This has got me really freaked out. My scions only four months old and not to many miles on it yet. i took it out tonight and all of a sudden i can hear this sqeaking noise like two meatle things were coming into contact with eachother. The rate of the sound increased as I accelerated. After a little bit of driving the noise completely goes away and everything is fine. I asked my dad to take a look at it and suggested that something may have flew under my car and got stuck. I really think its something by my right front tire because i had a little accident and had a big dent in my bumper thats been pulled out. Is my dad right about something getting stuck under my car?? or is it a rotor problem??
