Experienced this issue when driving an almost new Giulietta in very wet weather with "Allroads" selected on the DNA switch. On entering a multi-storey car park with steep ramps and tight right hand corners, there was a distinct "clunk" when applying full lock on a number of these turns.

I was quite concerned, but otherwise the car drives fine. Consulted the supplying Alfa dealer, where the service manager suggested that this could have been due to the ESP detecting loss of grip on one wheel and cutting power/applying brakes as appropriate. As the wet concrete surface was quite slippery, I suppose this makes sense. Do you agree?
