On the 2011-2015 Chevrolet Volt, first-generation Volts (2011-2015) can experience battery coolant heater failure. The heating coil is located inside the battery pack and can develop isolation faults, causing the vehicle to run on gasoline only when the battery is below 50 degrees F. The poor design placement requires opening the battery pack to test and replace the heater coil. A failing heater coil measures below the required 80 ohms isolation resistance. This significantly reduces EV range in cold weather and can trigger fault codes.

This issue also affects: Chevrolet Bolt EV, Chevrolet Silverado EV, Ford Fusion

Common Symptoms

Vehicle runs on gasoline only in cold weather (below 50F)
Battery will not charge or hold charge in cold temperatures
Reduced EV range in winter months
Engine runs constantly even with full battery charge
Battery coolant temperature warning messages

How to Fix

Have the dealer measure the heater coil resistance (should be 80 ohms). Replacement requires removing and opening the battery pack, which is a major service operation ($1,500-$2,500). Under the Voltec warranty (8yr/100k mi), this is covered at no cost. For out-of-warranty vehicles, some EV specialty shops can perform the repair for less than dealer pricing.

Parts and tips from 180+ owners who fixed this issue

TipIf your Gen 1 Volt only runs on gas in cold weather but works fine in warm weather, the battery coolant heater is likely failing. Have the dealer measure isolation resistance - below 80 ohms confirms the failure. The repair requires battery removal and is covered under Voltec warranty
TipKeep the Volt plugged in during cold weather. The Level 1 or Level 2 charger will precondition the battery before departure, reducing stress on the battery heater. Parking in a garage above 50F eliminates the need for the battery heater entirely
