Clunk/thud when slowing to final stop

[caerfryn]

Hi
Just picked up the GLC today and have noticed a thud /clunk when coming to a halt. Can't really say if from front or back. Is this a common occurence and what is it?
Thanks in advance for any info / help.

Take it back.

I will be taking it back but was wondering if this is a known problem with this model.
