The below Technical Service Bulletins, TSB for short, were issued for the 2011 Mustang and contain symptom, diagnosis, and repair information for common issues. Click the TSB ID numbers below to see the full TSB, there is also a brief description of the TSB below the number.
Issue
Some 2011 Mustang Shelby GT500 vehicles equipped with a 5.4L engine and built on or before 8/2/2010 may exhibit steering wheel shudder under heavy braking, steering wheel nibble, or a drift/pull condition.
Issue
Some 2011 Mustangs built on or before 4/25/2010, with a manual transmission and low mileage, typically 10,000 miles or less (16,093 Km), may exhibit a clutch pedal Stayout condition at very high engine RPM. This condition will generate a concern of the clutch pedal remaining on the floor during high engine RPM shifts. When engine RPM drops clutch pedal operation returns to normal, but the re-engagement may be abrupt.
Issue
Some 2011 Mustang V6 and GT vehicles may exhibit a fuel gauge indicator dropping from approximately 1/2 to 1/4 full to E, and Message Center displaying 0 Miles to Empty. This concern may be intermittent. Customers may also notice that when refueling, the vehicle takes only 7 to 10 gallons of fuel (tank capacity is 15 gallons). This concern may be due to the Fuel Pump Module (FPM) not drawing fuel from the fuel pick up located in the RH side of the fuel tank, which may be caused by an internal restriction in the FPM.
Issue
Some 2011 Mustang vehicles built on or before 8/16/2010 equipped with a 5.0L engine may exhibit the malfunction indicator lamp (MIL) illuminating with one or more diagnostic trouble codes (DTCs) P0301, P0302, P0303, P0304, P0305, P0306, P0307 and/or P0308 present.
Issue
Some 2011 Mustang vehicles built on or before 8/16/2010 equipped with a 5.0L engine and either a manual or automatic transmission may exhibit the malfunction indicator lamp illuminating with diagnostic trouble code (DTC) P050E, P061C, an intermittent hard start/long crank time up to two (2) seconds, or an idle speed dip, roll and variation in hot ambient temperatures. In addition, vehicles equipped with an automatic transmission may experience an idle speed dip, roll and variation (surge) in first gear coast or during an immediate reverse engagement after starting the engine.
Issue
Some 2011 Mustang vehicles equipped with a 5.0L engine may exhibit premature percent Oil Life and Oil Change Required indications in the instrument cluster message center. The Intelligent Oil Life Monitor system uses information from the powertrain control module (PCM) and an algorithm to calculate the proper oil change interval based on the vehicle operating conditions to provide a maximum oil change interval of 16,000 Km (10,000 miles). However some vehicles may indicate a maximum interval of 8,000 Km (5,000 miles) regardless of how the vehicle is driven.
Issue
Some 2010-2011 Mustang vehicles built on or before 7/26/2010 may experience electrical circuit concerns related to systems controlled by the Body Control Module B (BCM-B) following a battery disconnect. The BCM-B memory retains old circuit diagnostic trouble code (DTC) faults even after the prior repair resolved the condition. Any subsequent battery disconnects may result in the return of the original DTCs and cause the BCM-B to shut down the previously repaired circuit(s).
Issue
Some 2011 Mustang vehicles equipped with a 3.7L engine and 6R80 transmission built from 11/1/2010 through 11/30/2010 may have the malfunction indicator light (MIL) on with diagnostic trouble code (DTC) P0741 stored in the powertrain control module (PCM).
Issue
Some 2011 Mustang vehicles equipped with a 3.7L engine and have an engine build date on or before 2/11/2011 may exhibit a squeal noise from the accessory drive belt during a cold engine start. The concern may be worse during cold and damp weather.
Issue
Some 2011 Mustang vehicles equipped with a 5.0L engine and built on or after 8/17/2010 may exhibit a malfunction indicator lamp (MIL) on with diagnostic trouble codes DTCs P2195, P2197, P2626 or P2629 stored in the powertrain control module (PCM) memory.
Issue
Some 2011 Mustang vehicles equipped with a 5.0L engine and built on or after 8/17/2010 may exhibit a malfunction indicator lamp (MIL) on with one or more of the following diagnostic trouble codes (DTCs) stored in the powertrain control module (PCM) memory: P0301, P0302, P0303, P0304, P0305, P0306, P0307, P0308, P050E, or P2610.
Issue
Some 2011 Mustang vehicles equipped with a 5.0L engine and built on or after 8/17/2010 may exhibit a piston rattle noise in cold ambient temperatures of 10 degrees Celsius (50 degrees Fahrenheit) and below. The noise normally occurs in the 2000-3500 RPM range and will decrease as engine temperature warms up. An update of the powertrain control module (PCM) calibration to reduce intensity and duration of the noise is now available.
Issue
Some 2011-2012 Mustang vehicles equipped with 5.0L engine may have unauthorized modifications to the powertrain hardware and/or calibration which may result in exceeding component design limits. Such modifications could cause damage to the powertrain and/or void the powertrain and/or void the factory powertrain warranty.
Issue
Some 2011-2012 Mustang vehicles (excluding Boss 302) built on or before 3/31/2011 and equipped with a 5.0L engine may exhibit an intermittent metallic rattle or scratching type noise in the area at the front of the left hand (driver side) cylinder head at idle with the engine at operating temperature.
Issue
Some 2011-2012 Mustang vehicles built on or before 9/1/2011 and equipped with 3.7L engines may exhibit illuminated malfunction indicator Lamp (MIL) with diagnostic trouble code (DTC) P0460 stored in powertrain control module (PCM) memory This fuel level indication (FLI) DTC may be a false code generated by customer fueling habits.
Issue
Some 2011-2012 Mustang vehicles equipped with a MT82 6-speed manual transmission built on or before 08/15/2011 may exhibit increased shift efforts in cold ambient temperatures. This is usually most noticeable in 1st and 2nd gears but may also be noticed in 3rd through 6th gears. The increased shift effort may be the result of the increased viscosity of the transmission fluid in cold weather.
Issue
