Front bumper is falling off

Welcome to 2CarPros.

If you are referring to the bumper cover, it is held on with a few plastic retaining clips and a few screws. They are inexpensive and you can get them at most any parts store. I can't recommend tape. I have seen people use plastic zip ties which are strong if there is one area, but not the entire bumper cover.

Can you tell me exactly where it is loose?

Also, here are the directions for removal and replacement of the cover. I'm including these directions so you can see everywhere it is attached and what type of retainer is used. The attached pictures correlate with the directions.
