Yukon noise
I bought an 06 Yukon, seems every other complete stop then begin to accelerate there is a strange whirring buzzing sound that sounds like it's just on the other side of the firewall. Almost like an electric motor retracting or winding something. I can feel it in the pedal while the noise is present. The sound lasts 2-3 seconds. What in the world is it, it drives me crazy?
