## 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.
- [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.
- [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.
- [TSB 26\-2428](/bulletins/11037776.md), 2026-10-02, Service bulletin: ELECTRICAL SYSTEM; FUEL/PROPULSION SYSTEM; UNKNOWN OR OTHER; POWER TRAIN. This bulletin supersedes 25\-2326. Reason for update: update the service procedure to include the fuel tank isolation valve replacement, update the causal part number, and increase the labor time allowance to include the fuel tank isolation valve replacement. Some of the vehicles listed in the Model statement above may exhibit an illuminated malfunction indicator lamp \(MIL\) with diagnostic trouble code \(DTC\) P2450 stored in the powertrain control module \(PCM\). This may be due to the software in the PCM and/or the fuel tank isolation valve.

Reason for update: update the service procedure to include the fuel tank isolation valve replacement, update the causal part number, and increase the labor time allowance to include the fuel tank isolation valve replacement. Some of the vehicles listed in the Model statement above may exhibit an illuminated malfunction indicator lamp \(MIL\) with diagnostic trouble code \(DTC\) P2450 stored in the powertrain control module \(PCM\). This may be due to the software in the PCM and/or the fuel tank isolation valve.

- [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

Reason for update: update the labor operation numbers to add MT to operations C, F, G, H, J, K, L and M, and correct the part number LIMZ\-4A015\-B to L1MZ\-4A015\-B. Some of the vehicles listed in the Model statement above may exhibit at least one of the following conditions: Harsh engagement Delayed engagement Harsh shift Delayed shift Illuminated malfunction indicator lamp \(MIL\) with diagnostic trouble codes \(DTC\)s P0751, P0752, P0756, P0757, P0761, P0762, P0766, P0767, P0771, P0772, P2700, P2701, P2702, P2703, P2704, P2705, P2707, P2708, P0729, P0731, P0732, P0733, P0734, P0735, P0736, P076F, P07D9, P07F6 and/or P07F7 stored in the powertrain control module \(PCM\) or transmission control module \(TCM\). This may be due to axial movement of the CDF clutch cylinder sleeve causing hydraulic circuit leaks. NOTE: If internal transmission service is required to address a concern detected with the CDF clutch cylinder following this article, technicians should carefully inspect and replace other transmission components and flush transmission fluid cooler only as ne
