Vehicles Affected: Approximately 50,000 model-year 2011-13 Chevrolet Volt vehicles
The Problem: According to General Motors, if drivers of the affected vehicles inadvertently leave the car in the On position, the high-voltage battery will drain and the gas engine will begin to run. If it runs for a long period in an enclosed space, such as a garage, carbon monoxide could build up, creating a dangerous environment. GM said it is aware of two related injuries due to carbon monoxide build up.
The Fix: Dealers will implement a software update that will limit the amount of time a vehicle can be left idling in the On or Run position for free.
What Owners Should Do: GM had not yet announced an owner notification schedule. Owners can call Chevrolet at 800-222-1020 for more information.
