AM Radio Noise on 2006 Suzuki Aerio

I get AM radio noise.I find it can be stopped by slightly pulling up on the parking brake which turns off the daytime running lights. Dealer has tried a couple times to repair, but it's still doing it. Anybody else have this problem and has anybody had it fixed by dealer?

Hi,
Did you find out what was causing this problem? Did the dealer check all the ground wires for the antenna and the radio? Maybe the ground for the daytime running lights?
Thanks for any response you can give!
