Query: This George (GRP99) is defective and could be dangerous.

I have had this new George Foreman GRP99 Next Generation Grill with Removable Plates for 3 weeks and last night it shorted out and nearly started a fire. I noticed when I first used this grill it didn't heat evenly. I thought that I was putting the grilling plates on incorrectly. But after last night, I'm going back to my older grill.Please be very careful with the new George Foreman GRP99 Next Generation Grill with Removable Plates.
