When I first start my car in the morning after a cold night ( -5 or lower ) the belt will make a squeaking noise ( at least I think it is the belt ) for about 30 seconds or so. I don't think anything major is wrong but it is worrisome and annoying. I took it in to have it checked out and Hyundai said there is nothing wrong and it's normal for that sound to be heard on a cold start. Somehow I don't think so. Anyone know what's going on?
