# Service bulletin SSM 51459

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: 10233742
- Published by NHTSA: 2023\-04\-05
- Manufacturer's number: SSM 51459

## NHTSA's summary

Some 2020\-2022 Escape/Corsair, 2021\-2022 Bronco Sport, and 2022 Maverick vehicles built on or before 23\-Mar\-2022 may exhibit a hard, stiff, and/or difficult to turn condition due to a lack of power steering assist during engine start\-up with U3000 diagnostic trouble codes \(DTCs\) stored in the PSCM. Using the latest version of Ford Diagnosis and Repair System \(FDRS\) tool, select and run the PSCM \- Reset the Power Steering Control Module \(PSCM\) application. After PSCM reset, perform an ignition cycle. Update the PSCM to the latest software level using FDRS tool. If the U3000 DTC returns, continue with diagnostics and repair direction using Workshop Manual \(WSM\), Section 211\-02 \> Power Steering \> Diagnosis and Testing. For claiming, use causal part 3C529 and applicable labor operations in Section 10 of the Service Labor Time Standards \(SLTS\) Manual.

## Other bulletins for the same vehicles and component

- [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\-2328](/bulletins/11035099.md), 2026-07-20, Service bulletin: POWER TRAIN; UNKNOWN OR OTHER. This bulletin supersedes 26\-2194. Reason for update: update the Parts list to correct a part description " Loctite 638", update the claim quantity for the drain/fill plug, update the claim quantity of the wheel hub bolts \(Corsair\) and limited the parts list for Edge/Nautilus to only the rear drive unit fluid. Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: Shudder chatter condition, most noticeable at low speeds turning No relevant diagnostic trouble codes \(DTCs\) present This may be due to internal rear drive unit \(RDU\) fluid contamination.
- [SSM 54980](/bulletins/11034857.md), 2026-07-08, Service bulletin: POWER TRAIN; FUEL/PROPULSION SYSTEM; ENGINE. 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. 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. 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 Q3 of 2026. Replacement of the engine or transmission will not resolve this condition. Monitor Professional Technician System \(PTS\) for additional information and schedule
- [SSM 54939](/bulletins/11034017.md), 2026-06-22, Service bulletin: POWER TRAIN. Some 2020\-2026 Corsair/Escape, 2021\-2026 Bronco Sport, and 2022\-2026 Maverick vehicles equipped with an 8F35 transmission may exhibit a shudder condition, most noticeable at speeds below 60 mph \(100 km/h\), with no relevant diagnostic trouble codes \(DTC\) stored in the powertrain control module \(PCM\). Sometimes, this may be perceived/felt as an engine misfire. This may be due to the torque converter. If Pinpoint Test K: Torque Converter Clutch Operation in Workshop Manual \(WSM\), Section 307\-01 \> Diagnosis and Testing \> Diagnosis by Symptom directs to replace the torque converter, remove and replace the torque converter and torque converter seal. Refer to WSM, Section 307\-01 \> Removal and Installation \> Torque Converter Seal. Remove the main control valve body. Refer to WSM, Section 307\-01 \> Removal and Installation \> Main Control Valve Body. Overhaul and thoroughly clean the main control valve body. Refer to WSM, Section 307\-01 \> Overhaul \> Main Control Valve Body. Reverse the removal procedure to reassemble the transmission. Install the transmission. Refer to WSM, Section 307\-01 \> Installation. For claim
- [SSM 54797](/bulletins/11032566.md), 2026-05-08, Service bulletin: POWER TRAIN. Some 2020\-2026 Corsair/Escape, 2021\-2026 Bronco Sport, and 2022\-2026 Maverick vehicles equipped with an 8F35 transmission may exhibit a shudder condition, most noticeable at speeds below 60 mph \(100 km/h\), with no relevant diagnostic trouble codes \(DTC\) stored in the powertrain control module \(PCM\).

- [TSB 26\-2194](/bulletins/11031619.md), 2026-04-28, Service bulletin: POWER TRAIN. This bulletin supersedes 25\-2627. Reason for update: To add a Step to reprogram the all\-wheel drive \(AWD\) module for Bronco Sport vehicles. Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: Shudder chatter condition, most noticeable at low speeds turning No relevant diagnostic trouble codes \(DTCs\) present This may be due to internal rear drive unit \(RDU\) fluid contamination.
- [SSM 54615](/bulletins/11029540.md), 2026-03-04, Service bulletin: FUEL/PROPULSION SYSTEM; ELECTRICAL SYSTEM; POWER TRAIN. Some 2020\-2026 Escape and 2021\-2026 Corsair vehicles equipped with a 2.5L engine may exhibit a fuel door that won't open with diagnostic trouble code \(DTC\) P04CA stored in the powertrain control module \(PCM\). This may be due to an open circuit on circuit SBB05 and/or a damaged splice S133. Before performing the pinpoint test for P04CA in Workshop Manual \(WSM\), Section 310\-00, inspect circuit SBB05 and splice S133 for damage such as an open circuit. Repair as necessary. Refer to Wiring Diagram, Cell 005. If no damage is found, refer to WSM, Section 310\-00 for normal diagnostics. For claiming use causal 14290 and labor operations 12650D, 12650D45, and 12650D45WR.
