My new GLC 220d sports premium started a rattle noise form the instrument panel few weeks ago and it went to the dealer gain yesterday (17/02/16) and was told today the rattle is due to a problem in the front suspension and need replacing. I suspected this before as the rattle became louder when braking.

Unfortunately I need to book in with the dealer again next week when the parts arrive at the dealership to replace this.

The car was less than 2 months old (1200 miles on the clock) when develop both these faults (initially a broken connecting shaft in the motorized steering column adjustment).

Hopefully it's nothing too big of an issue. Sometimes odd sounds can be something as simple as a rock stuck in somewhere, but you just never know with these new vehicles, at least it was figured out here.

If you can find exactly what the part was and share it here, that would help.

Have the same car. And the same noise. Please share your dealer solution...

This could possibly be a duff batch of parts if it's the same thing ? Back in 2008 the wife bought a new Kia Sportage, within weeks it had a 'knock' at the rear. We booked it in for an inspection and the dealer just said 'not another rear damper'. It turned out to be a very common problem, linked to a duff batch provided to Kia by the shock absorber manufacturer. They changed both shocks with a different type and we never had any issues with the car again (well, until the Mrs hit the gatepost but that's a whole different story...).

GLC 250d rattle noise from the instrument panel

My car has only 280 miles and 3 weeks old. Tommorow I will check at the dealer. I read on another forum that antoher guy was complaining about the same problem and the solution was to change the front suspention.

Is it confirmed to be the suspension?

I'm driving a c220d at the moment with this type of noise (GLC delivery on the way)

Cheers

Have resorted to shoving felt tape in the gaps to try and stop it. Have the same minor dash rattle / creak with mine, around the instrument cluster, center screen, centre console, doors etc. The demo GLC 250d was the same. It gets better after a short drive however the journey to work every morning is not what I was expecting from a £50+k Mercedes
Wife's 2017 17 Clubman S on 18" run flats and sports suspension is rattle free on the same roads.

Hi,
I have the same problem .... very annoying !

What could create such rattling noise is from the front drive train (unit). Since the vehicle is designed for torque distribution of 60 rear and 40 front. What is happing here is that the front drive train is loose (lazy or hanging you may say) because there is no load while driving so the gears inside the diff or the spirals from the driveshafts are loose and knocking that caused the rattling noise.

I don't know if anyone tried before to remove the rear prop shaft so that it will act as a front-drive car to see if the noise is still there or not. (to be honest, I don't know if the car will drive without a rear prop shaft as there is no center diff lock). Maybe putting much smaller wheels at the rear (with engaging the slip sensor switch) is a smarter way to test.

Perhaps putting a thicker diff oil will help as well.

Maybe someone here can help me with my thought. Thanks
