I can't tell y'all what the fix will be, but I can confirm that Engineering is up to their ears with it. I did a quick search in the TechLine database and there were dozens of cases all marked "Engineering Review". Please understand that we can't fix what we don't have a fix for, so Engineering does need to identify the problem and specify a repair before your dealerships can do anything. Please also understand that gasoline needs a specific 13:1~14:1 mixture in air in order to ignite, and that doesn't happen in free air. So while it may smell foul, you can quit worrying about your car lighting up, that simply won't happen.
