W205 C63S SEATBELT NOT RETRACTNG FULLY

Ive got a 2018 C63S Coupe and they driver seat seat belt isn't retracting the last 30% of the belt so it just hangs there.
I was told that the mechanism went bad so I bought a brand new mechanism and had installed last week only to find that it does the SAME DAMN THING!!!
It retracts all the way up until the last 30% just like the old previous mechanism.
Any thoughts here?
Thanks in advance

Appreciate the responses guys - However, I called and checked online with my VIN and was told there are no recalls for my vehicle... hmmm back to the drawing board.
