Water Ingestion issue

What is this water ingestion issue I see on some threads. Still nearing my first maserati purchase. I read one thread that seemed like if you went through a puddle at high speed there could be a problem. Also one thread said something about if you take a turn to fast something leaked. Obviously, I am not an automotive expert but if I could get some clarification on these issues so I make sure to avoid problems if I can, I would like to. Thanks in advance for your help.
