I am having the oddest issue, where there is an i termittent sound. This sound sounds like the bathroom faucet is turned on and water is pouring out, then the faucet is turned off, just like a faucet. The engine sound does not change, and I'm unable to find any other effects. The sound often starts after I hit a bump. Sometimes, letting off the accelerator causes the sound to stop, or at least the sound stops at that time. Not always, though.
