Self Adhesive Wall Tile Backsplash

[CarWin]

Having an issue in our new 2018 1/2 3701LK. The tile backsplash is pretty to look at but horrendous to keep on the wall !! Its residential style tile,NOT designed for mobile units and or fluctuating temperatures. They keep coming loose and some even have fallen off and folded into half onto each other, thus making them impossible to separate to reuse. Now waiting on factory to send replacement tiles.

Do you think it wold serve me best to put small dabs of silicone on each corner and in the middle before reinstalling, it should give it some flexibility Im thinking, and help them stay attached to the wall.

Open to other suggestions and or possible solutions to this issue.
