We test drove a 2017 Leaf today, done 21k miles. My wife and I both felt a dizzyness and nausousness in the short 20min journey. We couldn't figure it out. It was horrible and like nothing I've experienced in any car before. Took a good while to get over it. Really disappointed now cos we really wanted to buy a Leaf as our 2nd car. No way we can get one now!
There is no noise. Only vibration and resonance. At the time I blamed it on hard suspension, however, the suspension seems to get good reviews. I didn't see how it could be the motor because surely an electric motor should be infinitely smoother than say the rattling Land Rover diesel we are accostomed to.
Have you found anything more out about the problem? I shall contact a Nissan dealer in an attempt to find an explanation
