Service bulletin 24B26

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.

SSM 552212026-10-12. 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.
TSB 26-24282026-10-02. Service bulletin. 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.

SSM 551422026-09-04. Service bulletin. 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
TSB 26-23282026-07-20. Service bulletin. 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 549392026-06-22. Service bulletin. 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
TSB 26-22102026-06-05. Service bulletin. Some of the vehicles listed in the Model statement above may exhibit all of the following conditions: * Engine misfire condition * Illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) P0301, P0302, P0303, and/or P0304 stored in the powertrain control module (PCM)
SSM 548252026-05-19. Service bulletin. Some 2023-2026 Escape vehicles equipped with an 8F35 transmission may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTC) P0767, P0766 and/or P2703 stored in the powertrain control module (PCM) and harsh/no reverse engagement. This may be due to the selectable one-way clutch (SOWC). To correct the condition, remove the transmission. Refer to Workshop Manual (WSM) > Section 307-01. Disassemble the transmission only far enough to access the SOWC. Refer to WSM, Section 307-01 > Overhaul and perform Steps 34-66. Remove the SOWC assembly, disassemble the A-clutch and discard the SOWC. Refer to WSM, Section 307-01 > Overhaul and perform Steps 164-170. Assemble the new SOWC with the A-clutch components. Refer to WSM, Section 307-01 > Overhaul and perform Steps 173-179. The A-clutch seals can be reused unless damaged. Install the new SOWC and reverse the procedure to reassemble the transmission. Overhaul the main control valve body. Refer to WSM, Section 307-01 > Overhaul > Main Control Valve Body. Replace the torque converter seal. Refer to WSM, Section 307-01
