Strange noise

[Hawklord3]

Hi , Just picked up an Ultimate hybrid, very happy, but have picked up a noise coming from the infotainment system on turning off the car. This noise lasts for 20 seconds and is a loud hum and is only present on turning off the vehicle. Not had a hybrid before, so not sure if this has anything to do with it. Any ideas anyone?.

Hi I've had my hybrid for 2 weeks and mine makes the same noise no idea why it does it but must be the norm I hope anyway

How is your mpg working out?., having only had mine 2 days, not really showing a true reading.

Between 37 to 40 which not bad since the weather been cold which battery doesn't like hopefully improve with warmer weather.

OK thank's , will let you know how mine is going . Have you spoken to the dealer about your noise. It is so regular that I think there is a logical answer to it, but any noises get you worried.
Do you have the tech pack, I bought mine out of the showroom, which did not have it, still cannot decide if I should have waited for one with it on, but then it would have put it over the £40,000 limit and cost more in the end, would have loved the extra bits though.

I've the same noise and what I think it could be is the fan on the charging pad still spinning, it's a fan to keep the phone from over heating as it's creates heat during charging. Now I could be wrong but it's coming from the same area and can't quite get my head in there.

No I think its a fan noise like Berty says so don't think there a problem. No tech pack I have the n line which am more than happy with enjoy your car.

Thank's guys, still think I will follow up with dealer/Hyundai, just for peace of mind. I am still in that honeymoon period, keep going to the window and looking out at it on the drive.
Had a 2022 kuga 1.5 petrol manual before, that was doing 37/39 mpg during the winter, warming up in the morning and with everything on, so this Hyundai has a lot to keep up with.

Did you identify the noise? If not, I was gonna say, you can disable the wireless charging pad to see if that is the culprit.

Mine does the same, always has. Seems to be coming from the engine compartment on mine. It's louder outside the car at any rate
