When I first start my car, and I’m only going about 10-15mph, the lightest tap on the accelerator, I hear a strange noise that goes on for as long as the car is accelerating (let’s say, up to 18 mph). As soon as I lift my foot off, it stops. It doesn’t happen every time and it’s so quiet that I can only ever hear it if I’m in a parking lot going very slowly. After about 5 times, it stops doing it altogether and my car “adjusts.” Any idea what it could be? ---

Maybe the serpentine belt is squeaking. I’ve had older belts squeak when cold or when it’s damp, then be silent after the car had warmed up a bit. I guess the belt softens a little after it warms up and makes a few rotations on the pulleys.
