# Service bulletins for the 2014 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.

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

Follow the instructions on the screen to obtain the master code for the accessory keypad.
- [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.
- [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.
- [SSM 50804](/bulletins/10212957.md), 2022-06-01, Service bulletin: ELECTRICAL SYSTEM. Some 2013\-2023 Ford or Lincoln vehicles with modems activated through FordPass or LincolnWay may experience 12 volt battery drain symptoms when the customer uses non\-Ford/Lincoln phone applications as an alternate channel to access vehicle commands such as door lock/unlock, remote start, vehicle location, etc. The battery drain may be caused by excessive calls for data through the vehicle network keeping it in an activated state. Recommend that the customer uninstall the app to ensure this is not contributing to battery symptoms experienced. Advise the customer that unaffiliated third\-party app developers do not work directly with Ford to adhere to security, vehicle communication, and privacy requirements.
- [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.

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 47850](/bulletins/10159489.md), 2019-05-07, Service bulletin: ELECTRICAL SYSTEM; EQUIPMENT:APPLIANCE:AIR CONDITIONER. Some 2013\-2019 vehicles equipped with a EVDC air conditioning \(A/C\) compressor may exhibit poor A/C performance/improper climate function and/or a diagnostic trouble code \(DTC\) P06A0 in the powertrain control module \(PCM\). To support the proper diagnosis of this compressor, the EVDC control valve tester has been developed and is available from Rotunda \(339\-EVDC100\). A tester has been provided to each U.S. dealership free of charge with shipments completed 19\-Apr\-2019 \(reference EFC07013 on FMCDealer.com\). This tester will help reduce the potential for misdiagnosis and unnecessary compressor replacement. Make sure that this tester is used for warranty repairs and document the test results in the Technician Comments field. Refer to the Rotunda catalog for a video and user manual which provide detailed operating instructions.
- [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. The Workshop Manual section 303\-01C has been updated to reflect the installation releasing process for the secondary timing chain tensioner.
