"The hybrid battery tray may not drain water sufficiently," said NHTSA in its recall summary. "If water collects in the hybrid battery tray, it may cause an electrical short in the high-voltage battery. An electrical short in the high-voltage battery increases the risk of a fire."
There are no reports of accidents, injuries or fires in the U.S., VW spokesman Mark Gillies told Edmunds.
The affected vehicles were built from March 20, 2010 to April 11, 2015.
Volkswagen dealers will install a fitted drain valve to allow water to drain properly. The recall is expected to begin in late February. Owners can contact Volkswagen customer service at 1-800-893-5298.
Edmunds says: Owners of these vehicles should be in touch with their dealer soon to make a service appointment.
