Official summary
This article supersedes TSB 25-2058 to update: service procedure enhancements, and increase labor operation allowances. Some of the vehicles listed in the Model statement above may exhibit a 12-volt battery drain. This may be due to the software level of various modules such as the gateway module (GWM), accessory protocol interface module (APIM) and driver front seat module (DSM).
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
