Service bulletin TSB 26-019
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
TSB (Technical Service Bulletin) - The battery isolation manager connections require a repair. The improper connection can result in a parasitic drain on the chassis battery and a nuisance check engine light on the dash. Once the battery isolation manager connections are properly repaired, the chassis battery drain will be eliminated.
