Chevrolet Volt Battery Issue Addressed Without Recall

Chevrolet Volt Battery Issue Addressed Without Recall

If you own a 2012-2013 Chevrolet Volt, you may want to check in at your local dealership.

The American automaker has posted a service campaign meant to resolve a problem with bettery coolant in the car that is being conducted by VIN  affecting the 2012 and 2013 model years. According to GM, some Chevrolet Volts weren’t filled with the proper amount of coolant in the Rechargeable Energy Storage System (RESS) because of air in the cooling circuit when it was filled. As a result, the vehicle’s battery cooling system has been purging any remaining air over the first 12 months of the vehicle’s life and could leave it with coolant levels lower than those necessary.

If this does happen, owners will see a Diagnostic Trouble Code (DTC) light illuminate along with the message “Service High Voltage Charging System.” When this occurs, the  charging system for the Volt’s hybrid battery will shut down until service is performed.

In order to fix the issue, dealerships will check the coolant level for the battery and if it’s at proper level, no further service will be required. If the coolant level is low, a system pressure test will be conducted to ensure there aren’t any coolant leaks. If there are no leaks present, then the cooling system will be filled, all the air will be purged and it will be topped off to the proper level.
