Bulletins, newest first
20U122020-06-05. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:DIESEL. Some of the affected vehicles may have a valve seat that is below the required retention force or not fully seated into one of the cylinder heads. A valve seat that is out of position may cause the illumination of the check engine light and may lead eventually to engine damage and potentially resulting in engine failure.
TSB 20-21712020-06-05. Service bulletin. STRUCTURE:FRAME AND MEMBERS:UNDERBODY SHIELDS; SEATS. Some 2013-2018 C-Max, 2013-2020 Escape/Fusion/MKZ, 2015-2018 Focus,2015-2019 MKC, 2015-2020 Edge/F150/Mustang, 2016-2018 MKX, 2016-2019 Explorer, 2017-2020 F-Super Duty, 2018-2020 EcoSport/Expedition, 2019-2020 Ranger/Nautilus vehicles may experience seat pan looseness, lateral movement, or a clunk/thump noise on turns. This may be due to the seat pan track. To correct the condition, follow the Service Procedure steps to install a reinforcement.
TSB 20-21702020-06-05. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Some 2018-2020 F-150/Expedition/Navigator/F-Super Duty vehicles built on 31-Aug-2018 and through 02-Feb-2020 may exhibit a water leak on the right front floor during and/or after the air conditioning (A/C) is used. This may be due to condensation from the evaporator drain tube entering the vehicle through the drain tube seal. To correct the condition, follow the Service Procedure steps to install an elbow on the evaporator drain tube to direct the condensation away from the seal.
SSM 488592020-06-04. Service bulletin. TIRES:PRESSURE MONITORING AND REGULATING SYSTEMS; ELECTRICAL SYSTEM. Some 2020 F-Super Duty vehicles built on or before 24-Feb-2020 may not have the instrument panel cluster (IPC) configured for operation with the Factory Invoiced Accessory (FIA) or as a Genuine Ford Accessory trailer tire pressure monitoring system (TPMS). The customer may indicate that they cannot monitor the trailer TPMS through the IPC when a configured trailer is connected. If the 'Trailer Tire Pressure' selection is not available in the IPC, the IPC will need to be reconfigured to make the Trailer Tire Pressure selection available. Using the latest version of the FDRS scan tool, reconfigure the IPC. For claiming use causal part 10849 and refer to Section 10 of the Service Labor Time Standards (SLTS) Manual.
SSM 488582020-06-04. Service bulletin. ELECTRICAL SYSTEM. Some 2012-2020 Ford and Lincoln vehicles equipped with a TCU may exhibit an inoperative remote start with a 'Vehicle Failed To Start' message when using MyFord Mobile/Ford Pass/Lincoln Way mobile applications. The cellular cloud systems will only allow two remote start requests from the MyFord Mobile/Ford Pass/Lincoln Way apps without a vehicle drive event occurring. If a third remote start request is received, a Vehicle Failed To Start message will be displayed quickly in the mobile app. Once the vehicle is driven, the remote start counter is reset and will allow remote start commands to be sent from the mobile app. If the remote start system is not functioning using the key fob, refer to Workshop Manual (WSM) Section 303-06 for further diagnosis.
SSM 488202020-06-04. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION; ENGINE AND ENGINE COOLING. Some 2020 F-350, F-450, and F-550 F-Super Duty chassis cab vehicles equipped with a 6.7L diesel engine and 10R140 automatic transmission may exhibit a delay/bump feel when pulling away from a stop. This may be due to the neutral idle feature that automatically reduces the load on the engine when the vehicle stops, and the gear selector is in DRIVE to reduce fuel consumption and emissions. The transmission automatically resumes operation when the brake is released. The neutral idle feature activates when the transmission is sufficiently warmed, and the vehicle is on level grade. Do not attempt any repairs for this condition. Refer to Owners Manual Transmission Section for more information.
20B152020-05-05. Service bulletin. ENGINE AND ENGINE COOLING. In some of the affected vehicles , a piston oil cooler bracket may have been damaged during engine assembly. A damaged piston oil cooler bracket may allow the piston oil cooler to detach. This can lead to low engine oil pressure and may result in intermittent engine noises and/or illumination of the check engine light due to diagnostic trouble code(s).
