the emissions systems or
with the other parts that affect these systems (for example, but not
limited to exhaust and intake systems)
• the installation or use of a non-Ford Motor Company part (other than
a certified emissions part) or any part (Ford or non-Ford) designed
for off-road use only installed after the vehicle leaves the control of
Ford Motor Company, if the installed part fails or causes a Ford part
to fail. Examples include, but are not limited to lift kits, oversized
12tires, roll bars, cellular phones, alarm systems, automatic starting
systems and performance-enhancing powertrain components or
software and performance ‘‘chips’’

So from what that says, as long as you did not modify the car or race the car under competition conditions you should be covered. This has been debated before, but racing and driver's ed are distinctly different activities.

I'll give the service department at dealership #2 a chance to do the right thing (and win my future business). If they don't come through I'll go back to the first one with my warranty in hand and have them clarify their decision.

If the first dealership entered your problem in the Ford database and associated it with your VIN, you may have an uphill fight on your hands. When the second dealer types in your VIN, they will be able to see the first dealers report and reason for rejection.
Good luck.
Good luck.
