When I drive my car and accelerate it whistles? What is wrong with it. Also on my car when I'm going over slightest on bumps I hear a rattling on left side near wheel. What is wrong with both problems? Thanks

Can you please shoot a quick video with your phone so we can hear the noise? that would be great. You can upload it here with your response.
