You might want to check the size of your starter fuse, to avoid a sudden no start condition. Apparently, the 20 amp original fuse was inadequate and should be replaced with a 25 amp fuse. This is fuse #23 for 2010 through 2012, and fuse #28 for 2013. If your dealer is alert, they may have already replaced it due to a service bulletin. My dealer didn't ... I found out the hard way.
