Just taken another look at your comments after posting my thoughts, and note your observations.

Some odd reactions and sequences it seems, but are they? Could be pointers at the problem. Are you 'driver only' most of the time? Better or worse, when you have a passenger(s)?

More I think on this, the more I'm minded it is in the 'sensing' of the car. Would be interesting if you have a passenger in the n/s rear and try roads you know well and how it clunks, see if the reactions are different.

I know you shouldn't have to bother and the garage should fix it, but always helps to have reasoned observations to add weight to your case. Could help others get a quicker fix, if it can be identified.
