My dealer claimed it as a warrantee issue... didn't cost him a penny, therefore the same would apply with your grill... shouldn't cost the dealer anything except his time... and how much time goes into a phone call... seems he's feeding you a load of crap, like waving your hand around to get rid of a mosquito... Just keep after him, and send an email off to gary at paradigm, as suggested... he might take a bit to get back to you... but he will...
Tell him (Gary) that the dealer said he would replace the grill, and now nothing is getting done about it...
