Manufacturer: Toyota Motor North America, Inc.

Report Receipt Date: NOV 14, 2012

NHTSA CAMPAIGN ID Number: 12V536000

NHTSA Action Number: N/A

Component: ENGINE AND ENGINE COOLING

Potential Number of Units Affected: 350,662

Summary:
Toyota is recalling certain model year 2004-2009 Prius vehicles manufactured August 6, 2003, through March 30, 2009 and FCHV-adv vehicles manufactured December 12, 2008, through September 13, 2011. During manufacturing, a scratch may have occurred inside of the electrically driven water pump at the coil wire. The coil wire may corrode at the scratched portion.

Consequence:
The corroded coil wire may break and the water pump could stop. The corroded coil wire could cause a short circuit between coil wires and a possible open fuse, creating a stall-like condition of the hybrid system while the vehicle is being driven. This may increase the risk of a vehicle crash.

Remedy:
Toyota will notify its owners, and dealers will replace the electric water pump, free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact their Toyota dealer or the Toyota Customer Experience Center at 1-800-331-4331.
