Service bulletin 652012

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

RAD2plus: Radio Causes Battery Drain. The vehicle's battery state of charge is very low after the vehicle was parked for a longer period of time (e.g., overnight). The RAD2+ radio doesn't allow the vehicle to enter full sleep mode, and causes a current draw from the battery with ignition off.
