I have been using 87 for my 2011 since February of that year., never a problem.
Try filling up at a different gas station next time. If still happens, then go to a different service dealer. You could have shot plugs which very very rarely does happen.
And if you do not have a tuner running or a turbo kit or a supercharger, 87 is all you need. Just as the manual and other threads about the 3.6 gas has been discussed.
Best for now.
