Service bulletin 122-K8T6V-10

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

Subject: Instrument cluster Information: Due to a faulty Timer function for the internal clock in the instrument cluster, there is a possibility that the control unit system will be activated cyclically by the instrument cluster after stopping the vehicle. As a result, the control unit system will not be switched to energy-saving mode, resulting in increased closed-circuit current consumption. This can deplete the vehicle battery if the vehicle is idle for a long time.
