Suspension noise from a brand new EQA250

Hi guys, happy to join the forum.

I'm the owner of an EQA250 for about two weeks now, so far I really loved the car, only thing I don't like is a weird noise I'm hearing which seems a bit odd for a brand new car.

When the car starts moving from a complete stop, there are some sounds that I can describe as if something is creaking or stretching, which makes me suspect the suspension.
It comes from the front wheels area, could be only from the left wheel actually. I also heard it when de accelerating in some cases.
It can be heard when it is quite silent in the car, meaning with no music or AC.

Here is recording I've made:

Did any of you encounter this? Is it something common to a new car? I have only a few hundreds of miles on it.

I'd appreciate any input on this 🙏

Thanks!

Best advice would be to get someone else to drive it slowly around in an empty car park with you standing close to each corner of the car. That way you can narrow it down to one area. My only thought was could it be the automatic (electronic) brake releasing? Some other EVs can make a 'graunching' noise when first setting off or 'creeping' along slowly and you only hear it because the car is so quiet otherwise? Just a thought.

What sort of speed were you doing in the audio clip? Admittedly doesn't sound like the brake, more like a suspension arm bush (or something like that, I'm no Mercedes technician!)

Thanks for commenting.
During the recording I was pressing and releasing the the gas pedal slowly a few times. The speed was around 10 to 20 km/h max.

Mine make a creaking noise, I think it is the hand break deactivating/releasing. I guess cos it’s a heavy car rather than the suspension? It’s the same when I stop and park up, particularly if on slight incline. But If you are worried, take it back.

Had the same problem. One of the engine mounts was brocken. It was the production fault. The rubber parts in the mount separate and the mount was quite loose. Also the problem is located in the front area, the noise came from the back.

Interesting, did you notice it right from the beginning when the car was new?

I recognize the hand break noise, it's also a bit disturbing but at least it happens only twice on each ride. I don't think it's that...

I notice, when I stop on an incline, if I don't press hard enough on the brake pedal, the car moves slightly and in doing so creates a graunching noise, which I presume is the brake discs moving slightly against the pads, causing the noise. I think it's especially evident because the car is otherwise so quiet and well insulated. Brake noises, however, do seem to penetrate the passenger space more than one might expect.

I think, it was not right from the start, as the engine mount seems to be OK. There are a lot of automotive parts, that could not be easily checked after production. So a certain amount of them will simply fail in an early stage of there lifetime.

I had a creak from my EQC which was loose bolts on the big alloy bracket at the front of the battery. Once torqued up it was fine. Also a common issue is micro creep of the bearings in the front hubs. The remove the drive axles and put a special grease on them and refit. The dealer should be able to help..

I had the same noise on my EQC. There were two things.. mainly the front bracket directly in front of the battery. Bolts were loose. Once torqued up the noise was gone. They also removed both front drive axles and re lubed the splines and re fitted as the bearings in the front hubs had ‘micro movement’. Your dealer should know about this common issue.
