Two problems related to wiring have been reported for the 2012 Chevrolet Volt. The most recently reported issues are listed below.
The charger over heats and melts wires coating shorting the wiring cause charger to blow fuse leaving a fire hazard in your garage.
I charge my 2012 chevy Volt with the 120v charging unit supplied by the manufacturer. I use the charger in a dedicated circuit of 20 amps. However I have noticed that there may be a deficiency in the gauge of the wire used. The wire from the charging unit to the car becomes quite warm. However, the short cord from the charging unit to the wall plug becomes dangerously hot. So hot that part of the plug has melted and left burn marks on the wall socket. Even the wall is very warm indicating that the wiring in the wall is hot as well. I am concerned about a possible fire hazard at this point. Would you please investigate? I have attached a photo of the charging unit plugged into the wall showing the scorch marks from overheating. During this time, the car is stationary in the garage.
