    Screeching noise from 2018 CLA45 engine bay.

    On my way home on a rainy night, my car started to emit a loud screeching noise when I was driving less than 20MPH. Before this, my car was sitting for several hours in the parking lot. I only have around 12k miles on the odometer. I have not been accelerating aggressively either. Would anyone have an idea where and why this sound is coming from my car? Video is below.

    Sounds like water on the belt to me. Was that the only time it made that noise?

    Yeah I am guessing you’re right. I now remember I drove through a big puddle right before this happened!
