W212 Seatbelt Failure

[a4angus]

I had a recent failure of front seatbelt inertia release - requiring complete replacement (apparently). Naturally this happened just before MOT was due.

Has anyone else had a seatbelt failure on a 5 year old, low mileage car?

It seems to me to be unusual to happen so early in the life of a car.

The reels can jam or stick if this was the fault, most can be lubricated to bring back to life
