Hey everyone!

Recently purchased a new GLC200 in Aus and have noticed a loud fan/sucking noise under acceleration. Is very loud when crusing at 1500rpm and tap the accelerator. I have a video but I don't seem to be able to attach it

Is this normal for other glc200 owners?

HMMM. That's not something I hear on my GLC... I'd bring it to the dealership. Probably under warranty?

I have the same issue when summer heat start 33C and when I run in city with panoroof open an AC on, I hear the vent very loud.
I undersood and my car before had same issue, that is an electrical safty fault on the fan system.
Normaly this can be changed in service, worst case scenario to change the whole fan as I do to my car before GLC 300. Try under warranty otherwise expenciv part to changed on your cost . Thanks.
