just wondering if this is normal. when i first start the car in the morning, or if it's been sitting for a long time and i take off slowly, shift into 2nd, then as i'm driving in 2nd slowly i hear a faint sound from under the car, sort as if someone in the distance ran over a manhole cover, or something similar. only happens once, and under those circumstances then i don't hear it again while driving. you would need to have the radio really low or off to hear it.

happen to everyone?

The ABS system does a self check at a certain MPH every time the car is turned on. The ABS pump turns on for about a 1/2 second and makes an audible noise which is louder in the morning when it's cold, I could see it fitting the description you wrote.
