# Service bulletin SSM 52307

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.

- Type: Service bulletin
- NHTSA id: 10250852
- Published by NHTSA: 2024\-03\-05
- Manufacturer's number: SSM 52307
- Manufacturer's date: 2024\-02\-29
- NHTSA component: ELECTRICAL SYSTEM

## NHTSA's summary

Some 2020\-2023 Ford and Lincoln SYNC3 equipped vehicles may experience an inaccurate notification in the FordPass®/LincolnWay® app indicating Vehicle Has Entered Deep Sleep Mode. Vehicle Has Entered Deep Sleep Mode message is expected if the vehicle has not been started for 14 consecutive days, battery voltage is at/below 9.5 volts or the body control module \(BCM\) 12 volt battery state of charge \(SoC\) drops below 50%. If the vehicle is going into deep sleep due to one of these conditions, follow normal Workshop Manual \(WSM\) Section 414\-01 procedure to correct the concern. If the vehicle is going into deep sleep outside these conditions, this may be due to the telematics control unit \(TCU\) software. To correct this condition, follow the Service Procedure to update the TCU to the latest software. For claiming, use causal part 14G229 and applicable labor operations in Section 10 of the Service Labor Time Standards \(SLTS\) Manual.

- [TSB 26\-2375 v2](/bulletins/11038441.md), 2026-10-13, Service bulletin: UNKNOWN OR OTHER; ELECTRICAL SYSTEM; POWER TRAIN. NOTE: This bulletin has been updated, refer to the change log at the bottom for details. Issue: Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: • Poor shift quality • Illuminated powertrain malfunction \(wrench\) indicator with DTCs P2704 and P0771 stored in the PCM / TCM . This may be due to a calibration in the TCM and/or wear between the input shaft and the E clutch hub causing theinput shaft O\-rings to become damaged resulting in an open E clutch circuit. Action: For vehicles that meet all of the criteria in the Issue and Model statements, follow the Service Procedure toreprogram the PCM / TCM and/or replace the E clutch hub and input shaft O\-rings
- [SSM 55221](/bulletins/11038438.md), 2026-10-12, Service bulletin: UNKNOWN OR OTHER; POWER TRAIN; ELECTRICAL SYSTEM. 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.
- [TSB 26\-2325](/bulletins/11037978.md), 2026-10-05, Service bulletin: EXTERIOR LIGHTING; ELECTRICAL SYSTEM; UNKNOWN OR OTHER. Some of the vehicles listed in the Model statement above may exhibit a front courtesy lamp that is inoperative. This may be due to a concern with the front courtesy lamp light module.
- [SSM 55215](/bulletins/11037783.md), 2026-10-02, Service bulletin: ELECTRICAL SYSTEM; SERVICE BRAKES; UNKNOWN OR OTHER. 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.

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
