2011 Ford Mustang

The Office of Defects Investigations (ODI) analyzed complaint data provided by Ford as well as complaints submitted to ODI from consumers.In total, there were 364 unique reports indicating various shift quality issues while driving.Ford identified several factors that may contribute to shift quality concerns in the subject vehicles, including cold transmission, clutch stay-out at high engine speeds, gear clash or grinding, and gradual loosening of clutch plate bolts in some early production vehicles.The largest percentage of complaints indicated higher than expected shift efforts in cold ambient temperatures.These complaints were related to transmission fluid viscosity and the higher shift efforts resolved themselves with the drivetrain warming.Ford published technical service bulletin TSB 11-3-18 to inform technicians that a lower viscosity fluid was available for use to address the cold shift issues.The clutch stay-out condition typically occurs at engine speeds greater than 4000 rpm.It does not prevent the selection of any gear, but may delay clutch re-engagement depending on how long the driver maintains the higher engine speed.Ford identified rotating inertia of the clutch components as the root cause and replacement clutch pedal parts were made available under Ford TSB 10-19-4.A number of reports alleged increasing difficulty selecting gears along with gear clash or grinding.Grinding or notchy gear shifts may be caused by gradual loosening of clutch plate fasteners, which is promoted by certain aggressive shifting.This condition is progressive in nature and initially results in symptoms related to shift quality/feel.Clutch plate bolt loosening will not result in inability to select any gear unless the progressive symptoms are ignored until complete clutch failure occurs.ODI?s analysis identified only five complaints alleging an inability to shift into gear due to loose clutch plate bolts.None of these resulted in a stall and gear shifting could occur before engine start.A revised fastener was designed and implemented in production and is available for service through a special service message.There is no indication of loss of motive power or unreasonable safety risk associated with the alleged defect in the subject vehicles.This preliminary evaluation is closed.

This is a common issue with these S197 Mustangs. The steering position sensor failed. While driving, this can cause the "Service Advancetrac" warning to come on, meanwhile the wheels spin at different speeds as the car attempts to correct a low traction scenario that isn't happening, causing the driver to crash. This caused me to temporarily lose control of my vehicle. Luckily I didn't hit anything. The sensor itself can be replaced for $20-$40, but Ford has sealed it inside the EPAS system, making it non-servicable and escalating the repair cost to over $1300.

Ford and Lincoln vehicles equipped with wired keyless entry keypad systems and accessory wireless keyless entry keypad systems may or may not come with a wallet card containing the master code. Unlike the integrated wired keypad, the accessory wireless keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool or from the label printed on the body control module (BCM). The Factory Keyless Entry Code application within the diagnostic scan tool will not provide an applicable master code for the accessory wireless keypad. If the wallet card for an accessory keypad is not available, the "Wireless RF Keypad Diagnosis Guide" can be referenced and provides direction on how to retrieve the master code. This guide is located under the Workshop Manual tab > Accessories > Installation > Wireless RF Keypad Diagnosis Guide > PPT C > Step C2.<br /><br /> Note: The only available keypad for some vehicles from the assembly plant is the accessory wireless keyless entry keypad. The integrated wired keypad cannot be installed on vehicles not equipped from the factory with a wired keyless entry k

All accessory stick-on keyless entry keypads come with a wallet card containing the master code. If the accessory keypad was factory installed, this card will be placed in the glove box and should be handed to the vehicles owner during initial delivery. Unlike the integrated (wired) factory keypad, the accessory keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool. If the wallet card for an accessory keypad is lost, follow these steps to recover the code. Dealer Key Code access is granted through the Dealer Program Enrollment System (DPES); dealership management can authorize users. The authorized user must go to FMCDealer.com > Parts and Service > Parts Product Line Information > Keys/Entry Devices > Aftermarket Keyless Entry Keypad Code Access. Follow the instructions on the screen to obtain the master code for the accessory keypad.

Some 2011-2024 Mustang and F-150 vehicles equipped with a 5.0L engine may exhibit a tick tap and/or typewriter ticking noise at idle after an engine oil change. It is often referred to as typewriter noise because of its similarity to the sound of a mechanical typewriter. The noise in question may be heard on some engines when engine temperatures reach 150°F (65°C) or higher and engine speed is at idle up to approximately 1700 RPM. It can typically be heard at the front wheel well and is often isolated to the transmission bell housing or oil pan area. The typewriter noise tick rate can be faster or slower and is not detrimental to the engine function or durability and has no short or long term effects on the engine. This an operating characteristic of the 5.0L engine and no repairs should be attempted. This information along with an example audio clip has been added to the WSM Section 303-00 Engine System  General Information > Diagnosis and Testing > Engine > PPT F > Step F2.

Certain 2005-2014 Mustang, 2005-2006 GT, 2004-2011 Ranger, 2006-2012 Fusion and MKZ/Zephyr, 2006-2011 Milan, and 2007-2010 Edge & MKX Vehicles Driver & Passenger Airbag Module Quality Control Inspection REASON FOR THIS SUPPLEMENT • Updated Ranger Technical Information to include images of a pass and fail airbag inflator inspection for 2007-2011 model years.

For 2000-2024 Ford and Lincoln vehicles, swapping a module from a vehicle for diagnosis purposes is likely to cause errors and is not recommended. It is also not recommended to order a replacement module using a vehicle identification number (VIN) from a different vehicle. Most modules on these affected vehicles are VIN/vehicle specific and hardware variations between modules do exist. Swapping a module from a vehicle or ordering a module using a different vehicle/VIN can cause ineffective repairs and additional vehicle down time. Make sure all appropriate Workshop Manual (WSM) procedures are followed when diagnosing the condition prior to all module replacements and only order modules using the correct VIN.

Certain 2005-2014 Mustang, 2005-2006 GT, 2004-2011 Ranger, 2006-2012 Fusion & MKZ/Zephyr, 2006-2011 Milan, and 2007-2010 Edge & MKX Vehicles Driver & Passenger Airbag Module Quality Control Inspection: Ford Motor Company has determined that some vehicles claimed by dealers as repaired under Takata Airbag Safety Recalls 15S21, 17S42, 18S02, 19S01, and 21S12 may not have received the claimed repairs. The propellant in certain Takata airbag inflators can experience an alteration over time with exposure to certain climate conditions. A combination of time, high temperature fluctuations, and humidity contribute to the degradation of the propellant in the inflators. This degradation can cause the propellant to burn too quickly, creating high pressure inside the inflator, and in extreme cases causing the inflator to rupture in the event of a crash necessitating airbag deployment. A ruptured inflator can send inflator parts toward vehicle occupants resulting in serious injury or death.
