Is there a very known way to say that something asks for more problems? In other words, that a new solution, for example, is very likely to cause more problems than solve.
There is a colorful idiom for a solution that introduces problematic complexities: it "opens up a can of worms."
It could be said that "this solution is going to open a Pandora's box".
Money brings us happiness, but sometimes it just opens a Pandora's box.
