Have experienced the same thing, but you are right in saying that it is hard to re-create.
I file this in my "the dealer would think I'm crazy" book. I have a list of about five of these items that are not an immediate danger but ones that I am going to get entered into my service record before my first year is up.
My view is that if I can at least make them notate my account with it, then a year from now when something catastrophic happens they can't say I didn't mention it in the first year.
I don't know what else to do considering you cannot re-create for someone riding in the car. At the same time who knows? They could be the tip of a much larger iceberg down the road.
