Has anyone else noticed the motor noise at low speeds? Mine sounds like a sewing machine winding up/down (not a flat sound but almost like an electric whump-whump-whump sound) while accelerating/decelerating at speeds below 35 mph-ish. I didn't notice this noise in my test drives but then I wasn't exactly looking for it. I was expecting a whisper quiet ride based on all reviews specially at low speeds where there is no wind/tire noise. It's not terrible, just something I wasn't expecting. Is this just my car (so I should take it to the dealer for a diagnosis) or do all I-Paces have this noise?
