I purchased a Hyundai Sonata 2005 about a month a 1/2 ago well after a month of driving the car I started having some problems with the car. One of the problems I started having was under the dashboard, it gets hot on my legs and the passenger side gets hot also it gets so hot that I have to turn on my air to cool it off. My radio started making noise it would sound like someone was blowing into the speakers. And from time to time my brakes will squeak. I took it to the dealer and just because these things didn't happen when they checked it out they told me nothing was wrong with the car. I was also told when the problems start again to bring it back to the dealer but what if the dealer is closed or once I get there the problems stop? I could be out of town when the problems start again. And they did start again Wednesday night when I picked my daughter up from work I had my windows down and had to turn the air on so it could cool of under the dashboard. The people at the dealership really made me mad.
