Chevrolet Volt: Powertrain

Affects Chevrolet Volt · 2013 — about 265 vehicles.

The hazard

On certain vehicles, an error in a software update may prevent the batteries from properly balancing the voltage among individual cells. This may cause the vehicle to enter a reduced power mode. If a driver continues to operate a vehicle in reduced power mode, a loss of propulsion may occur, which could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will reprogram the Hybrid Powertrain Control Module 2.
