S430 2000 with ~57K miles.
While driving, I repositioned my body to get little more comfortable and guess what? The seatbelt buckle unlatchesdby itself!! Just the driver’s one.

Later at home, I tried it several times and yes it made the "clicK" sound at usual but when I pulled out the belt (WITHOUT pressing the release button), it unlatched by itself!

I just never have seen/heard this kind of problem in any car before. Called the dealer and his estimate is $300 (part + labor)

Anyway, Has anyone experienced similar issue? Or have any advice in resolving it? Thanks in advance.

 

Ended up bought a new buckle from Dealer ($68) an replaced the current one. Works well now.

 

That's actually a serious safety issue. Wonder if they might recall the cars?

 

Yeah I would think MB would want to take care of that one for free before there are some lawsuits.... I can't think of a more serious safety defect. I would call MBUSA and see if that can't be done for free.

 

Need to replace front passenger seat belt buckle on a s430 Mercedes

 

If your are in USA report it to nhtsa so they start a recall
