Tile loosening up

[360true]

We have tile floors in our 2014 Georgetown XL. In the middle of the kitchen there appears to be one tile that is getting loose and is lifting up slightly and cracking the grout. We have not had any water leaks or driving in flooded areas. There is no discoloration or damage underneath to indicate external factors.

Any thoughts and how to fix? We have no spare pieces of tile.

I have fixed loose tiles by lifting them and cleaning the area very well including the underside of the tile and replacing using a commercial adhesive and then re-grout.

Thanks. Don't know if I can get them out without breaking, however. How to determine if it is just the adhesive letting go or if there is a bigger problem with the underlayment.

Watched an episode of "Home Town" on HG TV where Ben was restoring an old Airstream TT. He and his wife decided to install tile in the bathroom and shower. He said that you must use a silicone based thinset (adhesive) and a silicone based grout in order to let the tiles flex during the "mini earthquakes" associated with road vibrations and stresses.

Great idea. Makes perfect sense!
