    My partner picked up a 2 year old renault zoe yesterday from a renault dealer. Drove it home and as we pulled up to house i could hear a loud humming noise (like a loud electric shaver). Thought to myself, no way should it be that loud (i have a bmw i3 and never heard any noises), so parked it and left it. Went to charge later and the same when charging, the loud humming from front of car kicked in again. Reset home charger and tried again and it was quiet. Drove today and when she got home as she pulled up i could here it again. Tried charging again today, resetting home charger didnt work in removing hum. Tried my i3 charging cable, same thing, tried a “granny” cable with three pin plug, it tripped out home ring mains. Went back to type 2 cable, humming again. Tried moving car and putting back on drive, same thing, humming started when charging, tried 5 times removing cable, resetting home charger, same thing. Eventually tried pressing electric button on remote when charging and pressing again and finally it started charging quietly. Im no expert but that doesnt sound remotely normal for a car. Its louder than most bloody petrol cars!! I have a short video if you need to hear it. Can anyone help?

    Sounds like the aircon which can turn on to cool the battery pack, does it get a bit quieter after a few mins? was it very hot where you are?

    Suggest trying the aircon set at low temp to see if its cooling ok after a few mins, if not the system may be faulty/leaking gas.

    Thanks Mo, could you elaborate on what you said, im a noob to Renault so need to fully understand what you are saying…..

    OK, so discovered something further today….when I turn the fan completely down in the car the loud humming from front of car stops immediately (this is when driving, not charging by the way). As soon as I turn dial up humming comes back. So you are seriously telling me this noise is “normal”? people put up with the hideous sound?…I cant charge outside my home at night because:
    1) It is embarrassing.
    2) It will wake my neighbours up (i’ve heard mustangs that sound quieter than this lol)

    Will it go away once unusual hot weather goes away in UK? Does this mean people in southern France and Spain etc have to listen to this noise all year because climate is hotter? Surely that cant be right?

    Are you serious? that loud humming is seriously deemed acceptable for a Renault zoe? I need to know where I stand when going back to the dealership so if someone can confirm everyone’s does this when its hot weather?

    Im in UK, I know you wont believe me (lol) but it has been above 30C since Saturday.

    Also, Air con doesn’t seems to be working properly as car not really getting that cold even on coldest setting and when switching from eco to normal drive modes. IS this related to the humming?

    So what is exactly wrong? could you outline it for a lamen’s so I know what’s wrong, what’s acceptable and what I can do to remove the noise? I will also attach another video with bonnet up so you can properly hear it.

    Cheers,
    Peter

    Working aircon is very cold, if I press auto it blows very cold after a few seconds. if yours is not blowing cold I would suggest its noisey because the gas has leaked.

    Zoe’s aircon is not normally that loud lol.

    Hi. I charge outside on the drive (no garage) and have never, in three and a half years, ever had a noise that I would find objectionable. Even charging yesterday in around 29-30’C, there was no noise – not even a loud hum. A very subdued one, but nothing anyone could object to. So I feel enormous sympathy for you but don’t know how to help.
    I assume you’ve been to your local Renault dealer? Mine is fully authorised to work on electric Renault’s and has a charge point free for anyone to use on the forecourt. If your dealer has the same set up you could try putting your Zoe on charge at their place and asking for their opinion on the noise. (I suspect your dealers are not as well geared up for EVs?)
    Re noise when driving, the only loud noise was when (see my separate thread) my air con pipe fractured and the computer attempted to cool the car with non-existent coolant. Of course it shoved the fan speed up to max but with, inevitably, no result. And the fan on max is noisy, even on my Zoe.
    Good luck.

    Thanks for all your comments i knew it wasnt a normal noise. Taking back to the dealer I tomorrow. There service centre said bring it back straight away so they can look at it but i dont think they are EV specialists but we have to start somewhere right?

    What I am confused about is why does it hum when charging? It should have nothing to do with the aircon or are they linked somehow?
