I use the Voltec portable charge cord at home to charge my 2013 Volt. Typically, at 8 amps, but sometimes at 12 amps if i need a faster charge.

Occasionally, over the last couple of months, the car will start honking while on the charger. On the Voltec, the top LED will be green, but the bottom LED will be flashing red. I unplug at the car and the car stops honking. On the Voltec, the red LED continues to flash. I unplug it from the wall outlet. The car appears to always be fully charged. The next evening, I can use it fine without this happening.

Today, for the first time, the car continued to honk after removing the charge cord. The honking stopped when I started the car.

Anyone know what is happening?
