Recall Details

An update to the software for the vehicle interface control module (VICM) may have disabled proper cell balancing functionality of the electric drive battery. Dealers will reprogram the VICM free of charge to resolve the concern.

Our Quick Take

The electric drive battery condition may deteriorate due to a software update to the vehicle interface control module (VICM) that may have disabled battery cell balancing functionality.  This would cause a low voltage condition, and a loss of vehicle propulsion that increases risk of a crash.
