What is causing my 2013 Kia Forte sx to make a creaking noise while driving.

Hello, sounds like a possible steering or suspension noise - a thorough inspection of components is needed, physically -- and then even to pin point when the noise is heard where it is directly coming from. Also, body insulators and mounts can make noise - so this can be inspected at the same time. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
