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.

TSB 22-21472022-04-26. Service bulletin. EQUIPMENT; POWER TRAIN:AUTOMATIC TRANSMISSION; ELECTRICAL SYSTEM:SOFTWARE. Some 2020-2021 Escape and 2021 Corsair vehicles equipped with a 2.5L full hybrid electric vehicle (FHEV) or 2.5L plug-in hybrid electric vehicle (PHEV) powertrain may exhibit a no crank/no start condition due to the passive anti-theft system (PATS) immobilizer being enabled. This may be more prevalent after a vehicle service/repair. This may be due to software that renders the inverter system controller (ISC) (also known as secondary on-board diagnostic module C (SOBDMC)) inoperable when a vehicle repair requires a PATS update. To correct the condition, follow the Service Procedure to reprogram various modules starting with the powertrain control module (PCM).
SSM 502122021-10-29. Service bulletin. POWER TRAIN:CLUTCH ASSEMBLY; POWER TRAIN:AUTOMATIC TRANSMISSION:TORQUE CONVERTER; POWER TRAIN. Some 2020-2021 Corsair vehicles built on or before 03-Mar-2021 with the 8F40 transmission may have a torque converter clutch that will not release/unlock at below 5 mph (8 km/h). This may be due to an internal issue with the torque converter clutch (TCC). If this condition is present, install a new torque converter assembly. Refer to Workshop Manual (WSM), Section 307-01. For claiming, use causal part 7902 and applicable labor operations in Section 7 of the Service Labor Time Standards (SLTS) Manual.
