Service bulletin G-177384
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
13324 - Customer Satisfaction. Certain vehicles may have an incorrect calibration in the instrument cluster. This will cause the speedometer needle to read 8 mph lower than the actual vehicle speed. A speedometer needle reading below zero during vehicle idle is evidence of this condition. Dealers are to inspect and, if necessary, replace the instrument cluster.
