Got mine replaced under the Voltec warranty. That covers anything related to the electric half of the car.Bumper to bumper. Even though it has "Voltec" on it, it is NOT covered under the Voltec drivetrain warranty.
You might be able to convince a franchised dealership to replace it, and you might be able to get a Volt Advisor to get it replaced. However, it isn't covered under the extended Voltec warranty.
Mine was replaced at 99k.
