Service bulletin A911634 2043660-

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

The customer has various complaints about the RSE system and would like to update the software of the RSE tablets. The vehicle cannot be started after it has been off for several days, and there are no indications in the battery history log of battery drain originating from a control unit on the CAN bus. The latest update (available as of March 2016) implements a fix that can prevent one of the RSE units from staying awake while the ignition is off, which can potentially draw the vehicle battery down.
