Late to the party...
I would avoid the current generation Summits completely. I know, I have two rusty hulks I am trying to figure out what to do with. One cost only $100 but wasn't worth it. Here's the firebox inside that you don't see unless you do some disassembly:
Florida tin worms are the size of our imported Pythons:
Regarding your Genesis II, I agree with the recommendations to contact Weber. I know these may not be perfect grills, but they ARE capable of better performance than you are experiencing. If you get that fixed, an upgrade to Weber's stainless bar grates would address your other issue. I don't think RCPlanebuyer is ready to start making these yet, and Weber's newest stainless bar grates actually look pretty good to me. (Not to rc standards, but certainly very adequate.)
And, there are always GrillGrates (sorry, Larry) which ARE available for the Genesis II. They will give you a notably higher sear temperature than the other options.

Best wishes on getting your grill to do what it should!!!
