Well, yeah, sort of. I dropped off a slow leak tire at a tire shop once and they could not find the leak. They dismounted the tire, cleaned the bead area of the tire and rim and remounted the tire. The leak was gone - but this was an old rim.
 
I've seen leaks go undetected because the focus was so on the tire that the valve stem got overlooked. A little spit on the valve stem shows that leak and a simple tightening of the valve core stops it.
 
A small nail or piece of steel wire into the face of a steel belted radial might not leak at all right away. The tire may have to be running or sitting in the right position for it to leak. Water may not show this type of leak. The only way to find that kind of puncture is a close visual inspection of every sq inch of the face of the tire. It can be embedded below the surface and very hard to find.
 
A tire can roll freely over nails (etc) laying horizontally on or in a surface of rock or dirt all day long without penetration. It's only when the tire is slipped by spinning, sliding or turning while sitting still that the offending objects are picked up. Do you drive in an area that is suspect. If you never slip a tire or turn the steering wheel while sitting still it is almost impossible to pick up a horizontal object.
 
The fact that you have three tires leaking makes me think in a different direction, maybe. All tires leak very very very slowly right through the rubber. Usually not a problem and usually only a few pounds over a long enough period that it's taken care of by normal checking of the tires. If your tires are leaking this way, this fast, then they are defective and should be replaced.
 
The last thing I can think of is tires that lose pressure with changes in temperature such as going from summer into fall or fall into winter. I have added a lot of air in my tires since the end of summer. But, you said only three tires were affected, so that's not it, right.
