Today my car gave the first signs of sickness after more than 6 months since I bought it. The car was running fine. In the evening when I was coming back from work, I started the car , left it idle for a few minutes to warm up, then moved slowly in the parking garage. I heard a screeching sound , which I suspect came from wheels. When I stopped the car the sound stopped. When I accelerated further the sound went away. Is there anything wrong in my 6 month old car?

Thanks
Kevin
