- [SSM 55211](/bulletins/11038163.md), 2026-10-06, Over\-the\-air update: ENGINE; FUEL/PROPULSION SYSTEM; UNKNOWN OR OTHER. 2023\-2026 Escape and 2025\-2026 Bronco Sport vehicles equipped with a 1.5L EcoBoost engine may require removal of the turbocharger wastegate control actuator linkage for various reasons. The Workshop Manual \(WSM\), Section 303\-04 Fuel Charging and Controls \- Turbocharger \- 1.5L EcoBoost \> Removal and Installation \> Wastegate Control Actuator Linkage service procedure has been added. In addition, the wastegate control actuator linkage rod with retaining clips \(6K682\) and actuator linkage rubber boot seal \(9E416\) have been released as lower\-level components to complete the repair without replacing the entire turbocharger wastegate control actuator assembly.
- [SSM 55142](/bulletins/11037059.md), 2026-09-04, Service bulletin: POWER TRAIN; ENGINE; ELECTRICAL SYSTEM. Some 2023\-2025 Escape vehicles built on or before 16\-Sep\-2024 equipped with 1.5L EcoBoost engine may exhibit an "Engine Coolant Over\-Temperature" warning message displayed in the IPC and an illuminated MIL with DTCs P1285 and/or P1299 stored in the powertrain control module \(PCM\) during hard acceleration or under high load conditions. This may be due to machining chips trapped in the cylinder head causing a potential blockage in the coolant passage near the cylinder head temperature 2 \(CHT2\) port. To diagnose this condition, start the vehicle and idle for 15 minutes. Perform a road test at a temperature above \-20°C \(\-4°F\) and apply wide\-open throttle \(WOT\) hard accelerations in rapid succession. If the concern cannot be replicated, drain and refill the coolant system. If the concern can be replicated, drain the coolant system. Perform the Engine Cooling System Flushing procedure in Workshop Manual \(WSM\) \> 303\-03A Engine Cooling \- 1.5L EcoBoost \> General Procedures. Do not use the VC1 flush additive. Reassemble the engine. Fill and bleed the coolant system and re\-evaluate the concern. If the concern pers

Customer Satisfaction Program 25M03 Certain 2020\-2025 Model Year Escape, 2021\-2025 Model Year Corsair and 2022\- 2025 Model Year Maverick Vehicles equipped with a 2.5L Hybrid or Plug\-In Hybrid engine \- Exhaust Gas Recirculation \(EGR\) Differential Pressure Sensor Replacement, if Required After Dealer Evaluation
- [25B33](/bulletins/11034207.md), 2026-07-01, Other: ENGINE. Certain 2023\-2025 Model Year Escape and Corsair, 2024\-2025 Model Year Nautilus, 2025\-2026 Model Year Bronco Sport and 2025 Model Year Maverick Vehicles Equipped with an Engine Block Heater System Block Heater Replacement
- [SSM 54738](/bulletins/11031302.md), 2026-04-14, Service bulletin: ENGINE; POWER TRAIN. Some 2023\-2025 Escape 1.5L/F\-Super Duty/Transit vehicles may exhibit a lack of cooling from the heating, ventilation, and air conditioning \(HVAC\) system, which may be accompanied by abnormal rattling, grinding and/or squealing noises from the engine compartment. This may be due to damage to the air conditioning \(A/C\) compressor internal components and/or clutch assembly. Confirm ambient air temperature is above approximately 0°C \(32.0°F\). On the HVAC controls, set the temperature to full cold \(not MAX A/C\), select PANEL, set the fan speed to the highest setting and select the A/C button \(indicator on\). If the A/C compressor clutch engages and the A/C compressor is noisy, and/or the belt is slipping on the A/C compressor pulley or the A/C compressor is seized, install a new A/C compressor as indicated in Section 412\-00 of the Workshop Manual \(WSM\). For claiming, use causal part 19703 and labor operation MT19700SSM up to 0.3 hours to check for a damaged compressor. If the compressor requires replacement, claim labor operations 19700A and 19700A4. Also claim available Service Labor Time Standards \(SLTS\) op
- [SSM 54631](/bulletins/11029931.md), 2026-03-11, Service bulletin: ENGINE. Some 2020\-2026 Escape and 2022\-2026 Maverick 2.5L Duratec hybrid vehicles may require various repairs on the exhaust system. This may require removal of the exhaust heat exchanger. WSM, Section 309\-00 Exhaust System \> 2.5L Duratec hybrid \> Removal and Installation \> Exhaust Heat Exchanger has been revised to eliminate the need to remove the muffler assembly. The procedure steps and labor times have been updated to reflect this adjustment.
- [SSM 54386](/bulletins/11025808.md), 2025-12-01, Service bulletin: UNKNOWN OR OTHER; ENGINE. For 2021\-2025 Corsair vehicles, if diagnostics lead to the heating ventilation air conditioning \(HVAC\) air registers as the causal part, a new lower level part is available. It is no longer necessary to replace the air registers if only the HVAC air register arm or linkage are damaged.\<br /\> \<br /\> Drivers side \(LJ7Z\-78045K00\-A\)\<br /\> Left center \(LJ7Z\-78045K00\-B\)\<br /\> Right center \(LJ7Z\-78045K00\-C\)\<br /\> Passenger side \(LJ7Z\-78045K00\-D\)

- [SSM 54248](/bulletins/11023564.md), 2025-10-02, Service bulletin: POWER TRAIN; UNKNOWN OR OTHER; ENGINE; ELECTRICAL SYSTEM. Some 2023\-2026 Corsair vehicles may exhibit a concern when changing the fan speed, the fan speed display icon \(OFF/AUTO/fan speed number\) changes to a different language character or symbol. This may be due to the accessory protocol interface module \(APIM\) software. Replacement or reprogramming of the APIM will not resolve this condition. Inform customers that engineering is currently working on a solution for this condition and will be released via software updates delivered over\-the\-air \(OTA\) expected Q4 2025. Software will update automatically if vehicle connectivity is enabled in the vehicles settings. Schedule a service visit for customers who have disabled vehicle connectivity or who report that they did not receive the update by October 2025. Monitor Professional Technician System \(PTS\) for additional information.
