Service bulletin DOR23831-599967

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 water pump has incorrect software installed. The concern is the software is not intended for specific applications and in rare cases where the vehicle cooling system is overheating, the water pump may be damaged by too much current and damage its wiring harness.
