# Service bulletins for the 2011 Ford Mustang

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

63 bulletins from NHTSA, as of 2026-10-19.

- [SSM 54601](/bulletins/11029052.md), 2026-02-27, Service bulletin: ELECTRICAL SYSTEM; STRUCTURE:BODY; UNKNOWN OR OTHER. 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 \(BCM\).

- [SSM 52334](/bulletins/10251951.md), 2024-03-20, Service bulletin: ENGINE AND ENGINE COOLING. 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.
- [22B05 S1](/bulletins/10240415.md), 2023-08-03, Service bulletin: AIR BAGS. 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.
- [SSM 51536](/bulletins/10235153.md), 2023-05-04, Service bulletin: STRUCTURE. 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.
- [22B05](/bulletins/10209374.md), 2022-04-04, Service bulletin: AIR BAGS. 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. Additional information regarding Takata recalls can be found at www.nhtsa.gov and www.safercar.gov.

- [SSM 49761](/bulletins/10191525.md), 2021-05-03, Service bulletin: ENGINE AND ENGINE COOLING. Some 2011\-2021 Mustang and F\-150 vehicles equipped with a 5.0L engine may exhibit a 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 150F \(65Å’C\) or higher and engine speed is at idle up to approximately 1700 RPMs. 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 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.
- [16\-0074](/bulletins/10183775.md), 2020-12-07, Service bulletin: ENGINE AND ENGINE COOLING. Some 2011\-2014 Mustang vehicles equipped with a 3.7L engine may exhibit coolant pump leakage due to air entering the system.
- [SSM 49318](/bulletins/10183567.md), 2020-12-04, Service bulletin: EQUIPMENT. For 2011\-2020 F\-150/Mustang vehicles equipped with a 5.0L engine when installing a replacement secondary timing chain tensioner \(6K254\) or secondary timing chain guide \(6K297\), it is necessary to replace both components as a pair, using the latest level parts. Make sure to use secondary timing chain tensioner part number ML3Z\-6K254\-A and secondary timing chain guide part number ML3Z\-6K297\-A.
- [TSB 20\-2233](/bulletins/10177863.md), 2020-08-06, Service bulletin: STRUCTURE. This article supersedes TSB 19\-2026 to update the vehicle model years affected. Some 2000 and newer Ford/Lincoln/Mercury vehicles equipped with aluminum body panels may exhibit corrosion concerns appearing as bubbled and/or peeling paint with or without accompanying white dust. Panel replacement is recommended.
- [SSM 48130](/bulletins/10164508.md), 2019-09-06, Service bulletin: VISIBILITY:GLASS, SIDE/REAR; VISIBILITY. Some 2010\-2020 vehicles may exhibit distorted glass with a subtle orange peel pattern or streaking etched into the surface. This is caused by hydrofluoric acid which is used in some car wash solutions as a cleaning agent. Hydrofluoric acid can attack the glass and cause visual distortion and/or discoloration on the outer surface which cannot be removed by further cleaning. If this type of distortion is found, inspect the area of the glass that is covered by the cowl and/or molding. The portion of glass that is covered by the cowl or molding will not be affected by the acid. Hydrofluoric acid damage is not a defect in material or workmanship and is not a warrantable condition.
- [SSM 48070](/bulletins/10163573.md), 2019-08-07, Service bulletin: ELECTRICAL SYSTEM; EQUIPMENT:APPLIANCE:AIR CONDITIONER. Some 2009\-2017 Expedition/Navigator, 2009\-2014 F\-150/Mustang, 2008\-2009 Sable, 2008\-2019 Taurus/Flex/MKT, 2013\-2019 Police Interceptor Sedan/Utility, and 2011\-2019 Explorer vehicles may exhibit inoperative or intermittent HVAC blower motor function at various fan speed settings. This may be due to a poor electrical connection at the blower motor speed control. If the blower motor speed control is determined to be the causal part, replacement of the electrical connector pigtail harness \(14S411\) to the blower motor speed control is also recommended to avoid repeat repairs. Use pigtail harness service part numbers 3U2Z\-14S411\-ZEA or CU2Z\-14S411\-FA, as both parts are interchangeable. Refer to Wiring Diagram, Cell 5 for recommended splicing procedures.
- [SSM 47976](/bulletins/10160931.md), 2019-06-07, Service bulletin: POWER TRAIN. On vehicles equipped with an automatic transmission it is imperative that the converter pilot hub be greased with Motorcraft Multi\-Purpose Grease Spray XL\-5\-A even if grease was not applied from the factory. Also verify that the engine/transmission alignment dowel pins are present as well as the engine crankshaft dowel pin, if equipped, when installing the transmission. Failure to adequately lubricate the converter hub greatly increases the likelihood of the flexplate cracking in the future. Missing dowels may cause a misalignment issue also resulting in a premature failure. Refer to Workshop Manual \(WSM\), Section 307\-01.
- [SSM 47830](/bulletins/10156888.md), 2019-04-08, Service bulletin: ENGINE. Some 5.0L 4V engines may exhibit a tick/tap/rattle or knock immediately after secondary timing chain tensioner installation. In some cases the secondary timing chain tensioners are not fully released during installation.To confirm, remove both valve covers and inspect the secondary timing chains and tensioners. If the chain is loose fitting and the tensioner does not appear to be extended, using your hand depress the chain/guide and tensioner several times or until the tensioner releases taking up the slack in the chain. If the chain does not have slack, follow Workshop Manual Section 303\-00 to diagnose.
