Another kudo for Broil King warranty. We use our gas grill A LOT. 2-3 times a week, year round. More in the summer. Purchased in 2014. I keep it covered when not in use and clean it regularly. Last year they replaced all 5 stainless burners (lifetime warranty), at 6 years old. Not bad for stainless burners that get lots of use. Swap was easy enough.
Last week, while cleaning, I caught some rust-through in the body of the grill. My only regret about this grill is that it doesn't have a cast-aluminum body.... It's stainless, but, it's got a lifetime warranty, as it turns out. A call to BK, sent them a few photos. Today got a note to call and pay them a $15 shipping fee for a replacement grill body, side shelves and brackets.
Of course it's all on back-order, but, my grill works fine in the mean time. With just some extra venting
