Mercedes GLC 200
Braking without reason

Going backwards, it suddenly braked hard without anything passing behind it and without any obstacles that it could hit, the sensors did not detect anything around because they did not sound. It has done this several times going backwards and once going forwards. I have had to deactivate the three maneuver assistance options so that it does not do it again.
I took it to the garage and they told me that it is normal, that sometimes it brakes suddenly and the reason is that it detects a curb on the side. The fact is that out of the 5 times I repeated the maneuver it only did it once. So I wonder, when does it fail, when it brakes or when it does not brake?
I think there is something wrong and they are not fixing it.
Does this happen to anyone else too?

Relatively common on the sedan but might apply to the GLC as well:https://mbworld.org/forums/c-class-w...acking-up.html
