Probably bet to replace the igniters. I am sure you can get parts for that grill but they will cost you. Before I do that, I would call weber to see what the warranty is on those parts. Also, check the panel in the front of the cook box where the burners come through into the cook box. If that is starting to rust, it will only get worse and eventually become a safety issue. Again, make a list of all the problems the grill has and talk to Weber Customer support. On those Summit grills, they have fairly liberal warranties and if they have the parts, they many times will send them to you for free.
