Is there a term for an issue or activity that occurs only until the moment that you ask someone else to watch? [duplicate]

Is there a term for the coincidence that occurs when an issue ONLY occurs until the moment that you ask someone else to watch or help you resolve it?

For example, having an issue with software until you try to show someone, then it stops being problematic. Or an issue with the computer/phone that resolves as soon as a help ticket is put in.

The final example is when you have a problem with your car (funny noise, etc) - you hesitate taking it in for weeks because you know it will disappear as soon as the mechanic drives it...then it does.

This is different than a Heisenbug, where the action of applying a debugger, for example, changes the behavior of the activity being watched. It's also different from a 'works on my machine' scenario, where only the original user has the problem.

What is it called when a problem resolves itself just by the mention of it? Jinxing the issue? :)

I see this every day supporting my software product -- the users are experienced and are not making mistakes at one time then doing something different when I watch. The problems also truly resolve (coincidentally) as soon as they ask for help - they do not reoccur. I guess it's a case of synchronicity?

The closest thing I can think of is Sod's law, that as soon as you have an issue and ask someone to take a look at it, it suddenly resolves itself.
