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.

SSM 52476	2024-05-03. Service bulletin. 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.
SSM 52334	2024-03-20. Service bulletin. 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.

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.

SSM 49318	2020-12-04. Service bulletin. 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.

SSM 48070	2019-08-07. Service bulletin. 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 47850	2019-05-07. Service bulletin. 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.
