I have the "Brake Energy Regeneration" feature and I'm getting a whine that seems to match engine RPM rather than vehicle speed.
I know there's some known differential whine, but this sounds more like a transmission whine. Anybody has the same issue? Is it a GM tranny issue? Or is it just some regenerative braking thing that's being activated.
My old E90 (ZF tranny) did not have any whine at all.
