Service bulletin TSB 21-2342
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 55149 | 2026-09-12. Service bulletin. Some 2021-2024 Bronco Sport vehicles equipped with a 1.5L may exhibit a lack of air conditioning (A/C) cooling while at a stop and idling in ambient temperatures of 100°F (38°C) or higher. In addition, there are no diagnostic trouble codes (DTC) present related to A/C system functionality, refrigerant charge levels are to specification and system is free of refrigerant leaks and/or A/C compressor related concerns. Customers may also report that A/C system cooling will be restored once the vehicle starts moving or placed in park/neutral.<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 2026. Replacement or reprogramming of any components will not resolve this condition. Monitor Professional Technician System (PTS) for additional information and schedule service appointments for customers once the repair becomes available.<br /><br /> If the vehicle exhibit |
| TSB 26-2395 | 2026-09-01. Service bulletin. This article supersedes 26-2287. 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 |

| SSM 55069 | 2026-08-11. Service bulletin. Some 2020-2025 Explorer vehicles equipped with a power roof opening panel may exhibit a sunshield with localized bunching or binding/inoperative. This may be due to a broken or missing sunshield fabric retainer/clip. A revised sunshield clip (LJ6Z-5452118-B) is now available to address this condition. It is not necessary to replace the entire sunshield assembly if the clip(s) are broken or missing. Refer to Workshop Manual (WSM), Section 501-17 Roof Opening Panel > General Procedures > Inspection and Replacement of the Roof Opening Panel Shield Clip. |
| TSB 26-2359 | 2026-08-10. Service bulletin. Some of the vehicles listed in the Model statement above may exhibit an incorrectly illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P0420 stored in the powertrain control module (PCM). This may be due to the software in the PCM. |
| SSM55059 | 2026-08-03. Service bulletin. Some 2021-2023 F-150 vehicles equipped with a 3.5L PowerBoost engine, 2020-2026 Explorer vehicles equipped with a 3.3L hybrid engine, and 2020-2023 Lincoln Aviator vehicles equipped with a 3.0L EcoBoost hybrid engine may exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble code (DTC) P0A1E stored in the powertrain control module (PCM). The vehicle may be unable to enter electric-only drive modes as expected during normal drive cycles. This may be due to the belt integrated starter generator (BISG). For vehicles with this condition, follow the necessary Pinpoint Test in Workshop Manual (WSM), Section 303-06 for DTC P0A1E and repair the vehicle as directed. Note that previous replacement of the BISG does not negate the need for subsequent BISG replacements if directed to do so by the appropriate Pinpoint Test diagnostics. Engineering is investigating this BISG quality concern. Monitor PTS for updates regarding this investigation. |
