Service bulletin RFI20201207_599-

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

This SKU is a Climate Control Module. The customer communication requested return of unsold inventory to inspect for a software issue. If the software issue exists it can cause a fan in the climate control system to stay on even when the ignition is turned off. The fan staying on even though the ignition is off can drain the battery, making the vehicle unable to start.
