Service bulletin SSM 54140
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.

NHTSA's summary
Some 2021-2024 F-150 vehicles equipped with a B&O audio system (minor feature code IDBBQ), and various 2021-2024 Ford and Lincoln vehicles equipped with a B&O audio system may exhibit a pop noise and/or static in the speakers at start up that cannot be turned down or off using the audio system controls. To confirm a vehicle is built with a certain minor feature code, review the build information by double-clicking the vehicle identification number (VIN) in the upper left corner on Professional Technician System (PTS). This may be due to software in the digital signal processing (DSP) module. To correct this condition, reprogram the DSP module to the latest software level using the Ford Diagnosis and Repair System (FDRS) scan tool. For claiming, use causal part 18B849 and labor operations 12651D and 12651D4.

A recall listed here may apply to some of the same vehicles. Only the manufacturer can say whether it applies to one vehicle.
| SSM 55221 | 2026-10-12. Service bulletin. For 20222026 vehicles equipped with a 8F35 transmission, a revision to the Road Testing Vehicle procedure has been made in the WSM, Section 307-01 > Diagnosis and Testing. This updated procedure improves the diagnosis of customer reported transmission concerns and aids in locating the proper root cause. During diagnosis and testing, details regarding whether the condition is more prevalent when the vehicle is hot or cold, throttle percentage at the time of occurrence, vehicle speed, the specific shift involved, and whether the issue occurs during transmission engagements (N>R, N>D, R>D, and/or D>R) should be noted in the warranty claim. Engineering requests including these detailed operating conditions that will significantly assist with root cause analysis. Diagnosis, testing, and repair should use established labor times outside this article. |

| SSM 55215 | 2026-10-02. Service bulletin. Some 2022-2024 Maverick hybrid vehicles may exhibit various electrical symptoms and/or a no crank/no start condition related to an intermittent 12V battery drain that has discharged the 12V battery. This may be due to the software in the anti-lock brake system (ABS) module. To correct this condition, download and run the "ABS - Anti-lock Brake System (ABS) Module Software Update" and "ACCM - Air Conditioning Control Module (ACCM) Software Update" applications using the latest software level of the Ford Diagnosis and Repair System (FDRS) scan tool. For claiming use causal part 2005 and labor operations 10654C and 12651D along with MT2005SSM up to 0.7 hours for the ABS, ACCM, PCM, and SOBDMC as needed. |

| SSM 55208 | 2026-09-30. Service bulletin. Some 2024-2026 F-150, 2025 Explorer/Aviator, 2025-2026 Expedition/Navigator, or 2026 F-Super Duty vehicles may exhibit diagnostic trouble code (DTC) U211B:43:48 stored in the body control module (BCM) when performing a Self-Test. This DTC sets due to an internal BCM timing issue during the self-test process. This specific code has no customer impact and does not cause any drivability concerns or warning messages. Clearing DTC U211B:43:48, reprogramming the BCM, or replacing the BCM is unlikely to prevent this DTC from setting. This DTC does not trigger a condition covered under warranty. Note: This guidance only applies to U211B with the specific failure byte 43 in status 48. Any other trusted real-time operation network (TRON) DTCs or different failure bytes associated with U211B are still applicable and technicians must follow Workshop Manual (WSM) normal diagnostics for those DTCs. |
| SSM 55194 | 2026-09-30. Service bulletin. Some 2021-2024 Mustang Mach-E, 2025-2026 Navigator and 2024 F-150 vehicles may exhibit inoperative welcome/approach detection lights. This may be due to the body control module (BCM) software. To correct the condition, download and run the "BCM - Programmable Module Installation (PMI)" application using the latest software level of the Ford Diagnosis and Repair System (FDRS) scan tool. If the condition persists after PMI, refer to Workshop Manual (WSM), Section 417-01 for normal diagnostics and repair as necessary outside of this article. For claiming, use causal part 15604 and labor operations 12651D and BCM. |

| SSM 55157 | 2026-09-15. Service bulletin. Some 2022-2024 Maverick Hybrid vehicles may exhibit an intermittent vibration and/or crunching noise after a cold start while the engine is running with the vehicle stationary in drive with no throttle input and brakes applied. An intermittent engine rocking or rolling motion in one direction may also be observed while the concern is present with the hood open.<br /><br /> The noise may be present with no drivability concerns, relevant diagnostic trouble codes (DTC) stored, warning indicators illuminated and/or warning messages displayed. The noise may reduce or be eliminated after several minutes of driving when the powertrain warms up.<br /><br /> This condition does not affect vehicle durability and no additional diagnosis or service is required for this condition at this time. Inform customers that they can continue to drive the vehicle and engineering is currently working on a solution for this condition that is expected in Q4 of 2026. Replacement of the engine or transmission will not resolve this condition. Monitor Professional Technician System (PTS) for additional information and schedule s |
| TSB 26-2414 | 2026-09-14. Service bulletin. This article supersedes 26-2058 Reason for update: update the TSB title and TSB issue to include new DTCs Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: * Intermittent or permanent no reverse (R) engagement * Illuminated MIL with DTC P0767 or P0765:7E stored in the powertrain control module (PCM) In addition to the required conditions, the vehicle may also exhibit a harsh reverse engagement, P0766, P0765:7F, P0736 and/or P2703 stored in the PCM. This may be due to an internal mechanical concern with the selectable one-way clutch (SOWC). |
