General Motors is offering to perform free battery-pack inspection and repairs for owners of its range-extended electric Chevrolet Volt, to correct a potential battery-coolant issue in certain 2012 and 2013 models.

Due to the presence of air in the cooling circuit, some 2012 and 2013 Volts were not filled with the proper amount of coolant for their battery packs.

Over their first year on the road, the cooling system will purge any air from the circuit, but the process will leaves coolant levels in those cars below what is required.

If the coolant falls to a particularly low level, it will trigger a Diagnostic Trouble Code (DTC), and show a "Service High-Voltage Charging System" warning on the dashboard display.

This will also disable the Volt's charging system until the required service is performed and the trouble code is purged.

While GM is not issuing a formal recall, it will ask customers to make appointments with their local Chevy dealers for the necessary fix.

Dealers will check the level of battery coolant and, if it is found to be too low, add coolant and pressure-test the system for leaks.

If no leaks are found, the system will be purged of air and the driver will be on his or her way. Dealers will repair any leaks found, but GM will only cover that cost if the car is still under warranty.

GM is managing this service campaign by Vehicle Identification Number (VIN). Volt owners can call their dealers with their car's VIN to see if it needs the fix.

Owners can also contact GM at 800-222-1020 and reference service campaign "14114, RESS Battery Coolant level low."
