I just purchased a 2014 Cadenza with 26 miles on it. Got a great deal after trading in my 2013 Optima that had 72K miles on it. Had the Cadenza for 11 days and on Wednesday I went to a store, was in there for 5 minutes, and when I came out it wouldn't start. Dealership is now saying it's the BCM. I'm concerned I got a lemon. Service manager assures me he's never heard of this issue. I can't find anything anywhere online that points to any issues. Has anyone heard of anything??? I'm a little freaked out
