Service bulletin SSPC7a

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.

07-006-20-37582021-01-05. Service bulletin. Some customers may complain that after accelerating in hot weather, the A/C blows warm air for a longer time than other models. This is caused by improper control software of the PCM not allowing the A/C compressor to resume properly after acceleration. To eliminate this concern, the control software of the PCM has been modified.
SA-065-202020-10-05. Service bulletin. Some customer's may complain that the HVAC system only blows warm to cool air (not cold) after starting the vehicle and not moving right away. This may be caused by a closed Active Air Shutter (AAS). Under specific circumstances, the AAS has a “learning issue” where AAS is kept closed after startup even if the PCM requests it to be open. The shutters will open and work correctly as soon as the vehicle speed exceeds 6.25 MPH (10 KPH). NO DTC will be set when this happens.
