There is any + N

This maybe weird to ask but seldomly I hear people come up with these statement:

• There is any problem
• This additional wheel would cause any problem

Is this grammatically wrong?

In these situation I understand as "There is not any problem" and "This additional wheel would not cause any problem"

It might be that I misheard the n't but I am not sure the reason why I miss this particular sound.

• There is any problem wrong
• There isn't any problem correct
• Is there any problem? correct

So when you think you heard sentence #1, you are right that you probably missed the n't. When people speak fast, it is possible that they barely pronounce the n't, but you should hear a longer pause after is, or a soft 'uh' or 'n' sound: There 'isuh' any problem / There 'isn' any problem.
