Service bulletin 07-004-24b
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 vehicles may exhibit that, after using the cabin preconditioning, when starting the engine, the CHECK ENGINE light illuminates with DTC P0531:00 (Refrigerant pressure sensor No.1 system: Function malfunction) stored in memory. NOTE: If the cabin preconditioning was not used, this TSB is not applicable. (DTC P0531:00 concern without using the cabin preconditioning is under investigation.) This is caused by improper control logic of the PCM. To eliminate this concern, the control logic of the PCM has been modified.

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