Service bulletin B640224
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 coolant changeover valve may develop a coolant leak when the outside temperatures go below 19°F (-7°C). The vehicles operating systems would also need to be at that same low temperature (example: being parked outside, overnight in low temperatures).
