Zooming/buzzing noise above 100km/h (megane e-tech)

[PimvD]

Hi Folks,

Since a few days now I have noticed that when I drive above 100 km/h there is a zooming/buzzing sound from the engine. In addition, a slight vibration that occurs at the same time as the sound on the acceleration pedal.
Everything below 100 km/h very smooth and quiet.
I was wondering if anyone has ever noticed this or can point me in the right direction?

I also experience the same issue. My odo is 4000km and i have that humming noise since the very first kilometers. No increase or decrease with the time passes. Sometimes no noise up to 130km/h and sometimes it starts from 95km/h. Also noticable vibrations near 140 km/h. Seems like a tire balance issue but i think i can live with that issue.

Good news (may be)
Today i intentionally made several hard brakings at high speeds. And the noises are all gone above 100kph or so. Seems like brake pads in tolerance with disc and some surface trimming on pads helped on this issue.

Hi guys, it’s been like 3 days since I got my car and I am having the same issue. I will be contacting with the service department tomorrow about it. If anyone solved this problem, please let me know

When noise begins try turning on A/C manually by clicking on it regardless of the season and tempereture. The noise will gone magically.

Hello,

I'm the new owner of a Megane E-tech EV60 220cv optimum charge.

I've noticed the car, which is very smooth below 90 km/h, starts vibrating at 110 km/h and up.
It does not look like a parallelism issue. The whole car vibrates, not just the driving wheel.

It sounds like an aerodynamic issue, like wind flapping violently at high frequency.

Can others confirm if they have the same issue ?