SSM 487792020-05-04. Service bulletin. ELECTRICAL SYSTEM. 2020 F-Super Duty vehicles equipped from the factory with an exterior backup alarm will also experience an interior chime when the vehicle is placed into the reverse position. This chime may come through the vehicles audio system or through the instrument cluster. This interior chime is characteristic to vehicles that are equipped with a factory exterior backup alarm and no repairs are recommended.
SSM 487772020-05-04. Service bulletin. EQUIPMENT:ELECTRICAL; EXTERIOR LIGHTING. Some 2020 F-Super Duty vehicles may exhibit a condition where the turn signals flash fast after removal of the factory pick up box and tail lamps for flatbed installation. To prevent the turn signals from flashing fast, the BCM will need to be configured using the FDRS scan tool. Start a vehicle session in FDRS using the vehicles VIN and go to the toolbox tab. The BCM will have an application labeled Turn Signal Lamp Configuration. Download and run this application to configure the turn signals.
SSM 487612020-05-04. Service bulletin. POWER TRAIN. Some 2020 F-Super Duty vehicles equipped with a 6.2L or 7.3L gas engine and a 10R140 transmission may exhibit an intermittent buzz noise coming from the transmission while the vehicle is in transport mode. This condition is most noticeable with the vehicle in PARK or NEUTRAL and at elevated idle speeds of 850 to 1250 revolutions per minute (RPM). This condition is a normal characteristic while in transportation mode and will be eliminated once the vehicle is placed into normal mode prior to customer delivery. Do not attempt to repair.
SSM 487572020-05-04. Service bulletin. ELECTRICAL SYSTEM. Some customers may experience a notification in the FordPass and/or LincolnWay apps that indicates their vehicle has entered "deep sleep mode". This mode is enabled due to the vehicle not being started for 14 consecutive days or battery voltage is at/or below 9.5 volts. Some 2020 models will also set a warning if the telematic control unit (TCU) has received an automatic over the air update. The purpose of deep sleep mode is to conserve battery voltage. When deep sleep mode is enabled, the TCU is powered down and all communication with the FordPass and/or LincolnWay apps are disabled. To wake the vehicle from deep sleep mode, manually start the vehicle. More deep sleep mode information can be found in the FordPass or LincolnWay apps under: More > Guides > click in search entry box > type "deep sleep" and click on "Ask".
SSM 487442020-05-04. Service bulletin. EXTERIOR LIGHTING; ELECTRICAL SYSTEM. Some 2020 F-Super Duty vehicles may exhibit a condition where the turn signals flash faster after removal of the factory pick up box and tail lamps for flatbed installation. Engineering is working to implement a solution for this condition. Advise the customer that a solution through FDRS is expected to be available 27-Apr-2020. Dealers are asked to follow-up with their customers to schedule a service appointment once the solution becomes available. Monitor OASIS for updates.
SSM 487172020-05-04. Service bulletin. EQUIPMENT:ELECTRICAL. Some 2020 F-Super Duty vehicles equipped with the Blind Spot Information System (BLIS) and Cross Traffic Alert (CTA) may require the removal of the factory equipped tail lamps to accommodate the use of aftermarket equipment. Once the tail lamps are removed, this may result in BLIS and CTA warning indicators illuminated in the instrument panel cluster (IPC). To clear these warning indicators, the BLIS and CTA systems will need to be disabled using the FDRS scan tool. Start a vehicle session in FDRS using the vehicles VIN and go to the toolbox tab. The BCM will have an application labeled Disable/Enable Blind Spot Information System. Download and run this application to enable or disable the BLIS And CTA systems.
SSM 486192020-04-02. Service bulletin. UNKNOWN OR OTHER; ELECTRICAL SYSTEM.

This concern would most often occur when a customer loses keys and the dealership is attempting to program new keys to the vehicle. The Workshop Manual (WSM), Section 419-01A Perimeter Anti-Theft Alarm - System Operation and Component Description has been updated to inform of the Controller Area Network (CAN) Protection Strategy. Follow the procedure outlined to prevent replacement of the Body Control Module (BCM) on CAN Protection Strategy equipped vehicles when original keys are lost and perimeter alarm is active. Refer to the WSM for further detail on the CAN Protection Strategy. Lost keys and replacement of BCM for lost keys is non-warrantable.
