Service bulletin SSM 52517

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.

NHTSA's summary

Some 2024 F-150 vehicles equipped with a gasoline, hybrid or flex fuel engine (non-Lightning) may exhibit inoperative A/C, lack of air flow and/or evidence of the evaporator freezing. This may be due to the software level of the heating, ventilation and air conditioning (HVAC) module. Reprogram the HVAC module using the latest software level of the FDRS diagnostic scan tool. Follow all on-screen instructions carefully to complete all coordinated module software updates. For claiming, use causal part RECAL and use applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
