So I started my car tonight and right when it started it started making this squeeling sound for the first 15-20 seconds then went away. Any idea why this happened or whats causing it? Thanks

 

Sounds like your belt is slipping. After the belt spins for a little while, it heats up and starts sticking to the pulleys better. It will happen more when there is high humidity and or heavy dew. Tighten your drive belt, or if it's pretty old, get a new one.
