  1. Creaking noises for ~30 seconds after parking. (Metallic / proportioning valve)

    Generation 1 Volt (2011-2015)
    15 Volt with 40k Immediately after parking the car, there will be a metal on metal creaking sound that comes from under the hood. While unrelated to the wheels, it sounds like a wheel slipping on the hub. (It's that kind of noise.) It will creak .... creak ....... .. creak....... then...
