First stop should be the dealer, they may cover this under the Voltec warranty as mine was. Looks like you are in California? I believe the Voltec warranty is a touch longer than anywhere else in the USA. How many miles on your 2011?
It's worth a shot
(Note: this charger is the new one I got from the dealer in 2012 after they recalled the original 110V chargers.)[/QUOTE]
