Service bulletin CPI470375
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.

While occasional leaks from the weep hole are not uncommon and completely normal, excessive leaking has been found on some water pumps that failed.
