This has been an ongoing problem. Sometimes I hear a rattle, squeak underneath my dashboard. I thought it was something in my glove box making the sound, but I couldn't find the culprit. I'm also hearing a sound like water sloshing around somewhere underneath the hood on the right side of the car. The sloshing sound seems to happen when my car has gone through the car wash. Of course the dealership took the car out and didn't hear either sound. No, I'm not crazy!
