I have a new 2001 Sentra SE auto w/PP, and yesterday pulling out of the parking lot, the car was making some scary screeching noises while in motion. Quiet as can be when stopped, but making a horrible racket while moving. I pulled over, shut the engine off and did a look around, kicked the tires a bit, but didn't see anything wrong.

When I started up again, the noise was gone. Any ideas? It was really hot yesterday - perhaps the brakes locked in place for a little bit?
