Okay so in the database it said "Evolves at Lv45" But whoa!! My Vibrava evolved at Lv54! Is something ...Wrong?
Vibrava can evolve at Level 45 and higher. If you didn't have a chance to evolve it before, it can evolve at later Levels. I'm going to assume you caught Vibrava at LV 53 at the sandstorm area via Poke Radar. It hasn't had a chance to evolve. So it can evolve at the next Level, assuming it has passed 45.
